SDS question


Hello friends,
I was checking my turntable speed today using my KAB speed strobe and found that my table was running quite slow. I had the VPI SDS calibrated at 59.85hz and I thought I had the speed perfect. Today, I needed to adjust it to 60.03hz to get it dead accurate again.
What might cause such a big change to have to be made? I was wondering if it might be the weather (it has turned cold recently here in Chicago)?
Any thoughts would be appreciated.
Thanks.

..just for your information. When my Superscoutmaster needed oil it made a ch,ch,ch,sound. When I called Harry, he said it needed oil and is sending some to me
Hi Tom. When I spoke to Harry about the Che,Che sound (he actually heard it on the telephone), he said there is an adjustment if there is too much play in the shaft. This can be checked by pulling up on the pulley. There should be a little play, but not too much. The play on mine was about equal, so the next step Harry said would be to put oil on the shaft. He didnt mention what kind of oil, but he said he would send some to me. I havent received it yet..this was only a few days ago. If you call VPI, they could surely answer your questions. ..Just for your information, VPI is closed on Mondays and a couple of other days. I called Tuesday and was able to get through. Stan
Sameswei...by the "brass piece" ..do they mean the shaft of the pulley? and if so, how do you get oil on that shaft, it being under the wide pulley
