I have removed the motor housing on my MK3 from the original square chassis
See the triangular shaped TT on my krebsupgrade.com web site.
The rather flimsy naked motor housing has been laminated ( epoxy glued and bolted) into a machined duralumin housing of 15mm wall thickness. This in turn is adhered to a 15mm thick lead disc. ( the piece that was cut out of the plinth to accommodate the motor)
In my original post on this thread, I talked about minimizing material changes and joins in the platter arm loop along with consideration of propagation speeds, absolute dimensional stability and stillness.
This leads to the conclusion that the chassis has to go.
I also replaced the platter with an acrylic duralumin lead composite.
Regards
