Ended up with some pretty clean pretty good tolerance 14 gauge mild steel parts today.
I wish I would have took a picture of the back side almost zero dross after the cut.
I use a standard 45amp shielded consumable pack with the settings straight out of hypertherms cut chart.
They use the exact same leaf shape cut the inside for the holes and the outside for a few extra leaves that are going to be tacked on the outer layer. the fit between the two was crazy tight.
When’s this piece gets installed I will post some of those pics too.
