I need a rear bumper for my woodhauler-the old one literally rusted in half. State law says I need some kind of rear bumper and the truck is due for inspection by the end of May. I have a lot of steel that I've gathered over the years as well as a stick welder which I'm reasonably proficient with. What I don't have is any type of heavy duty cutting tools such as those mentioned above. I'm looking to build something very basic like this: I have two 8' lengths of 2" x 5" x 1/4" rectangular channel, one of which I'd like to cut down and use as the rear piece. I'll have to sort through the pile and see if I have anything smaller for the corner and side pieces, but the big question is how to cut this stuff? I considered purchasing this angle grinder: http://www.harborfreight.com/4-1-2-half-inch-angle-grinder-95578.html?ccdenc=eyJjb2RlIjoiODE0MTM0NTEiLCJza3UiOiI5NTU3OCIsImlzIjoiMTIuNDkiLCJwcm9kdWN0X2lk%0D%0AIjoiMzIzMyJ9%0D%0A from HF (on sale for $12.49!) along with a lot of discs. Grinding through 1/4" steel won't be much fun though. Anyone have a better suggestion?
