Turnable database with TimeLine

Halcro, My test record that I use for the iPhone app is also flawed. The record hole is off-center so I filed the hole open a bit and I must center it as best as I can on the platter. I get differing Wow&Flutter measurements (between 0.06% down to 002% filtered readings) depending on how well I center the record. My record also has a slight warp and at around 12 seconds into the track the frequency shifts due to this warp. So my overall measurements look better when I start the recording past that warp. I did screen saves on sevaral measurement trials using the iPhone app and finally saw this pattern of speed or frequency shift at the same point every time.

Halcro, that new Victor TT-101/3 arms video is quite impressive. My belt
drive could not do that. I do see the value of testing with and without the arm
being in the groove. Unfortunately, my Timeline is gone so I can't retest or
shoot the video.

Your latest video seems to have much less drift than the first one (with 3 arms
but no music) linked in the OP. I wonder why that is. The drift to the left in
the first one looks like half the length of the Timeline dash so I guessed it is
3/8". The latest video drifts much less, but from about 3:15 in the
video to the end, it is clear that the TimeLine dash is no longer centered on
the blue tack but drifts to the left until about 3/4 of it is to the left of center
and 1/4 is to the right of center.

This is very minimal drift over 5 minutes. Perhaps Tony could calculate the
error if you give him the distance from spindle to blue tack and the drift
distance which looks to be about 1/8" or so.

Syntax did post a video of the thread drive Micro. I'd like to see some of the
modern DD tables like the NVS and also the BD TechDas.

I verbally reported some results I got with my SP10 Mk3, using a Timeline borrowed from my neighbor up the street. (Yes, there are two audio nut jobs living on ONE short block in Bethesda, MD, USA. What are the odds of that?) He was using the Timeline to prove to himself and to me how very unstable was his very high end very expensive belt drive turntable, with a massive platter, I might add. The manufacturer told him there was a fault in his new motor controller to account for his disappointing observations. And now recently the new motor controller and a new kind of belt have been acquired. I don't know what these two upgrades (?) have done to improve his situation. The laser beam was riding around his room so fast I thought we were in a Disco night club.

I've mentioned this before; one problem with the Timeline is that it seems to have been designed for the narrowest of the 3 possible spindle diameters. I found it will not fit on the spindles of my Lenco or my Kenwood L07D (or perhaps it was the Denon DP80). Has anyone else had this issue? Following on the heels of Dertonearm's clever protractor, it would seem that Sutherland could solve this problem by incorporating interchangeable spindle holes, that could screw on to the bottom of the device. Thus, even more vinylphiles could be driven mad.

Ok.., what is the music this time?
Nice

I missed your report on the MK3 with the Timeline. Are you able to repeat them here?
Thanks

Nothing to say except it was bang on accurate, with the laser beam hitting a wall 8 feet away. I did not try a wide variety of music, and I did not persevere for very long once I felt the point was made. Perhaps in 10 minutes of observation there might have been some deviation; I can't say either way. I think I watched the blinking light for 2-3 minutes at most. Then I fell into a "deep sleep" and did whatever my wife told me to do for a week. Eventually, I snapped out of it.

If you're asking whether I can post a video, the answer is that I lacked such a capability at the time, not to mention that I had no such idea, either. I can probably re-borrow the Timeline if inquiring minds want to know.
