Just as the central braces can be your own design, not all ladder bars need to have straight bars. The CCHR crew also builds versions that have curved ends more in the style of a front hairpin, though we've shown their usual style being made. Here's how a pair of hairpins, with those curved ends, are fabricated, using a temporary jig. A length of angle iron and a section of tube were welded to the table as shown. Note the tubing which will become the hairpin is marked to correspond with a mark on the tube former (arrows), ensuring each section of the hairpin will end up at its required length. It's then tack welded to the angle to keep it in place.
