I fit a jewel into a plate. It is a Seitz 30/200 (.3mm hole and 2mm diameter). The problem I have is that the jewel is too thick and I think touches the pinion on the third wheel where it’s installed. Is there a way of shaving material off a seitz jewel? Perhaps on a lathe with 2000 grit sandpaper or a burnishing file. Don’t know???? Help!

Turns out if you use a 2000 grit diamond plate, the one I use for sharpening gravers, and you hold the jewel with a short at toothpick that will not go through the hole, you can thin out the jewel.
