AS-24 Adjustable Square

There is not on the market today a large square designed to meet
the needs of the woodworker. The options include a framing square
(awkward, designed for framing-not furniture making), and a large
metalworking square. There is nothing wrong with the large metalworking
squares available but they are expensive and to keep them nice you must
wipe them with oil before storage (oil is no problem in a metal shop).
Think of all the times you wished your squares were a little bit
longer... The AS-24 Adjustable Angle Square fits this need and more. It is the first large square available to woodworkers which is both accurate and adjustable!

The AS-24 Adjustable Angle Square consists of a blade,
handle and a solid brass turned knob. The blade is 24" long, satin
chrome plated, one and one-half inches wide by .080" thick. The handle
is solid rosewood, faced with brass wear plates which are secured with
an adhesive and flush set screws. The handle is fastened to the blade
in a "T" formation (similar to a draftsman's T-square). This allows you
to lay out lines from the extreme right of your stock to the extreme
left without flipping the square over-this eliminates the problem if
drawing converging lines which occurs from the error factor of all
squares. Now here is the neat part. Simply turn the square over so the
brass knob is up. At first glance the square appears exactly as it did
seconds ago. Now loosen the knurled knob (which has a perfectly
executed Brazilian kingwood inlay in the top), and you know have an
adjustable square with a full 180 degrees if infinite adjustment. The
fixed 90 degree handle is now on top. What this means is that if you
set the blade at 60 degrees, this square will automatically provide the
complementary angle of 30 degrees! You can adjust this square to any
angle you want (we recommend using a protractor head), tighten the knob
and the angle is firmly secured. Flip the tool over and you have the
accurate (plus or minus .006" over 24") fixed 90. Flip it back and your
previously set angle is raring to go. This is two squares
simultaneously!
