From Looking at the images of the 101, the bottom of the Platter Spindles Bearing Housing, projects into free space between PCB and the Vented Protection Cover.
A Part can be bought/produced (shaft collar or similar)that clamps onto the Bearing Housing and projects through a penetration made into the vented cover.
Additional Base Bracing, can then be designed to receive the projecting part, to incorporate a anchor point for the base of the Bearing Housing.
On the Base Bracing, another collar can be added that has the walls drilled to receive Grub Screws or Similar, these can then be used to apply force to the bearing base, and lock it rigidly, in interference fit is not desirable as the rigidly anchoring method.
Lenco Heaven has been showing TT designs doing this for numerous years, a method can be found that is to ones own liking.
I encouraged this on a TTS 8000 not too long ago and the owner was thoroughly impressed with the improvements detected, they has a Stock and Modified model to do comparisons on. The TTS was a much more difficult model to achieve this type of anchoring the bearing housing on.
