Mr. G. Brettin's Slow Motion Leg Hump

gbrettin · 04-28-2025, 10:52 AM

Picked up a new miter box and got to work finishing the cold side piping. I must have actually learned something over the years, because I knocked it out without a single miscut — which still feels a little wild, honestly.

My goal from the start was to avoid pie cuts, based on some past lessons learned. I pushed both pipes out as far as possible to the sides to mirror each other. Packaging constraints were dictated mostly by the alternator location and the swirl pot. Ideally, I would’ve loved to tuck the pipes tighter to the frame, but moving the alternator or swirl pot wasn’t an option (hard no).

Each joint is cut to sit perfectly flush so the welds won’t pull the tubing around — another lesson learned the hard way from past projects. It might look simple in pictures, but it doesn’t take much to mess up angles once you start stacking cuts.

The end result?
Basically a giant chrome handlebar mustache.

Both pipes were dropped off to get welded at Auto Dynamix in Kalamazoo, MI (local performance shop)
