Awesome working vise. I have several benches and can't figure out where the best place is to mount this, but I can leave it loose for a while - it's so heavy and stable that it doesn't move unless it's with very large items is used. My projects usually consist of correctly sized pieces, so I think this will work without attaching it to the bench. The first thing I did was clamp the base of the mower in a vise to drill out the broken bolt. I've been waiting for this for months, but I just couldn't resist. Worked fine, the trimmer didn't budge. I have an 8" - very useful for many things but very, very heavy. Definitely recommended.
