There is really not much to this step.



Remove felt - The chess pieces probably have a black felt circle on the bottom to prevent glass on glass action. Remove this piece of felt. Remove any remaining adhesive using some acetone.

Test depth - The chess pieces should have a small cavity underneath the felt. I am pretty sure this is an artifact from the molding process. None of the cavities are the same depth, so you should take an LED and test each piece to make sure the cavity is deep enough to completely hold it. If it is not, you have two options. You can either spend you time carefully drilling out the piece with a quarter inch carbide tipped drill bit, or you can buy another set. After drilling a few pieces, I figured it would just be easier to get another set since they are so cheap. Hell it was a two for $10 deal, so I bought a couple of extra sets.
