mrpete222 is the channel of Lyle Peterson, a retired shop teacher from Illinois in the United States who also goes by the name tubalcain. He has made around 950 videos on machine shop work.

The videos teach how to use manual lathes and milling machines, along with foundry work, model engines, antique engines and tractors. There are also regular mystery tool videos, where viewers guess what an unusual old tool was used for. He explains things the way a teacher would, step by step and with patience. The style is traditional and unhurried, and many projects run across several episodes.

mrpete222 is a good way into mechanical and manufacturing engineering. Machining is how many metal parts are made, and understanding it helps engineers design parts that can actually be produced. It connects to engineering apprenticeships, toolmaking, maintenance engineering and mechanical design. His teaching style makes even unfamiliar machines feel approachable for complete beginners.
