14 INCRA Woodworking Tools & Precision Rules
General Purpose Fence
The essence of your INCRA LS Positioner is its
ability to accurately position your board for a cutting
operation. In a nutshell, it is a precision fence system.
Even when used as a joint maker, you are simply
applying a method of work to a very accurate fence
system to produce the many possible joints. Above all
else, the LS Positioner gives you the ability to make a
cut exactly where you want it, Fig. 32.
Using your LS Positioner as a general-purpose fence
is just as easy as using any other fence in your shop.
In fact, it shares in common four things that all fences
have: the straight edge or fence that your board will
be pushed along as you make a cut, a scale, a hairline
cursor, and a clamp. You will use your LS Positioner
as you would any fence. That is, first you’ll unclamp
the carriage, then you’ll look through the hairline
cursor as you move the fence. When you see your
measurement come under the hairline, you’ll clamp the
fence in place.
Of course, this is where the comparison ends because
unlike other fences, when you clamp the LS Positioner
in place, it is exactly where you want it to be. Just get
the mark on the scale close to the hairline cursor and
the Automatic Positioning Control™ of the patented
Lead Screw mechanism moves the fence to the exact
location as you pull the carriage clamp up to lock the
fence in place. It really is that easy. You’re sure to
find many cutting situations in your shop where the
precision of the LS Positioner will benefit you and your
work.
Joint Making
Joint making represents one of the most exciting
applications for your INCRA LS Positioner. Just
by applying a little technique to the considerable
precision of the LS Positioner, you’ll be able to add
joinery for box and drawer making to your list of
shop skills. The INCRA Master Reference Guide &
Template Library
included with the
Standard and Super
System Packages is
a complete source
book for joinery,
including step-by-
step instructions for
box joints, half blind
dovetails, through
dovetails, the INCRA
double dovetail and
the double-double
box joint, Fig. 33.
