That is so kool!!!
My nephew was up from Portland one weekend -- and during a "shop tour" he expressed a keen interest in doing something. So I fired up the plasma cutter and had him build a "sun flower"... they could take home and put in the yard. That made for LOTS of practice with the plasma and to make the "seeds" -- lots of spot welding to make bumps... and to weld all the pieces together. He loved it! Maybe I created a future hot rodder. LOL
