Before i bought a mig in the eary 80s we welded sheet metal and exhaust with torch and coat hangers. Coat hangers were very valuable and late at night hard to come by. I can remember looking in the closets trying not to wake some one looking for a filler rod.When my brother started racing he bought wire at the hardware so i could weld the doors shut. Me and a buddy bought and split 59 pounds of coated brazing rods. I thought that would be a life time supply but they were used up 20 years ago.I have forgot alot of stuff so i have been practising.
