I don't go through all that nonsense, just use high speed steel, low speed and 'enough' pressure.
The center drills are Harbor Freight specials, the 1/4" is a Dewalt Ti coated
I think drill is set at around 250~300rpm (haven't looked at it for years)
Stainless work hardens really quick if you back off pressure or have drill bit spinning too fast
As for pressure, that's an experience/practice thing
The 'pattern' is a 'nul' pattern
If you imagine some swirly diagonal lines it may show up? ;D

Did some more pointless dumb stuff
I fitted a grease nipple to pivot as I know they seize up and I know this fixed the problem
Also decided I didn't like the steps between parts and seams so smoothed things off a bit





Going to finish cleaning and re-finish with caliper paint, maybe more red ;D
Probably going to modify fluid inlet for a banjo bolt and stainless line

October 2014
Finally found the time (and pictures ;D ) to replace the images Photobucket moved when they 'upgraded' and messed everything up

Good idea on that grease fitting. I might nick that one for all my Honda's !

Re: CB360's - Speak No Evil, See No Evil, Hear No Evil-from build to blog

Got something almost finished today.
Been a bit down with all the issues so wanted to do something I could start and finish
As you all know, I'm slowly working on 3 CB360's and a couple of XS650's.
Stripped a 360 front wheel this afternoon, machined the 'fins' off then shined it up a bit.
Took lot longer to polish the spokes but they is now 'Shiny' ;D
Built wheel with new alloy MX rim.
Machined hub looks different, I'm building a 'Street-tracker style' bike
Here's some pics.
Completely stock



Machined and shined



Hub in built wheel



Complete wheel.



I'm going to make an alloy bearing spacer, just because I can ;D
I just took some thinners to the 'Pro-Racing' screen print on edge of rim
It's gone 8)
Forgot to mention, the rims are WM3 instead of stock WM1 & WM2
Not something I usually do or recommend, but, I'm going to run oversize 'trail' style tyres, probably 3.50 front and a 4.00 rear (or maybe a 4.10? ;) )

Worked on frame and got it primered.
Didn't like various bits of weld spatter and some of the welds so ended up re-doing a lot of stuff.
All welds around side stand are now smoothed off and the lumps are now 'fillets', all the high spots got ground off and all the spatter is removed.
Sidestand mount got some re-profiling so edges are now slightly radiused and all the engine mounts got sharp cut edges de-burred
Then, I thought, what the heck and ran some body filler around some of the welds to smooth things out further.
Probably 95% will be sanded off, but, it does make a difference to finished 'product'
Good chance 99.9% of people who see it would never know or care, I know though ;D
Here's pics from 30 mins ago
sidestand, 'outside'

Sidestand 'inside (I know, no one will ever see it)

Filler around steering head

Filler around brake pedal mount, lower engine rear mount and swing arm mounting

I'm going to start sanding ::)

PJ that's awesome! Are the fins required or not? What's the process for machining them?

If you raise you spindle speed, lower your table feed and lubricated with wd40 you can get rid of those last visible grooves on the inner surface.

Neevo,
I had wheel bearing out and chucked it in lathe with a center
Some castings are better than others and finish nicer.
I don't have power feed so had to do it by hand feed.
Machine isn't particularly rigid, I need a bigger lathe ;D (and somewhere to put it ;) )

Well it looks fantastic PJ. Not particularly pleased you put this up as I am now going to have to find someone to machine mine here in Sydney ;)

Should be able to find someone to do it relatively cheap, it's a pretty simple job.
I removed the bearing opposite the retainer, removed grease seal and opened 3 jaw chuck into bearing housing.
Center on bearing still in hub and carve away.
Hardest part was getting even radius on a high speed steel tool bit.
I made a lever arm with a nylon wheel to mount onto dial test indicator (DTI)
I didn't want to put steel tip of DTI directly onto anodised rim in case it got scratched up.

I need to make a second lever arm, it's a PITA swapping from up/down to side/side.
Because of leverage ratio it measures about 0.00075" instead of 0.001" so it's really about 10 thousandths up/down and 10 thou side/side.
There are 'ripples' on rim plus a slight flat/bump where it's welded together
Got a rusty old swing arm clamped in vice with a piece of steel angle to mount magnetic base/DTI
Took a couple of vids (less than 20 sec)

Re: CB360's - Speak No Evil, See No Evil, Hear No Evil-from build to blog

That's a really good idea PJ. I would have been tempted to just put a long section of tape on the wheel to prevent scratches......
