I used this roller to make a grill stand and a couple of other items. I rolled 1/4" round rod and 1"x 1/8" flatbar. It works great and is eay to use. I locked it into a vice and used it from there. I wish they made 3/8" rollers for it as I feel the machine would be more than capable of the thicker stock. I have no complaints with this purchase and would recommend for small home and ornamental projects.Robert H.
