New Teres Direct Drive Motor Available as Option

Pauly,

The flywheel effect of the platter on that cutting lathe would be negligible compared to the 75kg/cm torque generated by the motor. From pictures on the net it's evident that a really decent cutting lathe like the Neumann has a much stronger drivetrain. A lathe strong enough to handle the fundamental drag on the cutting tool should be impervious to small modulations in drag. Still, somehow tools never quite seem to be as good as they should be. I have a metal lathe with a 10" chuck & a 2hp motor & I still manage to find jobs that are too big for it.

I did find a reference to pitch problems introduced by stylus drag on lathes used to cut 78rpm records in the 1920s.

Occasionally, some of us forget that johnnantais single-handedly invented the idler table. Fortunately, we can rest assured that he'll always be here to remind us of his place high on top of the Mt. Olympus of Turntables.

Chris and all, what is the size and composition of the Verus' O-ring?

I'm already looking forward to lively debates about sonic merit and wear from various O-ring materials (urethane, flourosilicone, polyacylate, etc.).

Anybody wanna buy my tape splicer?

Tim

Tim,

The o-ring Chris supplies is from McMaster Carr, part number 9557K228.

How about a group power buy?! ;-)

Well, this is not the end of belt driven turntables, but this is certainly the end of the dogma that belt drive is (far) superior to direct drive. I think the proponents of belt driven turntables will disagree with this: they will miss the sight of the big external motor with the rotating belt (wonderful nostalgia, heheh). The Goldmund Reference I tt was a direct drive design. The same with the Rockport Sirius (if I'm right).
