Small Diameter Round Turntable Belt

Good evening all,

Can anyone suggest where I might purchase small diameter round turntable belts? I have gone on the internet but have not been able to locate a belt for my DIY turntable. If I find a source I plan to purchase 2 or 3.

I have purchased belts from "Turntable Basics" but they are too large and not very pliable at that. I am also looking for a source for flat belts for my other turntable motor. Belts should be 21 inches or in that vicinity. If I am provided a source I would certaily be grateful. Thank you for any feedback.

NeedleDoctor helped me with a odd sized belt I was looking for. They answer the phone, which not that common anymore.
Caution with belts, I bought an Thorens 160 S for my son with an old belt. I also bought 4 different belts with the
intention to 'improve' the TT. I also discovered that the belt of my Kuzma Stabi Ref. 'fits' qua length but only the
old and worn out belt 'got' the platter at 'just speed'.
I had no idea that also regarding such one 'miserable' part 'everything matters'. So I got engry but the Thorens was not impressed. I know that my 'proof' by induction is not very impressive also but I hope that you will not end with 5 worthless belts.That's why of my warning.
This is a great site with reasonable prices.
Good afternoon all,

Thank you so much for your input and assistance. I very much appreciate what you've done for me hear. I will follow up with your information. Thanks again.
