🔩 I Turned a Simple Bolt Into a Precision Spring-Powered Center Punch
Most people see an 8.8 bolt as scrap metal. I saw a powerful, precise, spring-forced center punch hidden inside it.
In this video, I transform a single 8.8-grade bolt into a fully functional spring-loaded center punch using only a drill press turned into a lathe. No CNC. No fancy machines. Just creativity, precision, and hand-made engineering.
This center punch works with a pull-and-release mechanism — pull the body back, release it, and BOOM — a strong, clean, perfectly centered mark every time. It’s compact, powerful, and incredibly satisfying to use.
