I got the Jesada Bits, and a new 3.5hp router (a craftsman, but I got
the $259 model for $125 in an open box). The problem now is that the
hole in the router table attachment on my table saw is smaller than
the raised panel bit.

My thought was to take a piece of luan superply, make a hole about
1/4" bigger than the bit, and permanently fasten a wooden fence to the
luan. This could be clamped/bolted/whatever to the metal fence.

The bit would be above the metal table and if if the router ever slips
down while running it will be interesting, but short of building or
buying a whole new router table I'm not sure what else to do.

Has anyone else ever succesfully negotiated this problem?
