Rotor Winding Tooling

Excellent project, Jim.
A heads up. May want to check rotors before disassembly.
Here's a member UncleBuck's mis-aligned rotor.

Thanks Steve!
Yeah... that's the plan. First thing I'll do when I get one is check runout at the face and timing mark.

Oooh, runout. I guess you've already seen this.

Yeah... read that a while back.
First rotor done with the new tooling. It all worked just like I wanted it to.
Gonna let the epoxy cure before I solder the wires so's I don't make a friggin mess. Screws and washers are stainless and locktighted in, so I'm just gonna leave them exposed.... unless someone knows of a reason I should epoxy over 'em.

Great!
They grumbled a bit when I asked 'em, but no.... they don't whistle....

Lovely work there Jim.
Thanks Mick!
That's looking fantastic, Jim! I've been reading everything on this forum for years, and I've determined that member input has made such incremental improvements to every assembly on these motorcycles, they are better, without a doubt, by an order of magnitude, beyond how they left Japan, all those years ago... Performance, reliability, and ease of maintenance have gotten to "what 'MamaYama' should've done". You really have something remarkable going on! 
Fantastic Jim - this is going to be an excellent contribution to the XS650 community! These danged bikes will live forever!
Put me down for two please.

Awesome work Jim! Will you only be doing OEM cores? JC
Yeah, for now I'm just doing the OEM's
Speaking of pasting over the screws,
I think it'd be cool if you could put your rebuilders logo over them...

Now .....I’d buy a new rotor , just to have that logo on it! That’s awesome!
One step forward, two steps backwards.....
so.... The rotor above failed the runout test... to the tune of .015-.020" at the outer ring.
This was a rotor I'd taken apart last year before I decided to make all this tooling. Closer inspection revealed signs of previous abuse with a blunt object. Before you say it.... yeah, I'm gonna do a much better pre-inspection from here on out... hangs head in shame...
Anyway, moving on... had another rotor that I disassembled at the same time, so I pressed it back together to check face run out before I wasted another 20 bucks in wire and epoxy... not to mention the time. Ran true to about .001".
While checking it, I noticed a distinct wobble in the shaft the bolt goes through.... There's literally no way to bolt the shafts together straight with any kind of repeatability. That doesn't affect the runout check because runout is checked against the taper.... but it absolutely won't allow for a balance check on the knife edge. It wobbles up and down like an out of round tire.
Plan B... a single taper shaft....
Turns out this project has a steeper learning curve than I anticipated.... but I'm getting there.
