Iplayfarmer, If you want the proper professional tool for cutting a straight line with a torch. It is called Contour Curv-O-Mark Model 28 Magnetic burning guide. It is basically a "raised" straight edge with 3 strong magnets underneath and offset a little. There are additional aluminum angle pieces that you can purchase that bolt to the top which increases the total lenght. I used/borrowed one once to cut out pieces on 4' x 8' sheet steel. That next week, I was on the Internet and bought my own. You still hand cut with the torch, but it works so much better than angle iron because the straight edge is raised about 3/4" to 1" off the plate steel. I sometimes wonder if one could bolt some horseshoe magnets underneath some 1/8"x1 1/2" angle iron and maybe accomplish the some function. I barely had to grind anything off compared to when I try freehand or clamp angle iron directly on top of the steel. Airgas, Inc. sells them or do a google search.
