I made a burnishing tool so time ago and while it worked for my own stuff itseemed janky, I would have to use a nice one to see what they were like.
I have the Fox and Ohlins bushing tools. You push them in and out. Probably the same as yours. I have multiple sizes for the Fox one. Normal and race.

How did you make yours? I bet a tool post grinder on a lathe would make a decent one pretty quick. I set up my lathe to try and make one for a 38. I need to get some bar stock today at lunch.

@MikeD which ones are you reffering to ? Rnoks' plastic clamps or the aluminium ones?

I haven't used my Rnok's yet but I thought that if I did, I'd sand the 3D printer lines into the cavities to get more grip. It looks so slippery and the lines are not perfeclty aligned so I can see the shaft slipping.

Attempted to 3-d print some shaft clamps to disassemble a Charger RC damper. I forgot how much fairly solid chunks of Polycarbonate warps and it started to pull up from the base about 30% into the print and had to abort early. Still worked. Slipped at first but applying a little paint buffing compound gave it enough friction and isn't abrasive enough to do any damage.



Surprised to see a lot of nicely machined parts in the Charger RC damper as the only noticeable compression damping is via backflow through the LSR port. A solid shaft with no piston surrounded by high viscosity grease would probably do a better job.

Just make your shaft clamps out of scraps of wood. I was going to 3d print some for myself before I remember that wood is even more non-marring than plastic.

Those plastic ones I have still fucking suck.
If they are slipping try the buffing compound trick. That made my half baked piece of shit go from not working, to working just fine. I am guessing fine clay would also work.

Something I have seen done when using vice grips to not damage a surface is to apply a thick layer of hot glue on vice grips, lightly clamp until it hardens, then tighten for grip. Same process could work with shaft clamps.

The old timey times
I had a block of 6061 leftover from a camera mount project I just drilled a hole in and ran a bandsaw down the middle of.

When I looked up the cost of real clamps from a moto shop I shot myself in the head for how stupid that was since they're so cheap.
