Here's a cool project I wanted to share with you. This spring I picked up a beat up Winchester Model 1873 chambered in 44 WCF / .44-40 (built in 1893) from Johnny Dury's shop in San Antonio. The intent was to use it in my gunsmithing courses on lever actions and bluing.




Disassembling a firearm with >130 years old was a challenge. Some of those screws took some heat to get loose.

Once disassembled, the parts were cleaned, sanded, polished, etc. The parts to be color case hardened were then annealed by placing in these crucibles for at 1350 deg F for 3 hours.

Here's the parts post annealing

Polished the brass to a high shine

The annealed parts were then repolished to 420 grit then returned to the crucibles at 1350 deg F for 3 hours. Then they were quenched in icewater. Then moved to an oil bath. The anticipation was high!






Turned out much better than I hoped.
