Looking for a round belt ideally 2-2.5mm thick to drive a 310mm platter has proven to be more difficult than expected. Or maybe i am approaching this the wrong way.
The flat belts that fit my platter are about 1020mm long so i assume a suitable round belt should be of similar length. Haven't had much luck finding one so far.
1. Acoustic Signature seems to offer two belt sizes for their subplatter and circumference driven turntables, correspondingly 490mm and 900mm. 900mm is less than the circumference of their platters, does that mean their belts are very stretchy?
2. Project offers a lot of belt sizes and shapes for their turntables. They do not disclose the actual sizes but it seems the longest is 97mm (RPM10 perhaps). The thickness still remains unknown but from the pics it looks very substantial. Project also sell 3mm pulleys, some of which perhaps fit their own belts.
Project belt resellers in general seem very reluctant to supply Project belts to other turntables. Belt sizes appear to be a carefully guarded secret.
3. VPi?
4. Clearaudio?
5. Others?

Try an O-ring seal, not the sticked one, you can find them in a lot of sizes at a bearing shop.
Splice a few sewing machine belts, or a meter of O Ring
Buy excess quantity of it, to experiment.
Get synthetic rubber like nitrile, more durable.
Cheap here, 30 cents a meter or so...

+1 for McMaster Carr, and not just for the belts/O-rings. Browse their inventory (or request a free catalog) and you'll find solutions to problems you didn't even know you had 😉

Belts are available on fleabay.
I ordered some extras for VPI based tables, but haven’t needed to use them yet, from this seller who has good feedback.

No specifications on belt profile/thickness…you’d have to ask.
I get the impression he is making them himself from a reel of material. Custom lengths may be possible.
There are other sellers as well.

Of course he is.
Experience with flat belts has taught me there is a substantial audible difference between a generic and a specially manufactured belt such as the ones made by Origin Live. Material, uniformity, surface treatment...
I guess i would just have to buy a few round belts and try them out.
Like I said, get proper extruded rubber cord, it is about 50 cents or so per meter here.
Molding a piece of rubber means you have to spread compound in the mold, and heat it up, then remove the flash....injection molding is also possible for that item.
But 1 meter long / pi is about 160 mm radius, you need a diameter of 320 mm, and a larger plate size.
That is a fairly large mold, I wonder how many people will make it for you, because in a small run at least 4 of 10 will be scrap.
The best and reliable solution is a spliced O ring cord.

Bike...electric scooter inflatable camera and good quality scissors.Bike repair shops have tons of defective ones that have been changed.Someone needs to just pass buy and ask when they are going to bin them.

Had the same problem a while ago, and ended up with 2 set´s of belts for EAT Forte = 2 belts, same size.
Or you can choose EAT Forte S with 2 different belt sizes, depending on the distance to your motorpod.
EAT
Give Jozefina a call, and she´ll recommend "a retailer near you" 😎
Sorry for mixing this up. Forte = different size belts.
Forte S = same size belts.............. 😉

Thank you! Completely forgot about EAT.
Here's Fremer taking a lesson a few years back. Tried focusing on him but my finger slipped.

Laying it "double", it measures approx. 91mm in length. The diameter/x-section is 2mm 😉
This is for the Forte, which i bought. Don´t know the length of the Forte S. Platter diameter is 310mm.

Bought belts for Forte. Unfortunately they are much longer at 140cm as on would surmise from the monstrous platter they drive on the Forte. Unusable in my case.
In the lack of other suggestions Project seems to be my next stop.

Ask Mr. Biermann from magaudio. He is making customized round belts.
I bought several from him.
