easy to make your own custom long bits, I've done it many times. Take a piece of cold rolled rod of the correct diameter, backbevel the rod a bit, clamp pieces to piece of angle iron, quick spot heat with torch to bump temp to 200-300 degrees,doesn't take much, tack, quickly rotate 180 and reclamp and finish weld & cleanup. Don't quench, let cool slowly either by sticking in sand etc The whole process takes less time then it takes to describe it. If you want you can let it cool a bit and then do your cleanup using something like a 80 grit wornout flap disc so you are actually pushing a bit more heat back into the welded spot so in effect it gives it a post heat. Just takes a few minutes to do but don't skip the pre and post heat. Bob.

bob-Thanks for the description of that process. I've often thought about learning some basic blacksmith skills. Maybe someday in the future.
