Direct drive vs belt vs rim vs idler arm

Hello Dover i just want to clarify that the turntable is not hunting correcting etc.. the reason you see the 33rpm marker moving is because i am putting lateral force(on the side of the platter) it is dead rock solid :)

Hi Richardkrebs/Peterayer, for the record that is Lawrence's video (Lharasim). Not mine. All I did was put it into a direct link on the thread for viewing.

As in my earlier post on 12-30-12 belt creep is inversely proportional to the elastic modulus of the belt.

Creep = T/r x A/E where E = elastic modulus .... Mark Kelly

if a belt is inelastic, then E = infinity, and the creep is infinitesimally small.

Halcro, thanks for making and posting your video. I just viewed it and have a question I don't believe anyone else ask as yet.

I'm not familiar with the Timeline, never having seen one in person. In your video there appears to be an initial flash on the wall above your FR arm, prior to your BluTak marker. Is that a reflection? I understood only a single flash was produced per revolution.

Thanks.

Pryso,
Originally Ron Sutherland made the Timeline with a 'chip' programmed to flash once per revolution.
Early on.......to make for easier adjustment of the 'flash' on an adjacent wall....he changed the chip to flash 5 or 8 times per revolution.
He offerred to change my 'chip' free of charge if I had the old one but fortunately....I had the new :-)
Regards
