Pretty excellent tips, dude! Thanks a bunch! 😃 Stay safe there with your family! 🖖😊

I love the knowledge of old tools from you guys but I can't agree with wood squares over metal 😅

Have you tried making a wooden T-square?

Wy have you not mentioned anything about grains in wood or species of stable woods and the differences. This is important information when making wooden tools! I have metal squares and I don't have any problems using them you just have to be more careful with them on soft woods. A combination square is a great tool. Allows you to gage the depth an height of things and make more accurate markings, cuts and check how even a rabbit or groove even ceek the corner's of your tenants for square. I use the combination square just as much as my large framing square also use a verity of machine squares for projects and tool maintenance. I find metal squares and straight edges more accurate but you can get by with wood for woodworking. You should still have a machine squares for tool maintenance.

Thank you Sir Joshua!

I didn't know they made torrefied oak. I tried torrefied ash for some stuff because it looked great, but it was not fun to work with. It was crumbly, brittle, and enjoyed splitting if joints were even just a little too tight.

I call my combo square a combo square it checks for 45 and 90 degrees in a mortice and the combo comes in as it acts as a shovel to dig out boring chips etc from the mortice without care. I notice your most used small square didn't have the ogee thing on the end of the tongue , I like that as it keeps the tongue full length on either side, is there a reason other than visual to have the ogee on the end?

"Wood by Wright" shows how to true a square (both edges) with a file. Haven't tried it yet myself.

Hm... this all sounds interesting, but you will need one first square as a reference. Or are you playing with the double error method?

I don't mean to undermine your knowledge. I have been working in this trade from a child and have much experience with the tools of the trade. Woodworkers and blacksmiths go back generations. A blacksmith or Machinist is not going to put a wood square up in comparison to a metal one! If you want a tool that will move far less and stay straight it's not made of wood. We all know as woodworkers that wood moves far more as it expands and contracts with changes in the environment. This is why we allow for movement as we build with wood more than metal!
