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.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.
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.
