square adaptor base plate.
12. Flip the square adaptor base plate
over. With the welded nuts now
facing downward, position the adaptor
plate on the router. (The welded nuts

holes and router holes aligned, insert
appropriate screws and tighten.

from your router base plate
are long enough to mount the square
adaptor base plate securely. If
necessary, replace with screws that are
1/8" to 1/4" longer.
