from The Century Dictionary and Cyclopedia
- n. A try-square the blade of which can be adjusted to any angle with the stock, and held at such an angle by a set-screw. It is an artisan's instrument for trying his work to see if it has been made with the proper angle. Also called angle-bevel.
Sorry, no etymologies found.
Set the bevel-square at the proper angle for a dovetail, Fig. 250.
Now with the bevel-square as already set, lay out the angle
Set the bevel-square so that it will fit the angle A B C, Fig. 250, p. 159, in a right angle triangle, the long side of which is 3 "and the short side 5/8".
It came to pass, therefore, that he was forced to make all the stones irregular in shape, preparing them with great labour by means of the pifferello, which is the instrument otherwise called the bevel-square; and this made the work so clumsy, that, as will be related in the Life of Bandinelli, it has been difficult to bring it to such a form as might be in harmony with the rest.
