Make an insert for your sled.
You have made a sled, right? No? This a great time to make one! <G>
Using the sled, you'd cut a rectangle using the first two dimensions
of the triangle. Next, using two strips of scrap, screw a "V" inside
the sled, with the strips running all the way past the blade kerf.
Think sideways 90 degree miter sled. Here's an example I found in
google: <http://www.newwoodworker.com/mitrsldpln.html> See the 45
degree fences? Rotate them 90 degrees and use the INSIDE set to the
proper angles to make your triangle.
Set the angles properly using architect's triangles. A hold down
clamp would be optional. Now use the sled to cut the hypotenuse.
Removing the screws reverts the sled back to plain crosscutting.
Even if you need to build your first crosscut sled and buy the
triangle, you could do the whole deal for less than $25, and an hour's
work.
