Many woodworking benches utilize a vise with a heavy steel screw. The problem is that grease or oil from the screw can stain your woodworking project. A vise with more traditional wooden parts is a better choice and can be just as functional. With the proper parts and tools, you can make a shoulder vise, tail vise or just about any type of vise you need.
Drill a hole slightly larger than your wood screw in the center of each of the two hardwood jaw blocks.
Insert the wood screw into the front block, and attach the screw's garter--the metal ring just in front of the hole for the handle--using a wood screw in each of the screw holes in the garter. Pre-drill a pilot hole for each screw in the hardwood before inserting the screw.
Affix the rear hardwood jaw to the edge of your workbench. Using the hole in the rear jaw as a guide, continue the hole all the way through the bench's end support.
Align the hole in the knuckle with the hole on the back side of the bench's end support. Pre-drill pilot holes, and attach the knuckle to the support with 3-inch wood screws spaced about 4 inches apart.
Insert the wood screw through the hole in the rear jaw and into the knuckle. Turn the screw to engage the threads in the knuckle.
Attach the wooden handle through the hole in the front of the wood screw.
Test the operation of your vise by closing the jaws and reopening them.
