Cutting Keyways in a GIANT Sprocket

About

Topper Machine LLC may be closing as a full machine shop after 13 years, but the work continues. I’m still restoring classic machinery, helping the few loyal customers I have left, and filming every project I can—because I’ve always been Too Dumb To Quit. This channel is dedicated to high-quality mechanical restoration, machining, welding, and fabrication. You’ll find dragline crane restoration, tractor rebuilds, steam engine restoration, sawmill projects, metalworking techniques, equipment repair, and old-iron preservation. My goal is to keep mechanical history alive by documenting real-world machining and fabrication work, showing how vintage equipment can be rebuilt, restored, and returned to working condition. Whether you’re into machining, welding, heavy equipment, or historical restoration, this channel delivers hands-on projects and authentic shop craftsmanship. Subscribe to follow the journey and support the preservation of mechanical history.
