All right, moving on. For today:
I've only ever made bridges out of round tubing, but I thought I’d try something different on this little bike. I like the look of the plate reinforcements I’ve seen on a few different mixte-style bikes. So, I decided to ditch regular, round bridges all together and purchased some 4130 sheet steel from Aircraft Spruce.
I started with poster board (actually, this was a manilla folder that was within arm’s reach). I traced and trimmed until I had the pieces and shapes that I was satisfied with. Then I transferred the shapes on to the steel and cut them out with a cutting wheel, cleaning them up with files and checking that they fit well.
