I have a Scott tuner with a slightly bent tuning shaft, does anyone have a suggestion how I might straighten it? Thank-you.

Hi Fred, check your PM. - Dean
A picture would help. Is the flywheel removable? You'll almost certainly need to remove the shaft from the tuner to work on it safely. That probably means re-stringing the cord, so be sure you're ready for that. Straightening the shaft will probably require a couple wood blocks and a vise or large hammer. Avoid the urge to just hold and bend it directly with metal tools like pliers or vise-grips.

This is a picture showing the shaft.
Looks like the tuning vanes are bent on 2 gangs. Actually looks like they are shorted to the other fixed vanes, a no-no.
Turn the turning dial all the way the other way to expose them. Then bend them back, carefully, one by one. You want them centered between the fixed vanes as much as possible. Use a flat, wide strong tool on one side to bend them back. Like a putty knife/scraper or drywall tool.
You may need to re-align the tuner for best results, but it should be close if you can get the vanes centered again. Also clean the center shaft contact points with de-oxit or equal, but take care to get nothing on the vanes themselves. They must be clean and dry.
I would explore all options trying to repair this in place before trying to replace it. They are easy to find, but would involve a lot of soldering and absolutely require a full front end alignment after putting another RF front end in. Almost all the Scott tuners from this '58-'64 or so era used that exact same silver plated 3 gang front end.
Well, that's not what I was thinking of. That's the tuning capacitor itself, unless the large shaft on the left is an outer tube that can be removed. It's been too many years since I worked on one of those tuners, I don't remember the exact mechanical arrangement in that area. Sorry I can't be more help.

Thank-you for spending the time looking. I would like to start by removing and inspecting the inner shaft. There is what might be a cap over the end, but it would be nice to know more about it before trying to pry it off.
You maybe better off looking for a parts-out Scott & pull its variable cap to replace yours. Not sure how good the reception will be with that bent shaft, even after tweaking it.
Thank-you for the suggestion, I have been watching the auctions for Scott tuners with vernier tuning. Speaking of which, can anyone explain to me how the vernier is implemented? Is it planetary gearing at the end of the shafts?
