This saw works extremely well for cutting 2 X 3 X .120 wall tubing and 1 1/2" square tubing w/.120 wall. I've also cut other solid steel stock with no problems at all. Also, this saw has an acme thread which is what you want over a standard thread. I also added a few drops of oil onto the threads to prevent galling. I used a small square to make sure the jaw was at a right angle to the blade because the movable spring-loaded pin has too much slop in it to repeat correctly. Other than that I have no complaints and I'd buy it again. This bench is 12 feet long, TIG welded with the legs painted silver and top painted teal color.
