Hi,Richard! I usually saw off the old material: The new keytops (plastic) are in most cases thicker than the old ones, and some wood must be removed to get the same level (height over keybed) as before. If I just peel off the old keytops to glue on thicker plastic-tops, extra work must be done to level the black keys 12 mm higher than the white keys. A lot of additional paper under the black keys also gives a more unstable levelling of the keys. Because I always use new keytops with front (all-in-one), I prefer the sawing-technique to compensate for the (in most cases) increased thickness of the new fronts. If the old keytops can be removed very easily, I sometimes remove them before sawing...

I would like to hear a bit about why you all do this instead of using some form of heating up the the old keytops so as to "peel" off the old top / front material. thanks RicB Carl Meyer wrote: > This is what I use for cutting off the lip of the keytop front. > > Pass the key over the router bit very slowly. > -- Richard Brekne RPT, N.P.T.F.
