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.

Hi Mark, this is an interesting tool, I adjust my platter leveling rotation by eye but I am sure it is more accurate with a dial indicator. Is it the 30$ one on Amazon? It seems quite cheap for a precision tool !
So do you put one point on the platter turning and any off deviation is recorded by the magnetic base ?
On the VPI 3 points platter I find the easy way by unscrewing the 3 allen screws completely and platter turns flat (by eye ). Thanks for the info.
As you can see on my system pic I use the 3 point platter as rim drive platter, main platter is the newer superplatter and does not have that 3 point screws anymore. So I think that with inverted bearing it is not so important. Maybe you
could try unscrewing the 3 screws and have total platter/bearing contact and compare the sound by ear with screws tightened to see if there is a real benefit.
Dear Mark, you excited my curiosity and I ordered one . I will try to tweak it for better turntable platter use, as replacing the metal tip by some kind of roller.
But I will inform you. It is an useful device for any TT to check bearing wear. I keep you informed.

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 !
