CB360's-from build to blog - 2013, MDS (Mo Dumb Shit)

Re: 665----667---------Neighbour's of the Beast

fuck pj, stop screwing up. look at that... your timing is a whole .00005 degrees off!

haha, in all seriousness. AMAZING work PJ. cant wait to see whats up next! im learning, but slowly.
 
Re: 665----667---------Neighbour's of the Beast

i really hope when you are finished you will have a guide to all of these mods for us 360 owners. this is good stuff

impressive work! PJ, are you a machinist?

Trained as a machinist in the 70's, mainly so I could make bike parts (it was mostly BSA, Triumph and Royal Enfield's then, except for the odd 'old' Honda :D)
Specialised in turning, +/- 2 micron tolerance on most parts (except the time we had -0.000mm + 0,002mm)

Re: 665----667---------Neighbour's of the Beast

great werk man! i love that yer machining all yer own shiz! keep it up....
 
Re: 665----667---------Neighbour's of the Beast

damn! looks good...

if you want to machine me one for my 500t forks id pay ya!

these mount around the fork lower tops right?
 
Re: 665----667---------Neighbour's of the Beast

Gotta love a ball end and rotary table!
Looks like a nice start PJ, I've been thinking about a brace for the 500. My front end is a hodgepodge though so it'll have to be one-off as well.
 
Re: 665----667---------Neighbour's of the Beast

Got these today,
CB360newshocks.jpg

eBay ad says France but they come from China. :eek:
Stupid fast delivery, 2 days freight. 8)
Almost get sent back because post office couldn't deliver (road outside house still messed up)
I was here all day last Wednesday (physical therapy Tues, Fri, Docs Thursday) so I know no-one tried.
If I hadn't e-mailed seller asking for tracking number they would have ended up back in China as I was expecting 6~8 weeks.
USPS 'tried' to deliver last week, seller sent tracking number with USPS unable to deliver notice message, today is 5th day without pick up .(they didn't leave a card)
I may make a new spring seat and eye to use original springs, these have 9 working coils, original has 12 working coils so is softer.
I'll have to get bike finished and try them before I make a decision.
Feels like gas pressure may be different in each shock but I wasn't expecting them to be 'plug and play' so it's no big deal, I'll just check and re-set pressure if it needs it.
Anyway, price is right, good base even if they need rebuilding (and, I'm curious to see whats inside them :D)

Re: 665----667---------Neighbour's of the Beast

Well that just up'd the game a little bit, haha. Nice shocks dude.
 
Re: 665----667---------Neighbour's of the Beast

link to those shocks if they are any good! I want a good set of gas shocks, but it seems most of the ones off ebay just fail on people.
 
Re: 665----667---------Neighbour's of the Beast

They are ....decent....but as PJ notes, even if they need to be rebuild and/or tweaked the price is ok.
Beware the clevis if you get them for your Honda, notorious for breaking but it's a simple part and not too bad to have machined. They are a touch under damped and really firmly sprung so keep that in mind.
The materials seem to be pretty good and other than the aforementioned bum clevis the machining is pretty good for the price point.
 
Re: 665----667---------Neighbour's of the Beast

More bits turned up today, going to be a busy weekend

Re: 665----667---------Neighbour's of the Beast

Pretty damn annoying, the fork brace I spent 8hrs (+) on last week wont work and is scrap.
It worked OK on paper and I though maybe I could salvage it with 6mm instead of 8mm bolts, but, no go
Spent all day cutting and drilling 'new' design
MkIII is same as MkII except clamping bolts are about quarter of inch further apart.
Took way longer than expected but I spent a lot more time checking measurements, marking out, drilling, tapping.
As soon as I stamp 'A-A' and 'B-B' (so they don't get switched later) I can machine centers out. Have to be marked because they will be fitted as matched pair.
Here's pic of old and new, you can see amount of shift in bolts on right pair (new on top)

Re: 665----667---------Neighbour's of the Beast

Spent all day today making metal chips
this is what first one looks like.
Still not finished, more radius work needed on backing piece anfd the bolt holes still have to be counter-bored.
I must be crazy, this is about 4 days so far (30+hrs)

Re: 665----667---------Neighbour's of the Beast

Well, just think! You could make them and sell them for, oh, $1000 or so to recoup some of the cost ;)

Pretty awesome work regardless - would love to see a bit more on how you're actually making them. Clearly not a program-the-CNC-and-wait thing.

+1 on that.

Those look great so far. Would like to see a vid on how you are doing them as well. Between you and Swagger there is a school of knowledge and experience that many of us would love to know.
 
Re: 665----667---------Neighbour's of the Beast

+1 on all that! remember its a prototype they get quicker after you work it all out.
 
Re: 665----667---------Neighbour's of the Beast

Hi Guys,
this is second prototype, quicker than first one that didn't work. (I gave up on that one after about 8~12 hrs)
It's still going to take some time to make, they are labour intensive.
I have a small 'benchtop' mill (1hp), rotary table and a bunch of different cutters.
Probably about same amount tied up in machinery as some people have in a good home computer ($2,500~$3,000ish, probably not a good idea to total it up :D)
Cutting, drilling and set up is time consuming.
It does make it way more exclusive though.
If I ever made another one for sale I would need about $250.00 which is just too much for a CB360 exclusive part, particularly as I would still not be making a profit. (although I think it will also fit a CB400f?)
I see the 'Cafe Fabrications' CB750 CNC bottom yoke (lower triple tree) is $650 for a CNC part, that's just a slab of alloy (bottom of big arse projects header page)
I timed how long my clip-on's would take, about 12 hrs a pair for the clamps (the bars are just bars cut up, about $30~$70 extra)
I could make 'slabs' faster, I just dont like the way they look-unfinished.
I'm beginning to think I should make an exclusive thread for machining stuff, it's still big arse projects ;D?

Re: 665----667---------Neighbour's of the Beast

I hear ya PJ - and I don't even machine the same kind of parts as you. Cutting metal is easy...... it's the "not coming flying out at you" part that will get ya.

But I would like to see a thread on smaller machined parts ;)
