RE: [PSUBS-MAILIST] S201 Plate Type Thru Hull Assembly





That would be easier if the heads are already attached.  I might weld them in with the heads off.  I was copying what I had seen on the S201.  There heads have bolt on flanges on them, so they could just set them in such a way that your not welding over head. 

Do I need two root TIG welds, or just one?

Are you showing the main weld beads done overhead from the inside ? Better to put the main welding operation where it's easier to get to, using gravity as your friend, on the top. Frank D.
