Making Clamps

F

OR MANY PEOPLE WHOaren’t professional cabinetmakers, wooden
clamps are in the luxury-tool class. Good commercially-made
handscrews cost at least $15 in the 8-in. size. Materials to make one
cost less than $5.
Make the jaws from maple or another dense hardwood. The^1 ⁄ 2 -in.
holes must be carefully drilled square to the jaw surface and the same
distance apart. The spindles are^5 ⁄ 16 -in. steel bar. All threads are^5 ⁄ 16 -18.
Thread 5-in. of one end of the spindles right handed and 3-in. of the
opposite ends left handed. Make the nuts from^1 ⁄ 2 -in. round bar. Be sure
the tapped holes are square to the axis of the bar. Small file handles
will work well if you don’t have a lathe. Drill through the ferrule and
spindle and insert a small pin after assembly.
