Welding Positioner

I like it BF. I have a simple one, made out of a gear reducer and gear motor from a blue print machine. Does the sprung ground strap carry the current well, ingenious idea. Been wondering how to make a slip ring for my next generation one. Would like to add a carriage for the mig gun with a power feed to build up shafts.
Now get that thing painted so I can carry on with mine !!!
