    You do that with a knurling tool. They're pretty expensive, but they last a long time. I'm not sure of the method for doing a circular thing like a rim, but I use them for my homemade bashrings, and to make slightly small seatposts fit in frames with a better grip. There are a ton of uses for the tool. Very creative one on this post too. Let us know how it works out!

    It's not his rim by the way, the picture is an old one from vtcz. I have it on my otn album ;).

    It was done with a knurling tool, but wasn't recomended to others because the huge forces needed to knurl that pattern were enough to crush the rim, unless a crazy type of support was made. I guess also that knurling tools are pretty expensive, so grinding is still number 1. It was said to work very well in the wet, and of course lasts longer than a grind would.

    I made a jig to turn 20" wheels on a lathe. however, bolting it to the lathe faceplate and the cost for renting a 30x62" lathe was not worth it.

    i don't see how it's much different than the onza rims with the cnc'd brake surface to give it a very similar texture to knurling. apparently it wore down about as fast as a grind...

    I've had this suggested before, but speaking to a couple of machinists I know, supporting the rim on a lathe while you press a knurling tool against it would be difficult, as Roman said the forces would be likely to crush an alloy rim. Those implements of Trauma's look OK though.

    It might work on a Koxx rim since they are made out of cheese. :)

    but it wouldn't last on a koxx rim...because of the cheesiness...would also crush said cheese.

    Well someone needs to come up with a special rim knurling tool. Imagine the sales just on OTN :momaru:

    But wouldn't a texture completely perpendicular to the direction the rim is travelling stop better? Like say........I don't know........a regular grind? :rolleyes:

    I'm working a new top secret pneumatic design that actually works off the spokes. It kinda just shoves a stick in the spokes when you squeeze the lever. Zero modulation, but it locks up on command every time, no slippage whatsoever. Anyone wanna help me test it out?? I'll post pics as soon as the prototype is finished
