Key question... is the CT already welded onto the
hull? If no, you need to find someone with a really big lathe. It yes,
well... big job I'm afraid! I think Greg Cottrell told me he'd
corrected this situation with nothing but an angle grinder, flap
wheels, and several hundred hours of patience. I had the same issue
with a penetrator bulkhead seat, and I "machined" it by making
a custom tool. I took a cutting tool off my lathe and put it
on an adjustable radius arm, which had a base that jammed into the opening.
Then I just went around and around by hand. Got some good blisters, but it
did the job. That was for a little part that's only 7" in diameter, but
perhaps you could make its big cousin. Motorizing it would be a really good
idea.

Hi All
I need Idea's to get my ct ring surface to mate
with my hatch ring as it has warped by + - 2mm in the welding
process.
Thanks Glen
