Qwas Square - The Crosscut Fence for a Guide Rail
Square is for making cuts off of the MFT table. It is a precise 90
degree fence that slides onto the bottom of a Festool Guide Rail and
allows for accurate cuts while away from the MFT. It requires a
minimum of 8” of the rail which is about the same as the TS-55
The Qwas Square slides onto to the guide rail through the groove on the
bottom of the rail. It has 2 methods for accurate alignment with the
rail or you can use any square to align it. Two thumb screws lock the
Qwas Square in position. You can still install the hose guard /
deflector if desired.
You do need to remove 10-12 inches of foam rubber from the outer strip
on the guide rail. It is easily removed with a hair dryer and a scraper
or razor blade.
The Qwas Square is an aluminum plate about 17 inches long and 10 inches
wide. It is a precise 30/60 degree right triangle. It’s 3/16 inch
thickness provides for a rigid, sturdy fence while keeping it
Small screw holes have been added for adding an auxiliary fence. The
auxiliary fence can be wood or an aluminum extrusion. This fence could
have a scale and/or stops on it for cutting multiple pieces to the same
size. The aux fence could be used for any angle or weird shape cuts you
need to make.
How accurate is it? Good question and one that should be answered by
anyone making squares. We are keeping the error to .002 inch per foot.
This is close to the accuracy of a machinist square. However most
cutting errors will not be from the fence but rather from the reference
edge that the fence rides on. Any error on the reference edge is also
added to the total error. A thin 1/64 inch sliver on the reference edge
at the end of the fence can cause a 3/64 error over a 48 inch cut. It
is important to have a clean reference edge to get a good accurate cut.
That’s right, there’s more. The Qwas Square works with the MFT table.
With the use of our Qwas Dogs, the Qwas Square’s 90 degree corner can
be used to align the guide rail on the MFT. Also, the Qwas Square can
be used as a fence for cutting very accurate 30 or 60 degree angles
with the MFT.
