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?

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.

 

 

Wow. Sorry to hear it. That was not a very smart person who packed up the table.
