Is there a company or anyone who has the appropriate centering tools and bending machine to completely straighten a bent motor shaft for TD 160. Small shaft with clutch.
TD 160 Bent Motor shaft

We used to do that on a Lathe.
Chuck up the Rotor, Set up a dial indicator then bang the shaft lightly with a piece of 5lb brass round stock.
Worked perfect.
How did it get bent?

usual reason is the post that prevents that is missing, or its an early model that didn't have it and the platter bounced for some reason. At some point one of those motor mounting screws got swapped from a regular old screw to something thats taller than the top of the motor pulley to prevent this.
bad shipping will do it even with the post. if that outer platter shifts over it will just whack the motor.
not sure if you've ever done a Thorens motor specifically but its a pretty weenie motor, 5lb is probably a bit much. Not quite motivated to measure mine but I doubt that motor shaft is 1/8".

Op can also purchase a motor protection post from vinyl nirvana. Highly recommended for early models.

Thanks for the replies. I will contact Vinyl Nirvanna. I tried the self straigtening with repeated marking and tapping with a dead blow mallet. I got it pretty close. I would like to get it with no wobble at all, and I'm worried about damaging the bearings. It seems to be an older one (Just bought it on ebay cheap from Canada) They shipped it without securing the hold down screws and the platter most likely messed up the motor shaft. It doesn't have the tall post like my other one from '73. Addittionally, the tone arm was pretty messed up, but I'm pretty sure it can be restored. It didn't get bent, but the set screws that hold it in were missing and it was just "floating" around in the packaging. Gives me something to mess with for a month or two in retirement.

vinylnirvana.com seems to be a dud. They do not have a valid email address.

that is NOT a repair we do. Sorry, you are left with DIY...just get it best you can and leave it.
I wouldn't recommend a mallet, too risky for the bearings. And these motors aren't easily taken apart for putting the spindle into a lathe (good idea for other motors). But I've previously written about how I've done it, starting here: https://audiokarma.org/forums/threads/thorens-td150-td150-mkii-or-td160.976399/post-15169608.

That email address does not exist, at least according to my gmail when i write to it. It just returns an error message. Also, any of the other prompts on the site take me to a phishing/malware adventure. I'm going to keep playing with it since i have it to within a fraction of a mm.
That email address is from vinylnirvana's website and works fine for me. Also, Dan (ddarch), who is vinynirvana, responded to your posts.
This video goes into it in depth -
Great video! Thanks!
Just a little trivia question. A guy I knew a long time ago had a TD-125. And if you pronounced "Thorens" THorens, as in "them," he would go absolutely ballistic and spend the next five minutes telling you why it's Thorens, as in TOR-ends.
That has stuck with me for all these years. I have no idea which is correct.
It's ok to pronounce things in your native dialect. This isn't National Public RadioGreat video! Thanks!

Don't tell that to that particular TD-125 owner. And he wasn't Germanic either.
I think his ancestry was from Southern OCD.
BTW... his favorite LPs were the Carpenters. That's all he played, at 96dB! It took me a long time to be able to listen to any of their tunes again.
The guy went on to be a surgeon. So you get the "OCD."
I'll offer an opinion here and being from the old country, Germany to be precise, I CAN tell you that any word beginning with "th" that I'm aware of is pronounced with a "silent" "h" and therefore "Thorens" becomes "Torenz," but I'm pretty sure I know someone who can clear up any remaining doubts......hello Manfred @lini? Meanwhile, as we and other countries will typically do, I'd say pronounce it as you like and what makes sense to you in your most familiar vernacular. But it's a good question, @Mr Boochie, and one I'm confident a fair number of others may have asked themselves as well. Carry on, amigos......
Thanks! All I know is that in that guy's house, you were in Deutschland! I ended up pointing to devices and calling them "that" or "this" just to avoid the linguistic lessons.
His Dad owned a Porsche 911. We won't even go there, with all the proper Teutonic phrases...
