Jig Setup
1. With the bit you will use to cut the spline slots installed in a
table-mounted router, place the jig base on the router table
so that the bit extends through the center opening and the
expandable bars are in the miter track.
2. Adjust the base to roughly center the bit in relation to the
large opening and the black line on the face.
3. Place the centering gauge in the narrow slot and slide it up
against the shaft of the router bit. The "V" will center the base
with the bit. Fig. 1.
Tighten knobs fully to ensure sled is
securely mounted on the router table. Failure to tighten
knobs adequately could lead to serious injury.
4. Tighten the knobs to lock the base in the miter track. Back
the centering gauge away from the bit, lift it out and return it
to its storage area on the jig's sled. Fig. 1.
