[TheForge] Air hammer return stroke

[Phil]

I used an automotive valve spring the first time (1972 small block chevy) and it started to lose it's "spring".  I found some die springs in the McMaster Carr catalog and they work great.  They are a little more heavy duty, and you can get them with various inside diameters, and heights.
