Default Congratulations

Good morning Records33,

that looks migthy impressive !
Can you give me some data about the weigth of the flywheel, the weigth of the actual platter (of the record player) and the size ?

And what is the exact purpose now: just for sharing this mouth watering execution of a flywheel or.......is it possible that we can "buy in" in this project ?

Currently my 17 kilogram platter is driven by a minute motor. The bearing and weigth of the platter make it serious stable. That is why i don't want a torque-heavy motor....it is so dominant....it will present itself (in the platter). A flywheel is a very good solution to detach the motor and platter. So i would be very interested.

Included a picture of my current record player consisting of a oversized 50 centimeter platter (Scheu) with a diy tonearm (more than 17" !; based on a WTA).

Once again congratulations; and i will follow this thread closely.
Regards,
Reinout

Hi, travel for several days, delayed response, please forgive me.
Air-bearing motor flywheel system weight 8.5kg, flywheel diameter is 140mm, the quality of 2.8kg.
Air-bearing motor flywheel system is designed for my reference Turntables, not sold separately, so sorry.
Thank you for your interest!
