Quick Tip: Two Easy Fixes for Your Woodworking Bench Vise
A good woodworking bench vise should hold a workpiece securely without requiring you to crank down excessively on the handle. If your vise slips or the jaws don't close evenly, a couple of simple shop fixes can make a big difference.
1. Improve Vise Grip with Leather Jaw Liners
One of the easiest ways to improve your vise's grip is to line the jaws with leather.
The leather provides a slightly cushioned surface that conforms to the workpiece, creating a secure hold with less clamping pressure. It also helps prevent the vise jaws from leaving marks on your projects.
Another useful accessory is a stepped spacer block. When clamping a workpiece near one end of the vise, place the spacer at the opposite end to balance the pressure across the jaws.
I cut several steps into my spacer block to accommodate common workpiece thicknesses. This helps prevent the jaws from twisting or distorting when clamping off-center.
2. Fix Vise Jaws That Don't Close Evenly
If your vise jaws no longer close parallel, the problem may be loose mounting hardware or repeated clamping on one side of the vise.
Start by checking the mounting screws. If they're loose, realign the vise and tighten them securely.
For a vise with a metal rear jaw, you may be able to add shims behind the jaw to correct its alignment. The goal is to restore even clamping pressure across the width of the vise.
Another option is to reshape the wooden front jaw.
Use a compass to scribe a reference line that shows how much material needs to be removed. Then carefully trim the jaw with a hand plane, planer, or belt sander until the clamping surfaces are parallel again.
A little maintenance and a few simple accessories can make an older bench vise grip better, protect your workpieces, and keep it working smoothly for years to come.
