Parts needed for winch mount Pre-runner tube bumper:
2 or 3" Sch 40 galvanized pipe (Main bumper bar) (stronger than black pipe, cheaper than tube)
2 or 3" .125" wall, steel HREW or DOM tubing (HREW costs less, and is more than adequate. All tube weighs less than pipe.)
1.5" or 2" Galvanized pipe
1.5" or 2" HREW or DOM .125 wall steel tube (upper hoop)
3/8" thick steel strap, 2" wide, for mounting the bumper, six points on frame
Required bolts (3/4" Grade 5 or Grade 8, or metric equivelants)
1/4" plate, for mounting winch.
It'll be around $200 in material for a prototype, but the material cost will be greatly reduced w/larger numbers. Sell them painted, or unpainted (powdercoating is the expensive part, I'd stay away from that, except as a special order, which will generally run the customer $150 extra! If group buys on powder coating, the price drops, as it's charged per lot, not per part). Labor will reduce w/larger volume too. It's still less time to build, than a Bull bar type bumper. Plus, EVERYONE makes bull bar bumpers! Dare to be different!
