4.4 Pocket Depth Adjustment
The router bit for cutting the pocket is inserted into the router collet at the factory for a distance
of 1
1
/
8
” from the tip of the bit to the collet. This setting cuts at an optimal depth of approximately
3
/
8
” for material between
5
/
8
” and
7
/
8
” thickness.
To cut a shallower pocket (in ½” material for example):
• Place a shim with a known thickness on the work top and place your work piece over it.
To cut a shallower pocket:
• Remove the router motor as described in the section for “Tool Changes”.
• Loosen the motor collet and slide the bit to the desired exposure. (If the bit does not move
easily, try gently tapping on the bit near the collet with a wrench.)
• Secure the collet and reinstall the router motor.
For your convenience, a blank Bit Gauge (Fig 11) is included with your
machine so that you may scribe a mark to record the depth that is most
suitable for your purposes. Refer to the “Pilot Drill Depth Adjustment” for
this procedure.
