Next up was the barrelled receiver.
After cleaning the receiver by soaking it in acetone and scrubbing it, I rinsed it with denatured alcohol. As with all other parts, once it has been cleaned, it cannot be handled with bare hands.
As I do not have a heat source large enough to heat it, nor a pot large enough to boil it in, I had to improvise.
I would heat the receiver and barrel with a propane torch - just enough to get it over 200 degrees.
To boil it, i picked up a 4" piece of PVC pipe and capped one end off. As I was heating and rusting the receiver, I had a few pots of water boiling.
I set up some wood slats on a rubbermaid trash can as a working platform, and got everything in place.
After heating and applying the rust blue solution three times:
After the third rusting, I started boiling
As the pipe was not long enough to do the whole assembly, I had to do it in phases
Barrel down:
Receiver Down:
After repeating the process four times, I rinsed the assembly with a clean pot of boiling water, then heated it with the torch to remove any water left in the receiver.
I then applied oil while the assembly was still hot. Since I did not have enough for a full soak, I stood the assembly up and propped it against the wall, and drizzled oil on with an applicator brush.
Next post: Finished.
