In order to mount the router, a kit from Rousseau can be purchased, but since I had a PC type guide bushing with a 1/4" hole, I chose to purchase the following items from McMaster Carr:
- 98380A556 Dowel pin 1/4"
- 91420A330 Screw flathead M5.8 25mm
- 91217A175 Cone point socket screw M5.8 12mm
- 2739A38 Anti vibration thru-hole countersink, 90 deg., 3/16" - 17/32"
- 2915A22 Drill point countersink 5/64" - 3/16"
A comment should be made before the step by step procedure. Phenolic plastic is very hard and not easy to scratch, so I tried two ways to get the set screws to mark the plate. First, I used a Bessey mini clamp, you can see them on the bench, to press the set screw into the plastic. I did this by placing the metal end of the clamp on the set screw and the handle end above the plate. Then I tightened the clamp. This worked for four of the set screws. Hitting the plate above the set screw transferred marks from the remaining two.
Step by Step
- Remove plastic plate from bottom of router.
- Change to 1/4" chuck and add 1/4" dowel pin.
- Screw cone set screws into base as shown in picture
- Place guide bushing with 1/4" hole in plate
- Position router on bench as shown, with lift lock to front
- Place plate on router face up using dowel pin to center.
- Use spring clamps to hold router base to plate
- Use one of the methods above to cause cone set screws to mark plate
- Remove plate, find marks and enhance with center punch
- Use a small drill or drill point countersink to start hole.
- Drill hole out to screw body drill size, in my case a M5.8, 13/64"
- Turn plate over and counter sink hole using a single flute or thru-hole counter sink to proper depth
- Mount plate to router with flat head screws
- Using a scribe, mark lift hole on phenolic plate
- Drill 1/4" hole in plate and slightly counter sink on top side.
