Tools List for How to Use a Speed Square:
– Speed Square
– Miter saw, to cut PVC baluster
– Table saw or router, for slotting PVC baluster

Steps for How to Use a Speed Square:
1. A Speed Square, also called a rafter square or layout square, has a 90-degree marking edge and a 45-degree marking edge.[BR]
2. The square can be used as a straightedge guide when crosscutting with a circular saw.[BR]
3. A pivot point allows the square to be used as a protractor for marking angled lines.[BR]
4. The square is ideally suited for laying stud locations for walls.[BR]
5. Built into the square are several scribing notches, which provide a fast, easy way to mark layout lines or cutlines onto lumber.[BR]
6. The perfect 90-degree corner of the Speed Square can be used to determine whether two boards form a precise right angle.[BR]
7. To keep the square close at hand, hang it on your tool belt with a hook or get a specially designed Speed Square pouch.[BR]
8. You can also custom-make your own Speed Square holder from a PVC baluster.[BR]
9. Cut the baluster to length on a miter saw, then cut a stopped slot along one side with a table saw or router.[BR]
10. Cut a [FRACTION 34]-inch-thick plywood strip to fit inside the PVC holder, and secure it with short screws.[BR]
11. Attach a metal belt clip to the opposite side of the holder.[BR]
12. Clip the holder onto your tool belt, then slide the Speed Square into the slot.

great info on the rafter square – something you never mentioned – i love using mine for taking a 90 or 45 around a corner – ie side face to top face. you have to blag it with any other square. its a great precise piece of field equipment

Tom Silva is a fucking master! My grandpa was a cement mason primarily and general contractor. I wish i was older or my grandpa younger to learn some tricks. The days of “men” are dying out. We need more young people into the trade and off of their fucking phones.

Hey Tom. That’s not what the diamond cut out is for. It’s to mark seat cuts on common rafters. Only on Swanson. So original it’s Trade marked. You probably noticed how the speed square does not lay flat if you try to use it as a 90 degree square for the seat cut, hence the diamond.
