Re: Frozen rudder shaft Hinterhoeller 28
Can you get your trusty sawzall down the tube now and slit that garbage at the top without damaging the lower bushing? I'm thinking if you cut a couple of slots vertically down to the tube wall you may relieve some pressure and then be able to physically remove the two pieces.. at least you'll have some limited space for movement and it may release.
Another possibility, though, if you're ultimately unsuccessful in removing that last bit, would be to cut the existing tube below that seal, then sleeve and extend the existing tube to where you need it.
That said, I do think you're making a bit too much of the job of replacing the tube.. as far as DIY glasswork project I think that's a fairly simple, straightforward task, esp if you can find an appropriate section of pipe or tube for the job. It would be easy to slip a temporary stock up there to maintain the alignment as you install the tube. You'd also avoid any future issues with whatever seized things up in the first place. You could also incorporate a socket for a new lower bushing that might be more easily replaceable in the future..
At any rate you're many steps closer to a solution than when you started... best of luck!
