It's easier than you think to make a sweeping bend in your rectangular tubing- these frame curves from Welder Series let the home builder produce a professional looking chassis without expensive machinery. All you need is a welder!
Designed for rear kickups, center sections, frames, etc… perfect for builders looking for a smooth bend in either direction that doesn’t require special machinery. Available in 2"x3", 2"x4", and 2"x5" sizes. They are shipped in four pieces as shown. Because they’re made from 3/16 (!) steel, when you grind the weld it will match up with the corner radius on hollow structural tubing.
There are no kinks or stretching normally associated with mandrel bent rectangular tubing, especially being bent the “hard way”. Reference tabs let you clamp the pieces corner to corner while they’re welded. There are scribe lines on the top and bottom plates at 30 degrees, 45 degrees, and 60 degrees so they’re easy to cut and replicate side to side.
