funny thing is I went to give a kid $1,500 for his big 250 pound vise that a friend needed for his shop and when I got there it was welded maybe 4 times. he said it worked better than it did when he got it so welds shouldn't matter. he'd put tractor bumpers in that huge vise to straighten it out and the vise would break so he'd pull out his welder and fix the vise and do the same thing again. well needless to say I didn't pay him for the vise and he NEEDED the cash cause he had an operation to pay for, but he completely ruined the value of a $3000 vise.
so if you think your hollow jaw Wiltons will handle anything you are mistaken cause i've helped hundreds of guys try to find parts for theirs cause they couldn't find a cheap replacement and didn't have $400-1300 to buy a new Wilton made in USA vise. sure Wilton sells their Chinese vises for $100, but they are not worth that in my opinion. I do like Wiltons but they weren't meant to be used for tractor bumpers or blades.
Ruff: yep using yours to sharpen your chainsaw is the job it can surely handle. i've seen and heard of two many guys using those vises on their hitches to bend something they did to their 4x4 or helping a friend and i've got more than a few broken vises pics i've seen that the guy wanted help cause he had no idea how much a Wilton bullet or Wilton Tradesman is to replace.
my bench vise weighs 178 pounds which is overkill now for my little garage, but it works on small jobs too and my wife and grandkids don't play with it. If you google Wilton vise diagram you might see a cut out of them showing their jaw towers are hollow.
