Allow a little space between them, as some cages fit differently, and others you might want to use in the future could be larger or sit lower. I try to mount mine as low as possible, but where they won't hit each other, and are close to symmetrical. Not essential but really helps.įigure out where your cages will go. Mount the frame in a stand, up high if you can. Then, wrap about 2 layers of electrical tape around the "legs" of the aluminum, so they won't damage your paint. When it's done, it should look like a "U" with square corners.Īfter it's bent, then drill a hole in the center of the center section just larger than your M5 bolt, I think about 1/8". ![]() Helps to use a vise, with some good pliers and hammer, if necessary. Don't worry about being too exact, because you can bend it again a small amount by hand to make it wider or narrower. Make 2 right angle bends in the bar, leaving a box U shape with the center section just wider than your frame tubes. Grind or file off all the edges and corners, making them rounded smooth. Take your 1/8" x 1" aluminum bar and cut a section about 6" long. The aluminum bar will be bent into a box "U" shape that straddles the frame tube, and both positions the RivNut screw and keeps the RivNut from turning inside the frame while you tighten the expander screw/nut. There is one tool you will need to fabricate first, and it is critical for a good installation, unless you want to buy a $100 or more tool, the aluminum bar. Tighten external nut, which compresses RivNut and locks it into place. Insert RivNuts with tools/hardware attached. Overview: Figure out where to drill the holes and mark. Stop and try as you go.ĭimensions: search for "M5" or " RN58033ALR" Mark the step where you want to stop ahead of time so you don't go too deep/big. If you use a step drill, get the shorter stubby ones, not the ones that are a couple of inches long. The step drill bit, I have found, works best, as it keeps the bit centered as it steps through the larger hole sizes. 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.
