Built this jig so I could quickly center a mark for a mortise. In the past I would measure the width of the board and then subtract width of mortise and then mark it out (usually with mistakes and many different measurements). Now I just select the size of mortise I want and put the jig on and mark away. No math to make mistakes.
I generally build with loose tenons but this will work with integral ones also.
I made the most common sizes for which I like to use. I made one aluminum one that is 3/4”. It was a prototype and now I plan to make the rest from aluminum.
