Had a neo magnet the size of a hockey puck. Kept it inside a plastic tool box with more foam than that all around. The whole box could be stuck to anything!! That thing could hurt you if you weren’t careful!
I did find an ebay seller that claims to sell the correct collet. But don’t want to wait another minute for shipping! Going to convert it to a 3c. Ordered a 3C to 5mt adapter and a draw tube from little machine shop.
Have a HF Vulcan 201 I believe at work. My coworker welded up some aluminum square tubes with it. It was his first time. Actually turned out pretty well.
