Timeline Calculator

I just made a calculator in Excel for the Sutherland Timeline. You enter the distance to the wall and the laser deviation per revolution and it gives you the circumference of the virtual circle that the laser travels, the speed error of your platter in percent, the RPM your platter is off by, and the actual RPM of your platter. It can also tell you how many Hz a given frequency is off by.

Let me know if you would like to try it out!

I guess the site upgrades have temporarily disabled the ability to email other members. If you want the calculator, please do as Ecir38 did.

Ecir38,
I have never seen your system pics before. Is that a slate plinth you have your Garrard 301 mounted in? It looks great! I'm planning something similar for mine. The calculator is on its way.

Ketchup, it is one top layer of 1/2 mdf and two 3/4 birch. Sounds great, makes me wonder about the high mass plinth debate. Table was previously in slate but think this sounds better. Thanks for the spreedsheet although haven't seen it yet..

Hi Ketchup

Being able to put a percentage of accuracy to my tables will prove to be very interesting. Thanks for doing the work.
Would you be kind enough to send me one as well please to:
rugyboogie@yahoo.ca
Will post the results of my four tables.
Thank you very much,
