Title: Take 2: CB750K2 Steampunk(ish) Bobber Thing
Post by: Noddy78 on Apr 19, 2014, 05:31:16
Hi folks, I finally tracked down a new bike for the next project (see the first one here: http://www.dotheton.com/forum/index.php?topic=33668.0 (http://www.dotheton.com/forum/index.php?topic=33668.0)):

With a view to go a similar vibe as the 350, but a bit different:

(http://www.atomicblender.com.au/Douglas/CB750 Concept-16 rear.jpg)

The first one was an exercise in learning mechanics etc, this one is more geared towards fabrication, so I'm learning to weld and fabricate etc. Stuck in temporary accommodation at the moment while we try to find a house, so it'll be a slow start, but once I get up and running it should be a fun ride...

After posting on the 'Isabel' thread, I am relieved to see you're using a second donor!

I'll be following this thread with bated breath.

Let me guess...I'll bet it was advertised as a cafe racer right?

Seriously though, I just finished reading about isabel, and had to pop over here. What a fantastic build that is, and can't wait to see what you do with this one.

Ignore them Noddy. There is always a band of myopic hard-liners with a grudge against anything other than a full restoration. God, how many restored CB750s are out there already. It's not as if they're a rare thing. Go for it, not just to piss them off, but to build the bike YOU want.

Pretty amazing stuff eh? I believe they're actually humans behind the keyboards, but it's getting hard to tell... imagine if we actually acted like that in real life...

So, a very small update, got to start pulling a few bits apart to see what I've actually got:

(http://www.atomicblender.com.au/Douglas/IMG_2063_zpsdc57f40f.JPG)
Yep, that oil would be from the stripped oil drain bolt. Like just about every other bolt I've found so far...

Yeah, that frame seems legit.

So it turns out Honda actually do odd-looking 9s on their frames instead of upside down 6s! Good to know, looked like someone had 'repurposed' a "1". SOHC4 scores a win!
Title: Re: Take 2: CB750K2 Steampunk Bobber Thing
Post by: Noddy78 on Jun 02, 2014, 19:33:18
So not a whole bunch to report as yet (apart from being up to 21 pages of drivel on SOHC4.net!), just slowly whittling away at small things I can do without a proper workshop. Pulled the wheels apart on the weekend, I think my rims may be due for replacement:

(http://www.atomicblender.com.au/Douglas/_MG_0548.jpg)
(http://www.atomicblender.com.au/Douglas/_MG_0554.jpg)

Though the rusted out spokes gave me a cool idea. I was planning on powder-coating or painting the new spokes black, but now I'm thinking a light surface coating of rust, then hit it with some Penetrol, will look better and suit the "patina" theme of the bike.

(http://www.atomicblender.com.au/Douglas/_MG_0559.jpg)

I'm also trying to track down a suitable vintage style white wall, and it looks like Shinko make the e270 in 19", but only in 4.00 wide. Not entirely sure it'll fit on the CB750 front end, but I'm hopeful! Defintely getting a bit too wide for a 1.85 rim though. So I'm now looking to see if I can find a 19x2.15x40H rim. Not an easy task it seems! Have put some feelers out to see what I can come up with, failing that I'll probably end up going with the same tyres that are on Isabel which are actually much better tyres... but it's not like I'll be getting my knee down on this bike anytime soon!

a) Glad to hear it.
b) It'll have wheels and an engine, they'll be attached to one-another, it should get the job done.
c) Yes. What would be the point in doing the same thing all over again?

the average american motorcycle rider wouldn't know a good functioning motorcycle if you ran over them with it
i was more reffering to a total lack of suspension with a "slammed" look
it looks like something a gang bangin' crank smoker would build and is so overdone, because like i said, any idiot can build one
dont get me wrong i think the steampunk fashion cues are pretty cool but what he has envisioned is not very creative and would be a poorly functioning motorcycle
i could see doing a steampunk on a chassis designed around an earles type front and a plunger rear ,this would really open up the canvas  :) and with some creative engineering could also function quite well

Let's try not to let this thread descend into another SOHC4 arrangement shall we? That's cool, you don't like the style, I agree, it's not hugely 'functional', but that's not why I'm doing it. And I doubt any idiot can build what I'm planning, but maybe they can... and good luck to them too if they can! I'm learning how to weld, braze, form metal to build a tank (who knows if that will come off), veneer and various other skills that will help me build various different bikes (and various other objects) in the future. This is the one I've chosen to do this time. The next one might be different. Your objections are duly noted, but it's not going to change anything, so if it's not for you, move on. Easy.

Sweet mother of God, what is up with all of the "no, don't destroy that precious SOHC 750 angel/holy grail/gift from the heavens"? Those SOHC4 boys are a bit touched in the head...

As for the question of functionality, that's purely relative. A brand new Goldwing has awful functionality...as a race bike. Point being, if certain things are done to a bike that hurts it's functionality, that's not really a problem as long as it's not meant to do those things anyway. So Noddy, if you plan on cross country trips with this build, then the hardtail probably isn't the best idea  ;D.

Can't say that steampunk is my most favorite thing ever, but from your concept picture, and seeing the result of your first build, I think it'll look good when it's all said and done. Have a blast with it......

...and maybe post a video of all the unused stock stuff being burned and beaten over at SOHC...(not that I'm a vindictive type of person or anything)...

I especially liked the bit where Terry suggests I should do this to a much rarer, older British or American bike... geez, imagine the shit-storm if this is the response I get for doing it to a Honda!

So, if I can't do too much building, I CAN do shopping...

So, a nice vintage Italian Ducati 19x2.15 40H I picked up from a bloke in Melbourne for $30...

And get the lot ready to send out for powdercoating:
(http://www.atomicblender.com.au/Douglas/IMG_1306.jpg)

I've also got a spoke sitting in a bucket of vinegar out the back that's got the chrome flaking off already (gotta love cheap spokes) ready to try a rust-patina'ed effect. Will be interesting to see how that turns out.

your reply (paraphrase) "its not as if customizing motorbikes will ever catch on" ha ha ha... mind you i kinda see his point about using a cheaper older brit bike.. like a villiers excelsior maybe?! i dunno i love your vision what ever bike you use.. seems like terry may have read up on steampunk and decided that a jap bike didnt fit the mould.

Well, I did say it was going to take a while... but slow progress is still progress....

Rebuilt the carbs, painted, polished and velocity-stacked:

(http://www.atomicblender.com.au/Douglas/IMG_2891.jpg)

Un-fucked what will be the tail-light and found some replacement pieces to make it (mostly) whole again (just the beginning of finding plumbing bits to recycle... Terry will love it):

(http://www.atomicblender.com.au/Douglas/IMG_2914.jpg)

Rims and hubs back from the powder-coaters, done in "Sahara Black", looks like iron, I love it:

(http://www.atomicblender.com.au/Douglas/IMG_2918.jpg)
(http://www.atomicblender.com.au/Douglas/IMG_2922.jpg)

And messed around with the rusting spokes idea. Colour-wise worked really well, unfortunately the sealer just makes them too shiny and is not particularly hard-wearing, so with that and the fact that the Radaelli wheel requires shorter spokes than the original means the test-spokes are pretty-much useless. But, worth a try. So I've since got some SS custom spokes made up and just thinking of other options for dulling them off suitably. Someone suggested Copper-plating them, and I think that's probably the next path do investigate, but I can't imagine an electroplater being too chuffed about plating 80 spokes...

(http://www.atomicblender.com.au/Douglas/IMG_2933.jpg)

Aaanyway, still no garage, but plodding along with what I can...

A fair bit of badly pitted chrome in need of stripping:

And this is the "frame kit":

(http://www.atomicblender.com.au/Douglas/IMG_4301.jpg)

(http://www.atomicblender.com.au/Douglas/IMG_4356.jpg)

Yep, those are wooden dowels, and actually look like they might have once been a broom handle... because that's what you need inside the frame of a bike, a nice wooden sponge that'll soak up all the water and let it sit there and rust from the inside out...

(http://www.atomicblender.com.au/Douglas/IMG_4364.jpg)

(http://www.atomicblender.com.au/Douglas/IMG_4365.jpg)

And this is the sleeve that does the actual work, runs at 1.2mm wall thickness:

(http://www.atomicblender.com.au/Douglas/IMG_4363.jpg)

So the question is, do we think the sleeve is strong enough for the job, or do I need to look at fixing/replacing the frame kit in some way (which I'm tempted to do anyway as it looks really badly done)?

I'd say go with your gut and "fix" the frame kit.  Just like we all say to not muck about with the brakes, the frame is one of those things to muck with either.  Also, that tail light came out very nicely, glad you were able to clean up the other persons attempt at brazing.  Looks great so far!

Definitely don't skimp on fixing the frame. Remember, this is 35 year old technology, Hillsy's pic resembles something you should think about in order to fix it properly; other than having a professional weld up the frame correctly to make it strong and like new again.

That or just buy another frame, it's not like their rare or anything.

(http://www.atomicblender.com.au/Douglas/IMG_4559.jpg)

It was just all bogged up with filler, without all of the rust taken out first by the looks of the state it was in.

And I've also been playing with what I want to with the frame. I was intending to go raw steel, but after a bit of playing around, I'm now thinking gun-bluing the whole thing could be cool, then hit it with some Gibbs Brand penetrant, so darkening it up a bit, but keeping the raw steel feel. Did a bit of a test tonight:

Raw:

Blued:
(http://www.atomicblender.com.au/Douglas/IMG_4583.jpg)

Hard to get the effect across in pictures, but I think it looks great. Dead easy, and adds another layer of rust protection but keeps the raw metal vibe I want to go with.

Looks pretty rad. What process are you using to do the bluing?

I just got a little bottle of Birchwood-Casey Super Blue from my Father-in-law to have a play with. Looks pretty damn good. I don't think anyone would have a tank big enough to hot-blue the whole frame...

Yeah nice, interesting option for sure. So is it a purely cold bluing product? How do you think it'll turn out longevity and durability wise?

Post by: Noddy78 on Sep 21, 2014, 22:31:45
I'm hoping the Gibbs Penetrant stuff will take care of the real long-term protection, the bluing is mostly for the look, and a little extra help, but I'll have to do a few tests when I get a bottle of the stuff. Will be interesting to see how it holds up.

Maybe you could save your pennies and get someone to forge you a new damacus steel frame.  :D

Funny you should mention that, I did have the idea of actually hand painting some intricate design all over the frame... still might happen given these results after a day sitting in a bucket with a salt-water solution sprayed on it:

Raw:

Blued:

You also might want to look at Birchwwod-Casey's "Plum Brown" - I did some faux case-hardening using that and some Benzion tincture solution; used a map-gas/oxy micro torch to "cure and pattern" - makes some pretty cool "patina"

gives a finish very similar in appearance to this:

The bezels will be brass-plated and the wooden parts will be super-gloss coated (think classic wooden boat style). The wooden gauge backs were hand-turned by a wood-working friend of mine out of Tasmanian Blackwood laminated with Huon Pine, and I think they are just awesome, very beautifully made. I was super-stoked when he showed them to me.

I followed your other build and enjoyed it, I'm liking the direction this is headed as well. I've been around gun bluing most of my life and I would not advise it for a motorcycle frame. It looks nice but it takes a good bit of care and attention to avoid surface rust. Parkerizing or something of that nature, something you'd find on a military weapon might work better.

Love the wheels and gauges though, looks very cool.

So.. engine tear-down over the weekend. Found just a little bit of metal in the engine...

(http://www.atomicblender.com.au/Douglas/IMG_5594.jpg)
(http://www.atomicblender.com.au/Douglas/IMG_5610.jpg)
(http://www.atomicblender.com.au/Douglas/IMG_5598.jpg)

The culprit:
(http://www.atomicblender.com.au/Douglas/IMG_5599.jpg)
(http://www.atomicblender.com.au/Douglas/IMG_5602.jpg)

It looks like the cam shaft had a blow out at some stage and the timing chain chewed up the valve cover... I can only assume the PO welded up the cam shaft and put it all back together (cam shaft was attached to the cam sprocket by only one bolt), including the stuffed valve cover and left all the bits of metal in the engine! But bugger it, that's what the oil filter is for, right!? ...

(http://www.atomicblender.com.au/Douglas/IMG_5595.jpg)

Luckily it looks like that did limit the damage, everything else actually looks OK. The only other suspect looking thing were these scratches on the upper crank case:

(http://www.atomicblender.com.au/Douglas/IMG_5609.jpg)

Thoughts?

So, I'm going to need lots of new bits! I'm thinkng 836 kit from Cycle X? What do you reckon?

(http://www.cyclexchange.net/Git_Kit_3+.JPG)

I'm going to need about two thirds of all that anyway, might as well just go the whole hog...

Those scratches on the mating surface of the crankcase look like a PO's gorilla attempt at removing the old gasket. Are they very deep or are there ridges?
Title: Re: Take 2: CB750K2 Steampunk(ish) Bobber Thing
Post by: john83 on Dec 02, 2014, 11:06:21
I would just make sure to take a very good look at the crank, crank bearings, and the rest of the crank case. Basically anything that whirls around. With chunks of metal that size in there I wouldn't be surprised to find something else that got scratched up. Better to find it now than to have it fail after you've got the engine all buttoned up.

I reckon you're right there. No ridges, slight gouges, nothing too terrible though. I'll probably take it in to the machine shop when I get the rest of it done and let them decide.

Having a look over everything else though, it all seems to be in good order. I'm thinking perhaps he never actually got it running again. All the bearings/gears etc look good. I'll go over them with a fine tooth comb when I've got it all cleaned up and before I put it back together, but so far the damage actually looks pretty minimal.

Nope. Well, that's not entirely true, the wood started out as a blackwood tree and I imagine the Copper and Zinc started life in the ground... but I digress...no, it's made from scratch.

Sorry mate, I'm not entirely sure what you mean... but I'll give it a go. That light started life as a carbide lamp. I found it for $20 on eBay and it looked like this:

(http://www.atomicblender.com.au/Douglas/_MG_0587.jpg)

The previous owner had added an extra lens on the back and side and converted it to a incandescent light (all very poorly I might add). So I had to unsolder all the extra bits he put it on to get it back to somewhat original condition (then a good dose of Autosol to get it all shiny again). I found a copper plumbing end-cap to blank off the back of the light and secured it with brass slotted domed screws and self-clinching nuts (I'll be mounting the final brake light bulbs etc on the copper end cap so I want to be able to take it on and off). Just to add to the plumbing theme I used a bit of plumbers tap to make a decent seal (though given it isn't finished it's not fully sealed - and you can see a little bit of light leaking out from the edges in the earlier shot).

The lit-up logo is there to cover the hole where the previous owner soldered his own lens in. I cut the brass ring out of sheet brass with a jewellers coping saw and used some rubber stripping to make a seal (probably the ahrdest part of the whole thing and I'm still not happy with it - freakin' rubber is a PIA to cut/shape.. anyone got any clever tricks for doing this?). The logo is hand cut (scalpel) out of black signage vinyl and attached to a semi-opaque tracing-type paper with a sheet of clear acrylic over the top siliconed together and then siliconed to the inside. 6 x 2mm SS domed allen head screws and nuts to secure it all in place.

The lighting so far is 2 x 60mm LED rings, one attached to the copper end cap, and one against the front lens for 'running' lights. As mentioned before, I haven't sorted the actual brake light set up yet, but it'll be mounted on the copper end cap as well (inside the 60mm LED ring).

That's pretty much it. Is that what you meant?

Post by: Noddy78 on Jan 15, 2015, 00:14:52
And then I just re-read your question and now I'm actually assuming you meant how do I finish the brass itself? I just Autosol Metal polish. Then let it age and patina as it naturally does over time. That's what I like about brass and copper, it changes and ages and ends up getting really nice character to it. Sometimes if the piece is a little more banged up I'll use Wet and Dry sand paper reducing is grits until it's ready to be polished. But I generally like to leave some of the bangs and dings as that gives it some nice character too.

Well, I did say it was going to take a while... but slow progress is still progress....

Rebuilt the carbs, painted, polished and velocity-stacked:

(http://i1273.photobucket.com/albums/y408/Noddy78/IMG_2891_zps77e6d015.jpg)

Un-fucked what will be the tail-light and found some replacement pieces to make it (mostly) whole again (just the beginning of finding plumbing bits to recycle... Terry will love it):

(http://i1273.photobucket.com/albums/y408/Noddy78/IMG_2914_zps9c8b4cd0.jpg)

Rims and hubs back from the powder-coaters, done in "Sahara Black", looks like iron, I love it:

(http://i1273.photobucket.com/albums/y408/Noddy78/IMG_2922_zpsf3d9e54e.jpg)

And messed around with the rusting spokes idea. Colour-wise worked really well, unfortunately the sealer just makes them too shiny and is not particularly hard-wearing, so with that and the fact that the Radaelli wheel requires shorter spokes than the original means the test-spokes are pretty-much useless. But, worth a try. So I've since got some SS custom spokes made up and just thinking of other options for dulling them off suitably. Someone suggested Copper-plating them, and I think that's probably the next path do investigate, but I can't imagine an electroplater being too chuffed about plating 80 spokes...

(http://i1273.photobucket.com/albums/y408/Noddy78/IMG_2933_zpsda8a6f19.jpg)

All my goodies from Cycle X came through so the engine is off getting bored and honed etc, should get that back in the next few weeks and I can start reassembling the engine. Hopefully in the meantime I'll get the frame fully welded up and will have a rolling chassis together!

OK, so there has been much progress in the last few weeks, not least of which is getting all the documentation/forms etc filled in with the transport department to get approval to even begin this project.. long story, but they've recently changed the laws here and you now have to apply to do any mods before you actually do them. "Please sir, can I mod my bike?" Anyway, one 12 page submission (and 4 weeks of bureaucracy) later I've got the official go-ahead (dunno what I was going to do if I didn't!). In the meantime to engine has been with the engine guys getting it bored out, honed and the new valves guides installed etc... that's been gone for 5 weeks... hopefully getting it back this week...

So in the meantime, I've been welding!

I figured it best to repair the entire frame (no more Franks Frame Kit - got one spare if anyone needs one?) in case they engineers didn't like it. Give them as little to complain about as possible I think. Rebuilt forks, lowered with new seals etc, tapered steering stem bearings, new brake piston and seals, a bit of paint... viola! Almost looks like a motorcycle...

New HD Studs (and scracthed-up paint):

This project is great! The work on this (and what little I can see of Isobel) is phenomenal, you've got a real eye for detail. I have to break it to you though, but 90% of the pics on the Isobel don't work any more.

Well done learning to weld - it looks really neat too! Are you going to learn leading sometime too?

Well done learning to weld - it looks really neat too! Are you going to learn leading sometime too?

Yep, going to get into some brazing for the oil tank... read on...

So... plans have been approved for the extension, so bike will be slowing down even more, if that's possible. But did manage to get a few things done in the meantime:

But I think I'll have to put it all away now until the renos are done... vaguely attempting to get the oil tank done before then though, but I might be being a bit hopeful...

It's probably more a case of utilising the tools/advice I had to hand. I think the box joints suit the era/style anyway.

Post by: irk miller on Dec 07, 2016, 09:07:50
Looks awesome.  Make sure you keep that thing sealed up super well.  Running the grain perpendicular on the sides of the box is going to make them want to curl up on ya like a taco, especially when the glue crystallizes.   
Title: Re: Take 2: CB750K2 Steampunk(ish) Bobber Thing
Post by: Noddy78 on Dec 07, 2016, 20:34:47
Yeah, to get the stripes going the right way I obviously I had to run the grain on the front and back the wrong way around, and I wanted to limited the amount of fingers running across the grain to those panels, so the sides had to go the other way. I had a nice snug fit and I used Polyurethane glue which expands as it dries, so I'm hoping that'll make the joints strong enough. And it'll get the 14 coat Spar varnish treatment too, so hopefully that'll help in the elements too. Though, I'm no word-worker, so it's all a bit of guesswork!

Hidden hinges on the inside of the box?

Nah, haven't done those yet. It'll all be external brass hardware to fit the theme.

Okey Doke... House is built, garage is mostly put together and I can start fiddling with Douglas again (the actress said to the bishop). Just in time for Photobucket to go crazy on me.. so looks like I'll be spending some time rebuilding this thread too... in the meantime, finally got my welding trolley made and got to do some little touch-ups on the frame:

First I needed to make something to touch it up with...

Ok, so house is nearly complete, work is getting a bit slow... must be bike time! I've been busy ordering all sorts of bits and bobs to get a good go at this thing over the Xmas break. I've got some custom fender blanks coming from Western Australia, I've shortened those pesky exhaust headers (just waiting on some bling before I weld them back together), stripped the tank and split it in two because I thought it was full of rust (it wasn't, but still needed to split it for other things anyway), learnt to lift-start TIG (how nice is TIG welding!?), and made some handlebar switches.. twice. Well, 1 and half times anyway. I think that's the bulk of progress so far...

Rightyho, been busy over the holidays mostly with fabrication type stuff and haven't really taken many photos of the progress.. but, cut down the exhaust system and re-positioned and re-welded so it all fits nice and snug and hopefully leaves enough clearance for the front suspension travel (and added some extra bling). Finished off the switches and finally got the oil tank brazed together. Ended up getting me ol' dad to give me a hand on that one after a few botched attempts, but has come together beautifully (IMHO). Also been getting some more wooden bits together to start on the seat and for a few other detail pieces. Also been butchering the tank repair a few times, but I think I've got it sorted now, so that's the next thing to try and finish up. Hope is to have this thing on the road within 6 months... Aaannyyway, a few pics:

So I've been doing a few bits and bobs over the last few weeks. Finally got some guards back that fit nicely, lowered the gauges as they were sticking up way too far, installed the battery box and piped in the oil tank. Also made a buck for my first attempt at making a tank because trying to fix the old one was giving me the shits...

Guard mounting is next on the list. Then having a go at the tank. Then there's just front remote MC brake set up, rear brake set up, tail light/number plate bracket, indicator mounting, seat, cabling and wiring. Then powder-coating and electroplating and I'm almost somewhere near a functional motorcycle... I wonder if it will actually go...

Title: Re: Take 2: CB750K2 Steampunk(ish) Bobber Thing
Post by: Noddy78 on May 21, 2018, 19:06:29
No, it's not bent, it's cut out of blocks of timber. A bit of jigsaw, a bit of drop saw and a belt sander to get the curve radiussed within a bulls-roar on each piece, then once it's all glued together it'll just be lots of sanding to shape it. Ideally I wanted to laminate the whole block together and bandsaw the curve, but I don't have a bandsaw, so had to figure another way around it with what I have on hand. Hopefully it'll work out!

Yep, the plan is the underside will be able to be seen (with the mandatory thousand coats of spar varnish)... though only subtly really. This seat was actually where the whole of the idea for the bike began, I liked the idea of having some really nice pieces that are only visible if you look hard enough, dunno, something about that tickled my fancy... that said:

Just put some pad for each cheek and leave wood showing.

I do quite like this idea. Not sure how it'd work structurally though, as I was planning the have the steel seat pan taking most of the load and the timber being a cover piece on the underside to hide all the bits and pieces of the upholstering. I'll think about that though, I do quite like that idea...

don't you have some kind of heavy underwear that you could wear instead?

Heh, that was what my wife suggested...

That is what my wife definitely didn't suggest...

Seat's almost there, just needs some upholstering. Might sculpt some of the timber a bit more once I get the upholstery on there, but I'll wait and see how it looks. Oh, and I'll swap out the clear tail light for a red one I think, the clear looks a bit odd to me.

Maybe you could have pocketed the wood under the pan and welded the bolts under the pan, and 4 is excessive just to hold pad and leather to the wood. Looks awesome though, glad you left the wood grain to show on the sides.

Edit: just looked closer and the bolts hold seat to bike and springs, double as pan attachment.

Your craftsmanship is inspiring. Bravo. How does the seat rest on the springs? Just some washers? or is there some more surface area like a bar that spans the 2 springs? Are you worried the stress of the springs focusing on small pressure points might split the wood?

Yup, 2 bolts for the pivot bar and 2 for the springs. They'll also sandwich the edges of the leather between the steel and the timber.

Thanks mate! And good points there too. Currently the springs sit on thick rubber washers, which I assume will be sufficient, but I might have to double-check that...

So finally got the upholstery done, in a nice Kangaroo leather... Bloody nightmare it was though... The wife and I ended up spending a good 12 hours last weekend going hard at it, but it resulted in a happy ending... ;) We did it, and re did it, and re did it, about 5 times in the end I think, trying to get everything just right, trying get the right feel for how much foam, and what density, and getting the bastard leather to work the way I wanted, but we got there in the end. So now it's varnishing the timber time and hunting down some nice buttons to finish it off.

Thanks all, I really appreciate all the kind feedback. But this one especially got me a bit misty if I'm honest:

In terms of craftsmanship and attention to detail, this bike is Hazan territory.

Max Hazan is my all time inspiration, such stunningly beautiful bikes (and works of art.. good god those things make me go all weak at the knees). I'm certainly not even remotely in his league, but I must say I was pretty chuffed to even be mentioned in the same sentence. Thanks so much.

That seat looks so comfortable! My ass just got jealous.

Heh, I'm not exactly sure how comfortable it will be, part of the reason for so many attempts was because I really wanted that really solid feel that a lot of old Chesterfields have, almost punching-bag solid. It feels pretty comfy to sit on in the garage going "brooom, broom", but not sure how it'll hold up over a long ride.. hopefully find out soon enough! But if nothing else, it's freaking solid!

So I've been making slow progress for the last little while, just a few little bits here and there to get everything together. Getting all the control cables made up at the moment and getting Dad onto sorting out the electrics.

Also made a start on the fuel tank yesterday - a neighbour dropped off a few old tanks he'd butchered to use as battery covers for an electric bike he was making, and thought I could use them. Which threw a bit of a spanner in the works because I quite liked the shape of one of them. So I decided to try and re-butcher it into something I can use. The tank had the bottom cut out of it, and was too small anyway, so I've made a new base and am in the process of attempting to make it larger but keep the same general shape... we'll see how it goes!

Heh, it's not as bad as it looks. The pegs hit quite a bit before the muffler does, it's actually relatively tucked-under and pivots pretty well over the centre-line (not quite obviously, but enough... well, should be anyway)...

It's a hardtail anyway.  Not meant to be a carver.  You're better off than me, if you're making it to the pegs.  I'm at 4" on my hardtail, which is about the minimum to get halfway decent lean.  Though I have hit humps over sidewalks and such coming in and out of parking lots and gas stations.  Nothing major.

Nice work on the whole thing.  Love the hard line front brake.

(http://www.atomicblender.com.au/Douglas/_MG_2937.jpg)

Is something I considered for my own build, since the bike comes stock with a cable actuated front mc which is now located on the bridge of my Hossack fork.  In the end I decided I didn't want to blow money on the hardware (or really know what was needed, though another builder filled me in on that eventually - I think their solution matches what you did).  I also decided I liked the look of my 1980's era spring wrapped hoses. 

Do you have any easy way of dealing with pulling the brakes off when needed, or is it just gonna be a matter of careful handling?  That seemed another possible sticking point, and given I've done field repairs (read bodge) like pulling off a caliper and strapping it to the bridge of the fork with a wrench holding the pads apart (done because the caliper was locking up), I probably went the right way for my ratty / abusive tendencies, but it is still an intriguing idea, and now I need to fax that sticky caliper anyhow...

Hokey Doke. Been a long time between drinks, but I have actually been quite busy. All the control cables are made and actually work! And I'm on the home stretch on the wiring now (not that it looks like it):

But most of my time has been spent trying to make the f$#king petrol tank. Turns out my old MIG set up just wasn't up to the task (neither was I really) so I had to get myself a new TIG for Xmas. It's been a long process of trial and error but I'm slowly getting there (will post up the first attempt when I actually get the final one completed). Goddam sheet metal is a cantankerous beast though! But, think I'm making some headway:

The original idea was to copperplate the tins (and let them oxidise over time) and matt black texture powdercoat frame. But I think the copper is just a bit much:

(http://www.atomicblender.com.au/Douglas/Colour Options.jpg)

So the next thoughts are leave it bare steel:

(http://www.atomicblender.com.au/Douglas/Colour Options 2.jpg)

Do some kind of bluing process:

(http://www.atomicblender.com.au/Douglas/Colour Options 3.jpg)

Or a nice off-white pearl:

I'm currently tossing up between the bare metal and the white pearl. Leaning towards bare metal. But still not quite sure...

If you decide to do a nice off white, I have a couple cans of 2k custom mixed for a Porsche Ivory White that was only used one or two years on the 356.  I'll have to check the years and paint code if you want, but they're sitting in a box and will likely never get used, if you think you'd use it you're welcome to have it.

Yeah, I'm so torn about colour. I'm thinking I'll get all the powder-coating done, see how it looks bare metal at that point, and then potentially paint if I think that'll work better. The decision may also be made for me if I can't get a good enough finish on the tank to go bare metal...

If so, that could look pretty damn awesome, and probably better than the pearl I was thinking... more of a flat ivory white (?) which could be very awesome. Whereabouts are you based? Postage may be an issue for paint?

Absolutely. I'll start it out all nice and shiny but after a few years it'll get quite dull and muted, I quite enjoy the way it'll change. I'll leave the brass and copper to do that naturally so it's just a matter of how I treat the steel. I'll have a play with that while the frame is off being powdercoated. The headlight is about 100 years old, so it's got some really nice patina I'll try and match/take inspiration from.

That's my inspiration for the next one... but anyway, probably should get this one done first. Lots been happening that doesn't actually look like much... but all the fabrication is complete. All the timber is finished (and buffed and waxed to fucking SHINY!). And I've been playing with bluing and browning the frame, and I'm now on to painting everything. Hopefully this week will be finishing off all the painting and I'll be time to go back together!

Noddy, will you share your bluing, browning, and painting process?

Fer sure... It's actually pretty simple, just a bit time-consuming (on the frame especially because you've got to do it a section at a time):

1. Wire wheel all the steel to get a bit of a textured finish.
2. Acetone clean up.
3. Heat the steel with a MAPP torch, apply Mark Lees Express Brown #2 (https://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/blackening-browning/express-brown-2-prod41671.aspx (https://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/blackening-browning/express-brown-2-prod41671.aspx)) - it'll be a bit patchy but that's cool because it'll give the blue somewhere to go.
4. Wipe off with hot water after about 30 seconds.
5. Clean excess with steel wool.
6. Acetone clean up.
7. Apply Perma Blue (https://birchwoodcasey.com/content/perma-blueģ-liquid-gun-blueing-3-oz-32-oz (https://birchwoodcasey.com/content/perma-blueģ-liquid-gun-blueing-3-oz-32-oz)) - no heat needed.
8. Wipe off with hot water after about 30 seconds, steel wool, acetone and repeat steps 7 and 8 again if needed.
9. Several coats of Penetrol (http://www.floodaustralia.net/products/paint_additives/penetrol.php (http://www.floodaustralia.net/products/paint_additives/penetrol.php)) for sealing and rust protection.
10. Several coats of marine grade oil-based satin polyurethane top coat.
11. Cross your fingers and hope it all turns out well.
12. If you're like me, hate the final colour mix, strip it all off and do it all again... ;)

No guarantees about the longevity of the finish, it's a bit trial and error, but we'll see how it holds up!

Noddy, after all the work it might have been prudent to do a 2K satin over the top to make it really durable etc. But no matter what it looks great!
Title: Re: Take 2: CB750K2 Steampunk(ish) Bobber Thing
Post by: Noddy78 on Apr 02, 2019, 20:07:55
Yeah, unfortunately you can't 2K over Penetrol, so it's all a bit of a compromise. From what I've read Penetrol is about as good on bare metal as anything, so I'm hoping that'll do the heavy lifting, and the satin is for the finished effect and some protection. Given the timber and everything else on the bike, I think it's really only a fair-weather rider anyway, and it'll mostly be stored under cover. So the theory is marine varnish should hold up pretty well under those circumstances. Theory is all well and good though... we'll just have to see how it performs. If it's no good, I guess I'm pulling the bike apart again...

Thanks folks, awfully kind of you! Not sure it'll be to everyone's tastes though... I'm not entirely sure how I feel about it anymore...

But, final wiring is almost done... and we have lights (again)! Hopefully this week it's getting it all into the battery box and hooked up to the m-unit and we (should) be away! Also been playing with tarnishing all the brass and copper bits as it was kind of looking like a Christmas tree with them all shiny...

Ok. I have to ask, how the heck have you paid attention to so many details and missed rebuilding the carbs?

Or was this a accident as a result of your tarnishing things?

Haha! Nah, I rebuilt the carbs a while ago but obviously it was cracked and I missed it. Started to screw in a new main jet and it cracked right through.

Not a bad idea Justinlonghorn.  On the other hand, it can't be too hard to find a rack of those carbs or have they all vanished over the years?

I picked up a rack of K0 sandcast carbs a few years ago at Mid Ohio when the swap meet was at the fairgrounds or wherever it was.  I needed them for a CB77 race project that never was finished.  Time to shed more stuff I think.

Point being though that those carbs were not hard to find and I'm sure you can get a rack of spares somewhere.

I know a guy here in Montreal with a sh*tload of Japanese bike parts - I'd bet good money he has a rack of SOHC carbs.  Want me to ask him for you?

CB750 carbs are super easy to find, especially through K6.  K7 and K8 aren't hard either, but finding good sets can be more difficult.  The bores on them wear out beyond use.  The Pre-K7 are all over Ebay in $100 range and swaps have them for half that.  The hardest thing to find when it comes to SOHC CB750s is the K7/K8 insulators.  The aftermarket doesn't have good fitting sets, so they're prone to leaking, and the stock ones without cracks are rare.

There's a trick with the K7/K8 insulators, in that you can use 2x each of the two NOS parts that are available.  Whichever ones you can still buy, you mount in the correct position.  The other two can be rotated 180* over and function properly for the other two cylinders.  Apparently Honda figured this out a long time ago, and instead of continuing to produce spares for each of the four cylinders, they only produced the insulators for two, as they are nearly identical once flipped over.  Probably irrelevant to this thread but maybe useful to someone else.

Thanks folks. Yep, quite a few kicking around in the US, but not too many in Australia, let alone Tasmania (and postage from the US on them is a bit stupid)! But luckily I've found a set up in Queensland that look to have a good #1 body I can salvage and are winging their way to me as we type!
