s.ara.h.s.agar.eno, I was not aware of recurring issues w/ Aries platter concerning warping, vibrations or other issues you mention. I've had 2 major issues with my Aries; 1) speed, 2) the worn bearing.
I had issues with both the SDS and ADS. Eventually after investigating other speed controllers, I worked with SOTA/Phoenix Engineering in their development of their Eclipse series. I sent them my motor pod and they used it in development of the motor to be used with the Condor PSU in combination with the Roadrunner. I already had the Roadrunner and replaced the VPI motor and ADS with the Eclipse motor and Condor PSU. For me, this system provides the startup and speed consistency I desired.
After Harry repaired my bearing, I took SgreenP's advice and cleaned the bushing and tower with Hoppe's 9. It made a huge difference and precluded the necessity of using any bearing lube. Previously, I only used the VPI lube but no longer use anything. I just clean with Hoppe's 9 and have no issues.
