Guys, just completed an ugly turntable here...

I'm using a floppy motor and belt drive.
Do you think I can use the floppy disk as rim drive for this turntable?
An externally hosted image should be here but it was not working when we last tested it.

pretty ugly to me too....
nope!
actually looks quite nice. What arm?
if the ratio of belt pulley diameter to platter diameter remains the same, then no problems. a way to adjust the tension between the platter and the drive wheel may be neede or an idler wheel.
Bearing details?

Hi Nanook, thanks, but I cheated 🙁 The plinth is from an office desk. The bearing and platter is from my old Clearaudio Champion. The arm is an Eminent Technology ET 2.0
I need to research on idlers... I hope it works. The floppy motor is very good with the belt drive, no stress to turn the platter.
The calculated pulley diameter was 33 1/3 * 29.8cm / 300 = 3.31111
So if I can find an idler wheel of that size, then I'm good?

Have a look at the new Teres rim drive. Verus I think its called. It might help you out, but I think you would need a way to control the speed.
But I have to ask. Why would you take apart a clearaudio champion?

ya, I'd ask too, unless the motor was pooched.
Hmmm, an Altman bearing with a floppy drive and a plastic wheel or direct to the platter.
here's the really cool thing about idlers. any size will do as ultimately it is the "linear" speed of the motor that determines the linear speed of the platter. The idler allows some isolation, and a means to adjust the tension

Oh, the bearing and platter were "left-overs" from my upgrade to the Champion Magnum (70mm vs. 30mm platter and new Ceramic Magnetic Bearing). I'm just trying to put them to good use 😀
I've seen the Teres rim-drive yesterday... Pretty expensive!

Altman bearing....
A Harley Davidson valve, and valve guide. A steel ball bearing and an end plate.
Altmann DIY turntable
Have a look. And his DACs have been very well reviewed🙂

Hi,
Can someone tell me the maximum platter weight that can be driven by the floppy drive motor ? ( Will it be able to drive a 2 kg platter ?)
Regards,
Bins.
