Yes. The pics are a little outdated, but they show the design. I've made a few upgrades, but they don't affect how the system works.

Not a problem, your machinest most likely has it on hand as it's a commonly used item to begin with, and he'll know how to work with it. The stuff I get is easily cut/machined before hardening and tempering.

If not...316 stainless is a decent substitute.

Saefroch...hardening and tempering are different processes and should not be confused. This is basic, but was found quickly..
