Greetings all;
After 6+ months, gun farts has not shipped the magazine spring I need to
finish the conversion to a smaller cartridge in old meat in the pot.
This is a flat leaf, bent in the shape of a W. S/B nominally 1/2 to 5/8"
wide, folded at 3 places around a 3/32 drill shank. What spec of steel
do I need? and how do I heat treat it to put the spring into it once its
been shaped/bent properly?
Blued steel carton strapping is about what it should look like and its
about the right thickness, but that stuff is pretty soft, and I doubt it
could be hardened enough to make this.
Thanks all.
Maybe anneal, bend, harden, and blue temper a mainspring?:

or add carbon to the shipping strapping:
