Daruma++ bolts Version 2 (on South Bend 9A)

These custom fasteners will be used on Mark Vande Kamp's Goodrich. They secure a fender stay and allow a rack to be installed without disturbing the fender setup. The fender stay is secured by a tiny M5 set screw which is run down a hole through the center of the bolt. The rack attachs with a M5x10mm bolt which goes into the same hole.

This photo essay shows how I made one of these fasteners.

Taking off a tiny bit of the OD to clean up the area around the fender hole. Without it there is sharp flashing exposed from drilling the hole.
