key trimming bit

[Farrell]

Dean, I don't know a darn thing about trimming keytops, but I have used spiral router bits a fair bit. If the router is above the keytop, shouldn't you be using a down-cutting spiral bit to minimize breakout? A downcutting bit should leave a smooth cut on the top (router side) surface at the potential sacrifice of the lower surface (although if there is wood bonded to the underside of the keytop, I should think that there will be no breakout on the underside of the keytop).

  I am using a Spurlock style set up to trim my keytops and am having trouble with the plastic chipping out on the notch cutting station. I am using a 1/2 inch spiral carbide up cut bit from McMaster Carr (27395A31). Is there a better router bit I can be using here?
