Newbie diy turntable

rodandgun · 26th May 2009, 03:05 AM

Hey everyone, I've done a good bit of reading on the boards, but this is my first post. Just to introduce myself - I'm a soon-to-be first year law student from Atlanta. I spend the majority of my free time fishing and golfing, but lately I've fixated on audio to keep me happy on rainy days. I have a cheapo sony turntable, 80's JVC amp (hand me down from dad), and some decent klipsch computer speakers right now.

I enjoy woodworking, so I thought my first diy project could be a turntable. The altmann design I've seen looks pretty cool, but I was thinking of taking it up a notch, and drilling the platter and plinth to fill with lead shot. I'm also planning to wrap the plywood body with a nicer looking mahogany.

I'm pretty excited about my first audio project, but I have no idea how to go about getting a motor. I've seen the floppy drive conversion that looks pretty cool. Has anyone tried it? Is there somewhere I can salvage a motor and controller that might be better/easier on someone like me?

Hi Sean,

Welcome to the world of turntables. I too are on the same path.

The altmann design is a good point to start with. What I would suggest is the following:
1. Layered plinth
2. Acrylic/Wooden platter
3. Premotec motor.
4. Silk drive - You can go for surgical suture.
5. External motor supply

Best regards,
Bins.

This one is nicely done imo, I'm currently also looking into a DIY turntable.

I searched around the net for a while, and can't seem to find anywhere to buy a Promotec motor. Can anyone recommend a good vender?

Thanks

Hi Sean,

Try this link from the company site: http://www.mclennan.co.uk/contactus.html Alternatively, you can use a floppy drive motor for the same purpose. Search this forum for details.

Best regards,
Bins.

Hi Sean,

You can get the motor from http://www.rs-components.com/ and http://www.farnell.com/

You can also try out the motor from: http://www.mechtex.com/

Best regards,
Bins.

mclennan are the UK suppliers of Premotec motors, and supply to Farnell / RS.

Their website has a page with turntable motors -
here - or their search facility will turn up some useful stuff as well.

I've seen old reel to reel motors utilized for tt motors.
Or, just score an old empire and get both a motor and a platter...
