This video details the repair of a Harley Davidson motorcycle engine case, specifically addressing a damaged and "wobbled out" cam hole. The process involves glass beading the case, welding the damaged area solid, and then using an end mill to precisely counter-sink the hole to the correct specifications for a new cam. The technician highlights the use of a specialized fixture for accurate measurement and dialing in the counter-sink depth, emphasizing a tight press fit for the final installation. The entire repair is completed within a shop time of forty-five minutes.
This video tutorial demonstrates how to repair a bent ejector rod on Smith & Wesson revolvers. Larry Potterfield, Founder and CEO of MidwayUSA, guides viewers through the process, starting with the disassembly of the revolver to remove the ejector rod. He then uses a drill press with a dial indicator to measure the rod's runout. By carefully tapping the rod with a nylon-faced hammer, he realigns it to eliminate excessive runout, ensuring smooth operation and proper ejection of spent casings. The video concludes with the reassembly of the firearm.
