This video details program updates from the Sonoran Desert Institute (SDI) at SHOT Show 2026, focusing on a new manual machining course. The course provides students with a Grizzly benchtop lathe for home use, covering essential gunsmithing operations like threading and chambering, alongside hand tool skills. This initiative addresses a growing industry need for skilled gunsmiths.

This video demonstrates the advanced gunsmithing process of modifying a standard Remington 700 bolt handle to accept a target knob. It details the lathework required, including jig setup, interrupted cuts, thread cutting with a die, and the importance of precise gear ratio settings for achieving 5/16-24 threads. The process emphasizes careful machining and finishing to ensure the bolt handle runs true.

This guide details the process of modifying a Remington 700 bolt handle to accept aftermarket tactical knobs, as demonstrated by Robbie Wheaton at Wheaton Arms. The modification involves cutting off the factory knob and threading the handle, typically to a 5/16x24 pitch, allowing for improved ergonomics and faster bolt manipulation. The process requires specialized lathe equipment and precision machining.
