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.

Plug-in rack end : An experiment in making a plugin style rack eyelet or "dropout" for a rack. I started with 3/8" 1018 and turned it down to have a 5/16" OD and an ID to fit inside 5/16" x 0.035 tubing. The final result didn't have enough metal around the eyelet, so I brazed it and then cut it off to check my work. I'll try again keeping an OD of 3/8" at the eyelet portion. This will leave some more metal and make it stronger. The tricky part will be getting a smooth transition from 5/16" to 3/8". I think the final look is a lot cleaner than my tab style rack ends, so I'll continue to explore this approach. It is also easier to braze (but significantly more work to make).

Daruma++ bolts : DARUMA bolts are used with Honjo fenders to mount the fender to the bicycle frame. Mark Vande Kamp is building a rack for his bike and the rack needs to mount to the same point as the fenders. A goal is to make the rack remove with just a couple of bolts. I made these replacement Daruma bolts which have an extra threaded portion for holding the rack. There is a good photo of a normal Daruma bolt here (linked from Jitensha's page on Honjo fenders): http://www.jitensha.com/eng/images/lngshrtdrmascrws.jpg It is a pretty good simple lathe project, so I thought it would be a good thing to document. It has facing, turning and drilling and uses both the 3-jaw and 4-jaw chuck. The bolt is made of 303 (free machining) stainless steel. This was my first experience using it, it machines pretty nicely.
