We did one on Frank B's 400. It will miss the mag.

Awesome, Thanks for chiming in. One less thing to worry about.

When you don't have a mill...  Not perfect, but not bad! Took me a while to make though. The caliper really takes up a lot of space between the forks. Looks like it will hit the wheel. Hopefully an optical illusion.

Quite impressive. That looks really nice.

Nice work on the caliper bracket,

Thanks everybody. I can't take full credit. This is Marks (m in sc) design.

More from the Neanderthal machine shop! Center of stock rotor to align new disk to caliper.
EDIT: Question for Mark - This is only about 10mm (or 0.4") thick. In your SPEED SHOP post, you say it should be 13mm (or 1/2"). Will this work, or can I space it out a bit more with washers? I guess I could mount it up and see for myself...

m in sc

agreed. if you cant shim the caliper in any further, and have it clear, you will need to make a 2-3mm shim behind the spacer, aluminum will be fine for this, ut im pretty sure you can space the caliper back and get it to work.


JBeasty

Got it. I'm guessing I shouldn't use washers to shim the caliper either?

m in sc

you can use washers or spacers to shim the caliper, thats fine. 3/8" id ones will work, you may want to get some thick washers or spacers for final use if that works.


JBeasty

Thanks Mark. Wheel is all apart to get powder coated, so I'll play with it when I get it back.
I got the top end installed, head came out OK - not perfect. But that's probably a good thing. Maybe It'll keep me from obsessing  and trying to get everything on this bike absolutely perfect.

I'm still here!! Putting my rear wheel back together and can't remember how the inner spacers go. Is it the first image or the 2nd?
