Today I picked up a spray can of metal etch primer at the body shop supply store. Yep, expensive at $25, but I've got canned spray paint from this suppler before and hardware store paint doesn't even compare. I was going to have my bike powder coated, but decided to paint it myself.
Then, I got a seat of metric taps and dies in order to lengthen the threads of the caliper halves screws, which I have extended and am using additionally as mounting screws. Oh my gosh, my poor little vise had a hard time with the twisting needed to cut the m8-1.25 threads. For that matter, so didI! 2 and 1/2 hours of fighting! I had to put an allen wrench into the screw and clamp the wrench to the vise to keep the screw from twisting. i used a heck of a lot of oil but it was still really slow going.
Ain't OND's bike beautiful? Oh, what a feeling!
