I’ve got a case that I’d like to do some radial brushing on. A lapping machine is far out of my budget, so I tried to improvise this evening.

I secured the case between a nylon washer and one of my plastic crystal dies. I chucked it into a drill, and then used that to align it at the proper angle against a brushing wheel.

It’s clearly not perfect, but I think the concept is sound. I’ll probably need something different other than a thick brushing wheel to get the desired effect, so I’ll play around with it a bit more. I am encouraged that this may be a workaround to a very expensive tool.

Obviously a lapping machine can do many other things, but I’m just trying to accomplish this radial brushing for now.

About two weeks ago I came up with a very crude way of holding a case back centered and allowing it to spin so I can apply radial brushing to that part. It seemed to work pretty well.

The first two pictures are before my brushing attempt on the case.
