Building the Horse Shoe
The main ring is made from two pieces of 50x3mm flat steel bar and bent on a roller for curving steel and then held in a jig, brought up to a hot temp (nothing too accurate I just used an oxy flame reduce heating a cooling flexing) and welded with a 6mm gap between them to improve stiffness.
The photo is of the early stages of construction and testing but you can see the ring more clearly with the primer on it.
The band drives were the next challenge.
