Midwest Radio Symphony Grand Turntable Restoration Part 1

Produced with CyberLink PowerDirector

[@DavidTipton101]

Well done getting the original turntable Vern and two thumbs up to Mike for getting it for you 👍👍 I was going to suggest a square section O ring but you covered that. I will always get a comment saying the diameter of the idler wheel will affect the platter speed. I usually reply after a long exchange, if you have two pulleys driven by a belt and you increase the distance between the pulleys and fit a longer belt the pully speeds will remain the same. Good explanation from you 🙂

@@DavidTipton101 hi david, I figured I better nip that one in the bud and save myself a lot of typing later on.

I like the way you go about thinking things out loud to us Vern. We should all have a healthy internal conversation every now and then. No this video was NOT too long by any means.

Great job explaining Vern, I have commented before, on your restoration of the Midwest, I have almost the same cabinet and radio, I believe the one I am attempting to restore is a 1950 model, the phonograph is very similar if not the same, I can email you some photos of that, like you were wanting. I actually did plug it in when I first got it and it did work, but like yours the cord was dry rotted so I didn’t run it long. Reply back if would like the pictures of that. Thank you sir.

Thanks for watching and for the offer. The only thing I am trying to determine is if there is a hair spring (coil) around the post I pointed out in the video. If there is, a couple of good photos from different angles would be great so I can recreate it. If there isn't any spring there no need for any photos. The Sams Photofacts for the turntable does not show any detail there. I am just not sure if it is supposed to have one or not. Works without one, but again I don't have any 12 inch records at present.

It does have a small spring I can take some pictures of it for you

@@jdssmoothiechannel8892 I thought it must. My email address is on the front page of my channel. I'll have to order some spring wire and make one.

[@jdssmoothiechannel8892]

Upon looking at it further, all the springs are there, the spring on mine is a little wore out, but still works, at looking at yours on the video, the spring looks to be wore out, or not as tightly wound. Metal fatigue from being 75 + years old, maybe? I did get some pictures, but have not located an email address on your page. I will continue to look, however.

@@jdssmoothiechannel8892 Hi JD, What I am referencing is the small groove I pointed out with my pencil. In fact I placed the pencil tip into the groove. This is where I believe there should be a very small hairspring coil. I have actually ordered some spring wire which should arrive today and I am going to try making one. email is [e-mail]. Thanks for your help.

That mechanism needs the leadout grove to move the tonearm back and forth to trigger the return cycle. Just holding the tonearm at the inner position isn't going to trigger it. Notice how quickly it triggers when played on a real record.

@@geirendre I figured that out after playing with it for a while. But thank you
