re: Height adjusts, but barely passes as a woodworking project.

Looking at those pics showing the roller stands clearly they look brand new. I believe when that was built they were at least 10 years old, and had been in the bed of my truck most of the time. They still look like that. Wear proof? Anyhow they still work as advertised, and the cheesy clamps have supported weight nearing 500 pounds. 2 times they had a car or truck motor on top of them, while a buddy rebuilt it. All I know is lifting them on wasn't an option, and we were beefy lads back then.. Used a chain hoist to lift em up. So this thing is stout when needed to be. They were the Sears equivalent of the Craftsman screwdriver.
