David:
The two springs that I measured from an Elgin 18S were 0.020 and 0.025 so it looks like that mix of thicknesses will work pretty well for something a little larger and several sizes smaller. However, what about the steel – “Blue Tempered, Polished Finish, AMS 5122, SAE 1095, AISI 1095”? Does that sound about right to you?
Thanks!
Tom
