<HTML>I have a very simple way to trim the wood off of the k= ey prior to installing plastic keytops.  My router is outfitted with a = set of blocks, which act as skis.  The tabletop is a very smooth and fl= at particle board type of material.   Clamp the key to the table u= sing a spring clamp, move the router back and forth over the top of the key = a couple of times, and you're done.   Maybe it's just me, but I ha= ve had trouble with any method that required moving the key.  I couldn'= t move the key smoothly enough to consistently get a level surface. This way= the key is held stationary, and the router skims over the top.   = I have only done one set this way to date, but it seemed to work well. Roy Peters</HTML>
