A couple of things... The SDS will do nothing for you if your turntable speed is not stable. In other words, there are two flavors to the problem - stable speed but not at 33 1/3 and unstable speed. The SDS will only solve problem number one.
Second, as far as I know, the rim drive doesn't work with the Scout. You need a Scoutmaster, HR-X, or TNT-6 to use the rim drive.
I've found that speed instability is most likely caused on the Scout by a worn belt. Try replacing it. Other than that, make sure the table is level and the platter bearing is lubricated with white lithium grease.
Cheers.
