SHOT Show 2026 updates from the Sonoran Desert Institute (SDI) highlight a new manual machining course designed to equip future gunsmiths. This program provides students with a Grizzly benchtop lathe and disc sander, enabling hands-on learning of critical gunsmithing operations like turning, facing, threading, and chambering. The curriculum emphasizes the importance of hand-fitting and maintenance for modern firearms, addressing a growing industry need for skilled tradespeople.

Different crown styles exist, but the integrity of the inner edge is paramount.
