Can I use any router table?







Yes.  An offset-style table is ideal, but conventional center-mount router table can have a
simple extension added to allow reasonable fence travel for the LS system.  Tips for adding
an extension are in the LS Positioner Owner’s Manual.

The quality of the router table will affect your results.  For an INCRA System to perform
properly, the router mounting plate must fit without play in the table opening, and the
reducing rings around the router bit must be very level with the surrounding plate.


I’m building an offset-style router table for an LS System.  What are the ideal
dimensions?








The outside dimensions aren't particularly important but the distances from the router's
center to the table's edges are worth considering. Parallel to the fence, the infeed edge of
the table should be between 12" and 16" (more than 16" can make the table uncomfortable
to use). Parallel to the positioner's carriage, the edge of the table should be 29" from the
router's center for LS17 Systems and 37" from the router's center for LS25 Systems.

There is quite a bit of latitude for shortening these ideal dimensions, and the LS positioner's
base housing also does not need to be mounted fully on the router table; it can be mounted
so that as much as 6" of the base housing's length projects off the edge of the router table.

What's the size of the INCRA Router Lifts and MagnaLOCK Router Plates?




They are 9-1/4" x 11-3/4" (9.250" x 11.750") in outside dimensions and 3/8" thick. The openings in Incra router tables are about 0.020" larger in each dimension. There is no industry standard opening, but this rough size is the most commonly used and Incra router tables and plates are designed to be compatible with Woodpeckers products.


I have a router table attached to my table saw.  How can I mount an LS Router
System so it can be easily removed?








The oval top section of the positioner’s base can be removed from the T-slotted sub base. 
This oval section can then be attached to a piece of good-quality 3/4” plywood and then
mounted in a variety of ways.

A wooden router table encourages using knobs through the plywood threaded into T-nuts
inserted into the underside of the router table.  For a cast iron table saw top, an INCRA
Miter Slider can be attached to the bottom of the plywood platform, and then the Miter Slider
can lock the plywood platform and LS Positioner into the saw’s miter slot where it can be
used with the router table.


Why choose the LS25 over the LS17?




The LS17 will likely cover every routing operation you’ll encounter, but the LS25 will rout to
the center of a larger panel.  The LS25 provides a 50% increase in capacity for only $30
more.  The LS25 could someday be set up as a replacement rip fence on the TS rail system,
while the LS17 doesn’t have the travel necessary for an everyday rip fence.


What’s the widest board I can dovetail?





The theoretical limit is the fence travel of the positioner, either 17” or 25”.  The realistic limit
is about 18”, though there are many cases where folks have gone well beyond that.  Bigger
material is a bigger challenge.  However, for the most common jobs like dovetailing drawers
and boxes, an INCRA System is far faster than any jig because it allows you to cut several
boards simultaneously.


How easy is the system to learn?





For the general routing you’ll be doing most, it takes maybe ten minutes to become familiar
with the system, and the accuracy and repeatability will spoil you on the very first day. 

For box joints and dovetails, give it an afternoon and practice with poplar before you get
into the middle of an important project.  The joinery instructions are clear, and the video is a
fantastic companion.   It’s not much different than learning to use a conventional dovetail jig.


How do the joinery templates work?









Each template has one series of lines for each portion of the joint.  On a half blind dovetail,
for example, there are two sets of lines on the template -- one for each board in the corner. 
For one board in the joint, you would lock the carriage make a cut as each line marked “A”
on the template is aligned under the cursor.

To make the mating cuts into the other board, you would stop at each line labeled “B” on
the template and make a cut.  The lines on the templates correspond to the mechanical
1/32” increments of the positioner, and those mechanics position the fence with an
accuracy 5 to 10 times better than your eyesight looking through the cursor onto the
template.


Can I add the Wonder Fence later?



Yes, the Wonder Fence works directly with the joinery fence on the LS Standard Systems,
and it will work with INCRA Ultra Systems that are equipped with the current Pro-II Joinery
Fence.


Do you use zero-clearance inserts?









The INCRA Router Systems achieve full zero-clearance with a very economical, convenient,
and complete solution.  Instead of using a plastic insert, the systems include hardware and
instructions for making zero-clearance sub-fences from scrap wood you already have. 
The subfence is cut with the fence fully locked, and automatically compensates for the pilot
bearings found on edge-forming router bits.

The sub fences can be used with the halves offset for edge jointing or moulding, allowing
zero clearance in a situation where an insert can’t be used.  It’s economical because
there’s no need to buy replacement inserts, and it’s fast because there is no second or
third cutting operation necessary to accommodate router bits with pilot bearings.
