Zenith 29JC20 21"--cataract and convergence

[Techguy46]

First big challenge is getting the cataract off the tube (21FKP22). The blear covers all but about the central six inches. I have watched a few youtube videos on cataract removal, mainly using heat. The tube is now out and sitting in the top of a garbage can. The plan is to set it out on a RILLY hot day, then if that isn't enough hit it with the heat gun. (I am in TN, so yes we have days in the upper 90's.) I would appreciate any advice or warnings concerning this operation.

The second big challenge is that the plastic frame for the convergence coils (and magnets) (looks like a 3-leaf clover) is busted in two places, so the coils are kinda ski-wacky. Suggestions for repair? I am guessing something like JBWeld. Or by some miracle are these available? What do I know?

Thanks HUGELY
