AUXILIARY FENCES
Zero clearance
Adding a wooden auxiliary fence to the front face of your
INCRA Track offers several benefits. Often the most
important benefit is the ability to add zero clearance
backing for all of your crosscutting and mitering operations.
A zero clearance auxiliary fence for a miter gauge (Fig.9)
backs up your stock to provide tearout control during a cut
as well as carrying small cut off pieces safely past the
blade. In the expanded clamping mode, your INCRA Shop
Stop will still clamp to your INCRA Track with auxiliary
fences up to
3 ⁄ 4 " thick attached. Zero clearance auxiliary
fences are useful at any station where you want backing
support right up to the blade. Candidates for zero
clearance auxiliary fences include the miter gauge, miter
and compound miter saws and radial arm saws.
Extending stop range or fence height
Another reason to add an auxiliary fence to your INCRA
Track is to extend the stopping range or fence height when
used in conjunction with your INCRA Shop Stop. Say you
have an 18" INCRA Track mounted to your miter gauge and
you need to crosscut several boards to 30" lengths. By
adding a
3 ⁄ 4 " plywood or hardwood auxiliary fence that
extends the necessary distance from the saw blade and
then using your Shop Stop in the standard clamping mode
you can clamp the stop directly to the auxiliary fence.
Using the Shop Stop in this way allows use of taller
auxiliary fences as well.
Attaching an auxiliary fence
For auxiliary fence applications where incremental use of
the Shop Stop is required, the wooden auxiliary fence
should be flush with the top of the fence track. The
unmodified height of the INCRA Track is 1
9 ⁄ 16 " but if you've
raised the height for your application, adjust the height of
your auxiliary fence to match. (Fig. 10)
INCRA Track extension
INCRA Track sections are available in 18", 36", and 52"
lengths and should accommodate most of your jig and
fixture needs. For stopping range beyond the standard
lengths, sections of the INCRA Track can be attached to
your applications end to end. Just attach the track section
closest to the cutter first, then use a reliable straightedge to
align the second track before securing it to your application.
Attach the sawtoothed racks as though the joined tracks
were one continuous INCRA Track section, beginning at
one end and working your way to the other end.
