VPI bearing and platter swap - inquiry


I think I might have messed up with my recently purchase of, what I mistakenly thought was an Aries 1, but, turns out it is an Aries Black Knight (Aries 2?) with the inverted bearing.

I had intended on swapping my platter that I have on my HW-19 MKIV (TNT MKIV platter, non-inverted bearing) but I now realize there is a bearing compatibility problem that I’m facing.

I don’t have the Aries in my hands yet so I’m just trying to get a head of these issues and I need guidance.

Question, if the Aries BK bearing plinth whole is 1.25" in diameter, will I be able to attach the smaller 1" diameter bearing to it?

I actually reached out to Steve Leung of VAS and had a nice conversation. Super nice guy and best part is, he has extensive experience working on VPI tables. I believe he was once employed there and worked directly with Harry.

Steve is closer and much more available than VPI so this is really good news.

You likely are going to have to drill 3 holes in the Aries plinth and add a bush to take up the gap ( VPI used to sell them ) but the bush is only for centering the bearing, it is not actually required. The Aries has a compression fitting - no screw holes required.

Also likely you will need a new pulley as the 2 platters are mated to different motors - 300/600rom.

In my experience inverted bearings do have some advantages if they are designed well.

Yep, I think drilling holes for the bearing is definitely in my future. 

I had another nice conversation with BRF about all this and he did say that the Aries 1 and 2 have a 1" hole rather than the larger 1.25". So, this might turn out in my favor. I should know what I'm working with once the TT is delivered in a few days.

Soooo, the Aries arrived....damaged of course.  SMH.

The 20lbs motor pod was not packed in a separate box and was thus left to bang around against the plinth. I’ll have to deal with the seller next week.
