Wondering if y'all know some temperature numbers for the heat treating of barrels, air chambers & miscellaneous parts on Crosman's?
Not sure where it applies, but thinking in terms of re-bluing parts, baked finishes, welding, brazing & soldering jobs at temperatures that might undo factory heat treatment if it exists. One method of blueing is to heat yellow or orange or near cherry red and quench in various types or weights of oil depending on desired finish. Even cold blue is better when parts are heated, but...?
I'm not sure which parts might have been heat treated in the first place except those that are obviously hardened like hammer sleeve etc. Any guidelines in general? No harm no foul? I'm aware of normalizing an entire piece after a process to realign grain throughout, so that parts don't warp, but wondering about those temps also. Suggestions?
Mine are vintage guns from the late 40's to mid 60's.
