Just for the fun of it some of the scrap from making a rosewood handle for dovetail saw is in the process of being used to make a small square for checking pins and tails for square.
A small piece of scrap rosewood was cut and then squared all around.
The hard part was finding something to use to make the blade. My first thought was to use a 0.040" feeler gauge. Then I remembered a piece of a ruler that came with a group of rulers purchased on ebay a few years ago. It was easy to mark with one of my gauges and cut with a hacksaw. It is kind of different ripping 0.031" steel with a hacksaw than it is to rip a piece of wood with a D8.
To clean up the edge a very shallow rabbet was cut on a piece of wood:

Another piece of wood was placed on top of this and together it was all clamped up in a vise so it could be filed down smooth.
After fiddling with it to get it an even depth over its length a slot was cut, different saws were tried to find which one made the kerf to match the blade. Turns out it was the band saw.
After a bit of fiddling to get everything square it was glued with epoxy:

One side is barely 3/4" and the other is not quite 1-1/2". This will work well with my most common sizes of stock.
After the glue dries overnight there will be some brass pins installed through the wood and blade for some added strength. Ace Hardware had some 1/2" brass strips that will be used on the bearing faces of the square. It will likely be a few days before much more can be done on this will post the next steps as they happen.
