Refurbishing my old Diy Turntable

[joschi63]

Hello I am new on this forum. I have this DIY Turntable I build 30 years ago. Then I moved a view times and it vanished in a box. Now I want to rebuild it up again and make some changes. Not so much in the design more technical like magnetic bearing and change the motor. I used an Thorens synchronous motor which was far too weak. Last weekend I put the parts out of the box measured them and mad some CAD models. Her is what I came up with and I hope my old turntable will look similar to this when I am ready with the project. I can take some pics of the status quo if interested. Hope I get some feedback and advice from you.

Looks gorgeous! Looking forward to seeing the completed new one. Good luck!

Hi, No good reason why a Thorens motor would be "far too weak", rgds, sreten.

Looks very well made. After fitting magnetic bearing wouldn't it present somewhat lower load on motor so as Thorens motor can be used ?
Regards.

Hei, thank you all for replying. My plater is about 5 kg in comparison to 1.5 kg the platter of an Thorens. It needed always a helping hand for getting the rotation started. I am going for an BLDC solution. I thought about buying the motor from Jasmin Audio, because i take me to long research to come to solution. But i build my own housing around it. Hilsen Joschi

Not finish jet, but it turns

Have to to put paint on the subframe and mount the posts for the tonarmefixation. And more...

That's a nice looking table. Following.

Put some paint on the subframe

Thanks Vin! Put paint on the subframe and made a cut out to get the drive closer to the platter.

New Pics

I am getting closer. Have some problems with testing lubrication for the bearing. Found very different opinons in forums, was not very helpfull Will do some more tests the next days. Magnetic vertical bearing works fine.
Still a lot to do!

New mounts

Made new mounts in stainless steel instead of brass. The mounts are hollow. They will house a part of the suspension.

Finish

The turntable is finished. Wating for new cable's for wiring the tonarm.

Reply

Since I am the nearly the only one who replied on my thread it make no sense for me to go on with it. In the beginning I thought it might be an interesting project not just for me, since this is a diy forum. It's not that I am dissapointed, because I had wrong expectation. It is just boring to answer your own thread.

Nahhh!
Ok, just one hint: put the cables outside the ( hollow) arm !
The movement will be much more...relaxed !

( just use some very small solid core enamelled copper wire )

 

[picowallspeaker]

I guess you can do much better than me !
I also made the headshell tightly attached with glue to the arm..

Wiring

Thanks, but i prefere to guide the cables through the tube. Ordered cable with soft insulation. Have already deassembled the tonarm. Also a good chance to clean everything up and adjust the bearing when I will reassamble the arm.
