I've looked at the Jawhorse and always thought it was a solution in search of a problem.
What do you use it for? Can you post any pics of it in action?
Thanks!
I can understand your skepticism, I was skeptical too before I used one - I didn't like anything that used an infomercial for advertising. Now it is one of the most used tools in my shop - seriously. I will never go without one.
The biggest difference between my expectation of a Jawhorse and the reality of it is the usefulness of the clamp. You can put massive amounts of clamping force on an item with a Jawhorse with your foot and the thick rubber jaws, and it locks and unlocks with a flip of a switch and a quick pump of your foot. It's an easy and natural motion to clamp something into it.
I'll see if I can get some pictures, but today I was using an angle grinder and a wire brush to clean rust off a snowplow mount for a Farmall Cub Tractor - the jawhorse held the heavy steel mount arms securely while I wire brushed them. They weigh about 30-40 lbs. The Jawhorse holds them plenty tight and makes it quick and easy to reposition them to get at all the surfaces. I have done the same thing when cleaning steel or aluminum wheels, or large bulky pieces that are hard to hold onto.
I recently cut an underbody toolbox in two to shorten it from 8 feet to 6 feet. I held the big bulky (and pretty heavy) box in the Jawhorse while I cut it and welded it back together. I often use the jawhorse to hold metal to cut with my plasma cutter.
I've used it to hold up pallet rack supports while I was installing the crossbeams. Just set the Jawhorse 90 degrees to the support and clamp it into the vise.
It works great to hold 2x or 4x lumber for cutoff with a circular saw - or really any piece of lumber that fits in the jaws - plywood, hardwood metal tubing.
I also have the optional welding kit for the Jawhorse, which includes an infinitely adjustable C-clamp that hovers over the jawhorse and allows you to hold parts to be welded together in almost any configuration. It works great.
Most of the time I use it as a portable workbench. I have a formica counter top section about 24 by 36 inches with a small chunk of 4x4 attached to the bottom - I just clamp the 4x4 into the Jawhorse and I have an instant workbench which has very large overhangs, so I can work all around it easily. I have another piece of steel that I can put in the jawhorse and use as a welding bench. I've even used it as a large layout table when I clamped a large piece of plywood into it. You can get a model that will clamp a full 48 inch wide, and it would have no trouble holding a 4x8 sheet of 3/4 plywood.
You might say " I think I can do all the stuff a Jawhorse can do in my bench vise" - well, I would say no. I have a Parker 5 1/2 inch vise and a Columbian 6 inch vise nearby - both very good vises - and the Jawhorse gets 10X the use of either of them.
First off, unless your bench vise is a huge one, it won't hold nearly as much as the Jawhorse - the Jaws only open a fraction as far on a bench vise, and it's not nearly as convenient to use. You can size and tighten a Jawhorse in a small portion of the time it takes to adjust a bench vise.
Most importantly, the Jawhorse is portable - I can take it where I want to work, rather than having to take the work to the vise. It's very sturdy, sitting on three legs, but it's not all that heavy or bulky to move around. Think of having a huge bench vise that you can put anywhere you want any time.
And finally the item clamped into the Jawhorse is much more accessible on all sides than when it is clamped in a bench vise.
I still choose a bench vise over the Jawhorse if I'm going to be hammering on something very hard, or I need to clamp something fairly small or need the metal jaws of the vise.
There are a couple of major differences from a Workmate - First off the workmate has a wimpy handscrew clamp, which is no comparison to the footpedal clamp on a JawHorse. Second, in order to be stable, the Workmate has a bulky base, which doesn't allow you full access around the item clamped in it. The Jawhorse has a simple, but very strong three legged frame which doesn't get in the way nearly as much. The only advantage the Workmate has is that it has a table top built in, but on the Jawhorse you can have any size table top you want by just clamping a piece of plywood into the jaws.
