keytop planer

[Farrell]

I thought the following quote from my previous post would have been enough 
of a clue:
"> Hi Fenton - I use a drum sander for many applications (not for keytops)."

 ;-)

I've never done a set of keytops in my life. Always have sent them out. If I 
were to do them, a small drum sander would likely work very well. I have a 
small rubber drum about 3 inches in diameter and maybe 4 inches long from 
Sears. I'd chuck that into my Shop Smith and grind away....
