Jointing
Most woodworking projects require
that your boards begin with at least
one straight edge. This one edge
then becomes the reference surface
for subsequent perpendicular or
parallel cuts. By using your INCRA
TWIN and the setup described below,
youʼll be able to put a perfectly
straight edge on your board at the
router table, and because of the
higher RPM of the router, youʼll find
the freshly jointed edge far smoother
than any jointer machine can produce.
Install a straight bit
Install a
1
/
2
" diameter (or larger)
straight bit and set the depth of cut to
slightly greater than the thickness of
your stock.
Adjust fence gap as
necessary
See Gap Adjustment on page 12.
Set initial fence
position
Unlock the carriage clamp and slide
the fence up to the cutter. Adjust the
location of the fence to position the
outfeed fence in line with the
outermost cutting arc of the router bit.
A straightedge placed against the
outfeed fence can be used to help
align the fence with the cutter, see
Fig. 28.
Offset infeed fence
Set the desired infeed fence
offset by adjusting the infeed fence
backward. (See Infeed Fence
Adjustment on page 10.) Moving
the infeed fence back about .015"
(
1
/
2
turn clockwise with the black
micro adjust knob) should produce a
smooth cut.

Jointing
One of the most valuable features of
the INCRA TWIN LINEAR is the ability
to offset the infeed and outfeed
fences. The offset fence adds a whole
new dimension to the router table,
allowing it to perform two new
operations: jointing and shaping.
First:
Install

Second:
