Cheating on a DIY turntable

arnoldc · 14th August 2007, 01:11 AM

Here's my DIY turntable prototype using parts left over from a previous upgrade.

The pulley size isn't optimized yet, and I need to have one custom made.

I also want a 1" thick alumimum as the plinth for this project. I aim for 2-arm configuration.

Nice,
Im already planning a DIY TT using my SME 3010R arm.
Can you tell me more about the motor you use?

The motor is a floppy drive motor

Effortless to turn the platter. Check the AudioOrigami website for details. Mine is a Sony branded one.

It seems that the floppy drive project in the audio origami website is no longer available!

Is there another place where I can find it?

Thank you Nanook!

Is this floppy motor capable of turning a 3 inches acrylic platter?

And how is it possible to do a good quality bearing?

Hi Leo,

Th floppy motor (at least this one I used) has lots of torque. It can spin the heavy TNT composite platter without any effort.

For the bearing, there's a post here on how to use Harley-Davidson parts to make a bearing.

Does anyone know what brand of floppy drive this is?
Every one I've tried has some opto switch to sense the disk. In addition I could not find the resistor to adjust the speed. One like this or similar would be just the ticket.

look at the link . A discussion on defeating the opto sensor is in there, as is the process for determining the resistor value/ pt to tie into.

c'mon guys. Read the link, then ask the questions

A DIY could be made from a discarded VCR head/bearing assembly.
