I would build what I need if it wasn't for me not having a decent 220 mig.Nope not a tig,just a good penetration 220 gas mig.That is the hold up on so much I would do.Recently I have been thinking about a used tum-stone Lincoln stick welder just to get me started on some of the stuff.I know alot of the plans is on Allmetalshaping from Kerry Pinkerton.Right now all I have at my shop is a 110 gas mig which works well for sheet medal fab'ing. Kind of frustration cause I do have a bunch of ideas................
