Another good Tool for VPI Table


Today I recieved my el cheapo Dial Indicator, and Vacuum Base-Stand from Harbor Freight for $37 shipped.

I knew my VPI HW-19 Mk-IV Platter's 3-point leveling adjustment was slightly off, and the Platter initially showed a .012" "Hump", or +-.006" error. After 15 minutes of adjusting, I got that error down to a .003" "hump", or +- .-0015" error.

For those who have such an adjustment on thier Platters, this might be a good tool to have in one's arsenal.

Jean, The Metal Tip on my Dial Indicator looks like a small Ball Bearing, but it doesn't roll. As a friend mentioned to me, it would as well be a simple matter of covering the tip with a small piece of Cellophane Tape to prevent any acratching of Platter Surface. This would probably insure better accuracy rather than a makeshift Platter Mat.

I would assume VPI would do this service if you sent Platter-Bearing, but the shipping cost alone would probably equate to the cost of the Tools, and then you have them for future use.

The Vacuum Base Stand that I ordered with the Indicator from Harbor Freight is a quite massive, and heavy piece, and very nicely built. The Dial Indicator is as well, a quality piece. I feel I got more than my money's worth with this tool.

I would assume everytime I remove Platter for Lubrication service of Bearing, that getting the Platter positioned exactly again on the Bearing Flange is virtually impossible. Mark

Holy moley Jean, what a system! Very unusual I must say, I never seen such a configuration on a Turntable.
Just awesome! Mark
Thank you Mark. This is a project started with the rediscovery of rim drive benefits over belt drive, but no upgrade from VPI for single motor, so I tried with spare parts and the result is well superior compared to one platter belt drive. The project is so rewarding that I continue with better damping and a new plinth will replace the acrylic one, a sandwich slate/aluminium/carbon full size plinth with a cool design. As always I have to try and compare before adopting a new step in progress. Also mylar belt drive with modified motor rubber shaft soon coming.
The tool you suggest on this thead is essential for proper platter adjustment.
Thanks for the input !
Jean.
