[PSUBS-MAILIST] K-250 Hatch Dome Removal Question

[Steve McQueen via Personal_Submersibles]

Hank, the dome has no life left so I can bust/cut it out with a hammer,
drill or a chainsaw if needed.  I tried the blade idea but not much luck.
I only wanted to keep it in 1 piece as a reference for my new dome. It
probably isn't needed even for that.

I have been reminded my hatch ring is what I need to protect and therefore
heating might not be a great idea.
