Positioning the Auto Centering
Scale (Imperial Model Only)
Install the router bit recommended for the
selected joint pattern and set the depth of cut
as described on pages 2-3 of the INCRA Master
Reference Guide & Template Library.
Zero the fence to your cutter with the router bit
behind the fence rather than in front. To do this,
slide your fence to cover the router bit (the bit should
be inside the notch just slightly behind the front face
of the fence) and place your jig in the micro adjust
mode. Place a straight board against the fence and
micro adjust the fence position until you see the
router bit just barely touching the board, Fig 37. Pull
the carriage clamp up to lock your jig.
Slide the INCRA Auto Centering Scale into one
of the scale slots. You’ll notice on the right end
of the scale the words “Router Bit Diameter” and an
arrow pointing to the following numbers:

1. Slide the scale to position the
number that matches your router bit diameter directly
under the hairline cursor. Fig. 38
using the Auto Centering Scale
Unlock and slide the fence until you see the
dimension on the scale that matches your selected
stock width directly under the hairline cursor. Lock
the fence in place. Example: If you are centering on
a 6” wide board, slide your fence until you see the 6”
mark on the Auto Centering Scale under the cursor
and lock the jig in place. Now slide your joinery
template into one of the scale slots, position the
suggested center cut mark directly under the hairline
cursor and you are ready to cut the joint.
