Shotley Bridge swordmakers

[urbanspaceman]

I have come up with a design for a machine that can roll hollows into a tapering length of red-hot steel; even one wide and two narrow hollows if required. If I had the right software I could draw it, but alas...
I keep going on about the waste of grinding, but this machine could first roll the majority of the hollow, then grind true, then polish, just by changing the wheels and the speed. Including the Colichemarde!
