Sorry, I'm not too good at posting pics, yet the pics tell the story better than I can.
My nephew Matt welded up the mill. He did a pretty decent job (helluva lot better than I could do). But one of the sockets, the vertical brackets fit through, ended up out of kilter by a degree.
That caused the bar to bow down at the end, when the clamps were tightened. I actually ripped 2, 6' logs before I clued in that there was an issue, then shut down the cutting until I could get the socket re-welded.
Still, the 372XP ripped through the logs like nothing, with the bar tip slightly deflected. Produced some nice lumber.
The main thing I see right away, is that the sockets should have been raised up about a half inch, above the surface of the mill. That clearance would allow me to raise the whole mill closer to the base, so I could cut a thinner slab.
The way this is built, about the thinnest slab I can cut is 1-1/2". The easy way to fix that now, would be to attach an extra thickness of flat bar along the bottom of the base, to basically shim it up.
After getting that socket cut off and re-welded, to day I spray painted the chainsaw bar tip guard, and then applied caution stickers to it.
