First I use this to cut 16 gauge sheet steel. When I first used this I was really annoyed, the cuts were jagged, jagged, nowhere near the actual cut. Traces and the metal I cut kept moving, the secret is to put the metal in a vise and use the jaws of the vise as a guide. still), press it against the desktop and cut it horizontally. It gets the job done and I like it as a cheap solution for cutting thick metal. that works great
