MATERIALS:
1 (A) disk, hardwood two and three quarters inches in diameter by one half inch long
2 (B) handles, wooden branches one half inch in diameters by two and one half inches long
1 (C) cord, #21 nylon, 185 lb. test, 40 inches long
(D) paint, colored enamel
The buzz saw can be made from nothing more than a large button and a piece of string. However, it is more fun to make a much larger one from a piece of wood. The disk may be sawed from a flat board, but a better balanced buzz saw can be made by turning it from a solid piece of wood in a lathe. Choose wood with uniform grain so that the buzz saw will not be out of balance. While the disk is still in the lathe, the lathe may be slowed down to its slowest speed to paint a colored stripe around the rim. When a small paint brush is applied to the rotating disk it instantly makes a small stripe around the rim. Holes are drilled uniformly through the rim to make the disk sing a little as it runs. The two center holes are for the string and must be carefully centered on the disk so that it will be balanced.
Handles are recommended for the larger buzz saw so that your fingers won't get pinched. The cord is threaded through the disk and through the two handles, then tied securely so that the knot will not become untied under high running stresses.
