Question: How does it mount to the work bench?  Do you need a wooden work bench because I have a metal ones.
Document: This is a now stand vice. As you know vises were used over a hundred years ago when the average height of men was under  5 ft tall and the bench height was 34&#34;. So this is non traditional for a wood working bench. I am over 6 feet tall and prefer a higher working surface. This clamp sets proud of the bench and lifts your work about 5 inches higher than the bench (bench is 35&#34; tall).
You may still need a bench vise to do some of the crazy things we all do (like bending things back into shape, etc.
Like all Rockwell tools I've used it's very nice . . . but this one has some limitations and it could be redesigned much better. It's OK for some things but doesn't replace a woodworking vise ... although with some changes it could.Mounted on a normal bench BenchJaw is way too high for comfortable use with say a piece of 8" stock clamped on edge (so you can work on or plane the upper edge), unless you want to stand on a stool.
Works well, easy to mount, durable, got it on special for under a 100 bucks, couldn't be happier. Soon as I see it on sale again I'll get another one.
Just like Rockwell's JawHorse, the jaw mechanism on the BenchJaw doesn't disappoint. It's the mounting system however, that could stand some improvement. Maybe it's just me, but I planned on only mounting this tool when I needed it, maybe using some sort of clamping system incorporated into the tool itself. But that's not how it works, and instead a metal corner angle needs to be permanently mounted somewhere and the tool mounts there only.
Works great and installation was quite simple and fast.I wasn't sure I'ed really like this at first but it's grown on me.I really like being able to hold the work piece with both hands while clamping using the pedal.I do wish the jaws were not so short / shallow.Overall this works great for me even though it's not perfect.
Just got it a couple of days ago so I didn't get a chance to use it a lot yet but oh my, it really seems sturdy and well made. I was in the market for a vise gripe however I really didn't want a cheapo one at HH. One day I was checking woot and saw this before going to work, interesting. I was about to order it in the evening and it was sold out.
Installed this on my 42&#34; high workbench. This is the perfect height. I have used this to cut conduit, 1/2 &#34; bolt and 2&#34; PVC pipe. Holds everything tight and won't scratch whatever it's holding. Used it to hold painted cast metal to retap a stripped hole and didn''t scratch the paint due to the rubber on the clamp. Nice feature is to hold your project with both hand and tighten it with your foot. Easy release.
I'm serious: two seconds. So you work safer and better, and you don't lose any time. This is my kind of tool.
When I ordered it I wasn't sure if it was going to be useful. Installed it and can't imagine my bench with out it. I also have the jaw horse and can't say enough good about either.
Answer: yes
