Homemade Shop Vise Packs a Hydraulic Punch

It’s a sad day when one of the simplest and generally most reliable tools in the shop – the bench vise – gives up the ghost. With just a pair of beefy castings and a heavy Acme screw, there’s very little to go wrong with a vise, but when it happens, why not take it as an opportunity to make your own? And, why not eschew the screw and go hydraulic instead?

That’s the path [Darek] plotted when his somewhat abused vise reached end-of-life with an apparently catastrophic casting failure. His replacement is completely fabricated from steel bar and channel stock, much of it cut on his nifty plasma cutter track. The vice has a fixed base and rear jaw, with a moving front jaw. Hiding inside is a 5-ton single-acting hydraulic cylinder. A single acting cylinder won’t open the vise on its own, so [Darek] came up with a clever return mechanism: a pair of gas springs from a car trunk.

With a pair of hardened steel jaws, some modifications to the power cylinder to allow foot operation, and a spiffy paint job, the vise was ready for service. Check out the build in the video below; we’re impressed with the power the vise has, and hands-free operation is an unexpected bonus.

Yes, most people buy vises, but from the small to the large, it’s nice to see them built from scratch too.
