The original is Swanson Speed Square and were made of aluminum. Designed for doing roof trusses.

Overkill, but here is the Wikipedia link...

They are 7" and 12" versions. Careful with the plastic ones. Normally, using them as designed would be similar to a square to establish a line drawn on a piece of lumber to cut to, so they are not machined square (the plastic ones, aluminum ones are) on the bottom of the small flange. If you are going to use them in the manner above, you may have to do some sanding to the "slag" left over during the manufacturing process.
Harbor Freight also has them for really cheap.

Got the stab tube socket glued in. Made a couple of fixtures to ensure the stab and wing tubes are parallel to each other in the plan view. Used level blocks to ensure parallel in the rear view.
I was getting tired of trying to measure back and forth on each side so I used the wing tube and stab tube to punch a couple holes in some 3/32" balsa. Then glued the wing tube balsa to some spruce and cut the ends off each piece so they were equal. Then it was just a matter of measuring the short distance from the end of the spruce to the stab tube. Very simple....once I figured it out. Cool thing is that having the blocks and the other fixtures assured the stab tube socket remained rigid while I glued it in.
It wasn't off that much, but because it is such a short distance between the sides of the fuse, any small change during construction of the fuse can make a big impact to how well the socket lines up.
