I've been debating purchasing a 12" Machinist's Square.

Problem is, can I justify $60-100 for a precision square.

For me that would be over kill when working with wood.

A couple of drafting triangles (8"-45 & 10"-30/60), along with a
couple of plywood factory corners can do wonders.

Don't forget the 3-4-5 triangle method of doing layouts requiring 90
degree right angles.

Before you spend any money, go to the library and get Fred Bingham's
book, "Practical Yacht Joinery" and read the section about measuring
tools.

Very enlightening.

Have fun.
