Thanks for reply Dunemaul. Most of my steel is sheet steel or light steel tubing. Havent come across any angle yet, but I am only doing about 5 hours a week right now. I hope to devote more time as wife is out of town and I have had to take care of 3 kids last 2 weeks by myself. She was not happy when I called her to tell her I was going to give this a try, but after first load she gave me go ahead so I will ramp up my efforts upon her return.
