Hey folks! I should have posted this a couple weeks ago but forgot. I recently made my own try square. The blade is black walnut and the stock is cherry.
I sawed both pieces out by hand (if you look you can see that I could have done better; more to learn!) I shaved the dowel myself with just a chisel. My trick here was to pre-bore a hole into some hardwood so I could test the dowel in progress.
I decorated the edges with a coping saw and then cleaned that up a bit with a rasp and file. When I glued it up I used old brown glue, as recommended in The Anarchist's Toolchest, due to it's slow drying time. I really enjoyed working with hide glue! It cleans up much better than yellow glue. Will use more going forward.
I finished it with BLO and then soft paste wax (which I made as part of this project.)
If I had it all to do again I would have been more careful with my sawing, but the marks left aren't too bad.
