A handsome, handy tool

By

A great little square with a million uses--squaring the sides of a banjo headstock or refining the tilt of a bandsaw table relative to the blade. Sturdy. Nicely calibrated. Easy to read. The body of the square (the head, I guess it's called) is actually 63/64 inches wide, not 1 inch as advertised. But that seems a wise and deliberate allowance for your pencil line. It's just something to keep an eye on in certain situations. The reason for four not five stars (I'd give it 4.5 if possible): The knurled knob you loosen to slide the head along the rule tends to bind and be quite hard to start to turn. My humble advice: Disassemble it, deburr the spring, add a small washer no wider than the knob, slather a bit of grease on the threads, and put it back together. It'll work nicely then.

Love it! Got the 6”. The ruler is thicker than their standard 6” rule (or a Starrett), and the adjustable beam is very well fit.

This precision double square came in handy when taking the center lines up and over tail block
and neck block when building stringed instruments. The precision double square also works perfectly when checking for vertical sides of stringed instruments if using simple homemade molds during fabrication. You don't have to be concerned with the question,"Is this thing square?" It definitely is
a precision instrument; thus a higher priced square. good for a lifetime of use and to be passed on to
a lucky recipient. Stewart McDonald did well on this one.
