Zach's sissy bar is pretty much finished - save for the mounting lugs for his fender. Part-timer Steve thought we should give it a little bend at the top, and I agreed. I also added a 1/2 turn twist to the crossbrace before I welded that in. Maybe people will notice it, maybe not. I think Zach'll be happy with the results.
The bar's overall height wound up at 27", and took 5' of 1/2" hex stock to complete, and when I trimmed it to length, I had a 1 1/8" piece from the left leg, and a 1 3/16" piece from the right leg left over. The crossbrace was a piece of hex that came out of the scrap bucket. You know the old adage "Never throw anything away....".
Like I've said, I don't use jigs, don't use outlines drawn on the shop floor, welding rod patterns, etc - just a centerline mark before I bend the material in half, and I use a few well-placed measurements and soapstone marks to get my bends in the legs to fit the fender and frame dimensions after that. Plus, a few tricks I've passed on to Steve about bending and forming sissy bars, but he still can't snatch the pebbles from my hand - "Hit me with the broom, Grasshopper......". His time will come.
