This video shows how I build a punch tool for my new LED wall where I have to put in 1200 holes into sheet metal. The punch is made from mild steel and involved lot's of sawing, drilling and welding and other machining. I finally made some progress with TIG welding and share some tips that might help overcoming beginner struggles. To be able to aim where the holes go I added LED projected cross hairs.
It's tested and working with 1mm aluminium so far. Enjoy!
