Turntable speed accuracy

Syntax: "Tweaking a dead cow to a horse is interesting, no doubt, but other Designers made better work."

That reminds me of an old Chinese saying, "ride a cow before you find a horse." For some people their turntable of choice is the cow... for the time being. :-) Or they think they're riding a horse? Or they are just "cowhide lanterns." :-D

Lewm ~ you don't happen to own a TTWeights table? I've now checked 2 TTWeights tables and both show inaccuracies via the Timeline, would like to have confirmed a third and then can surely say its a design fault!
Looking forward to your findings.

I'll ask this question again since the other post was deleted. What does everyone expect from their turntables when using the Timline device? Absolute zero drift of the laser mark? Here is another way to look at it. Leave the Timeline device on for 30 minutes. If you are comfortable cueing up the same record side twice, do that. So in 30 minutes the platter will rotate 1000 times. Since most tt's are spec'd to have a speed accuracy of around 0.02%, then you can expect to see the laser drift about 72 degrees in 30 minutes. That is 0.2 rotations out of 1000. Is that good or bad? That would seem very good to me. btw- the Timeline maker advertises an accuracy of 2ppm. I take that to mean the Timeline device is about 2 orders of magnitude better than a typical tt.

I hear you Tony but it seems nobody else is or wants to pay attention to you. They are believing that if the timeline isn't right nor is the turntble but yet there have only been just a couple of tables mentioned that the timeline is true on.

Tony ~ I'd be happy with what you propose BUT what I see currently with the TTWeights table is that the line moves EVERY rotation which to me is just unacceptable.
