If not, it may walk or overheat, burning your paint.

Important - make sure bits are new and very sharp! This is critical. I've used 5/16ths and it works fine, which is also one of the sizes on my step bit. However, those exact sizes are hard to find. Tools to fabricate aluminum bar (one time thing): including vise, hammer, pliers, file/grinder (1' rotary drum sander in drill press is better), 1/8' drill bit.įinal hole size is 7.6 mm, or 19/64ths to be exact, for RivNut described above. Small electric or air drill, preferably right angleĭrill bit sized to RivNut, as well as smaller bit for pilot holeĮdit: Just found this 19/64ths step drill bit, which would be perfect for this, as it is its own pilot and perfect hole size: 'L' shaped hex/allen wrench to fit M5 bolt

One piece of 1/8' x 1' aluminum bar, about 6' long You'll probably use them in the future.Īt least one M5 x 0.80 bolt with hex socket head, about 2 cm long (get several though) When you order, since they are cheap get a bunch. I've tried stainless steel, too, but they are just too darn hard, and I've stripped bolts and nuts trying to install them. Ribbed 'L' Series Rivet Nuts - RN58033ALRĬan find them many places, but here's one (Google the part number) RivNuts - M5 x 0.80 threads (metric) splined aluminum I've done this on a bunch of bikes, now, and have for the most part perfected the technique. Since track bikes almost always do not include water bottle mounts, and since someone asked, here is a guide to installing them.
