Hi

I am casting a custom-made dice in polyurethane.  The pieces have numbers engraved and these have to be in a different colour for high visibility.  I can achieve that stage quite easily but afterwards I need a quick and easy method of removing surplus acrylic paint from the facets of the dice and also to give them a nice smooth polished surface.  My options seem to be a polisher wheel with various grades of grit which would be too time consuming, hopefully I will get into serious quantities of this product.  My alternative method would be to use a tumbler of the sort used by lapidarists (gems and pebbles).  Can anybody advise me on success or failure in a tumbler?  Would it be a good idea to use something  other than polyurethane?

casting epoxy would be a good alternative to polyurethane. it is stable and will remain clear or whatever color you have made it.
can be drilled,machined as needed. can also be polished or painted.

Using a tumbler would likely round the dice. Also the grits would likely damage the paint finish.  If you've got easy access to one, then maybe try with a fine grit for a very short time.
