One giant try square
How many times have you worked on a large project and wished you had a try square as big as a carpenter's framing square?
By adding blocks of wood as shown above, you can convert a framing square into an oversized try square for those big jobs. First, cut the blocks to size from 1⁄4
" stock and clamp them in position on the square. Then, drill 1⁄8
" holes completely through the blocks and square blade. Remove the clamps and scuff the blade with 80-grit sandpaper. Then apply epoxy glue to the mating surfaces, and reassemble. Insert 1⁄8
" brass or steel pins of the appropriate length. Hold the assembly together with masking tape until the epoxy sets, then sand the pins flush with the surfaces of the blocks.
