keytop planer

[Rob Mitchell]

I'd have to agree with you Matthew, though actually, I have problems with
both designs.  The problem I had with the Genesis jig (aside from it being
somewhat expensive) is that I find I've got to go fairly slowly when loading
a key to make SURE the bottom of the key is flush against the tool base.
Seems like an easy enough thing, but the locking clamps tend to want to rock
the key up off the base if they are not precisely adjusted.  And if you
route without noticing this, it pretty much wrecks the key (ask me how I
know.)

 

I've started thinking about a variation on these designs with the router
fixed in place instead of moving around over a slot (Genesis) or back and
forth on rails (the Jim Bryant design in the Journal). I think I'd rather
hold the key flush against the base and move it in and out of the cutting
area.  It would seem that a jig with the router in a fixed position and with
an adjustable stop to limit how far up the key cutting is allowed would work
better and faster

 

Anyone tried this approach?

I wish I would of ran across those plans before I bought the Genesis Jig
from Randy Potter for $300.

Check out the Journal from November 2003. Page 10. You will see plans for
an easy to build jig to mill keytops using a router.
