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,

.
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.
