I need some help. How do I Properly prepare my receiver to be sent to Turnbull’s for case hardening. Ithaca boxlock. It was case hardened when new obviously. So, before I polish it should it be annealed?? I know it will polish up but does it NEED to be annealed? Is this to relieve stress and make it easier to polish? I’m just worried about the fit after all this heating. If I have to heat it to anneal then again to have it case hardened. I’d rather just polish it as is and have it colored once. Can you guys help me? Thanks!
