@dogberry I was recently advised against my intention to have the SP10 MkII stator Bowl inner form CNC cut into a Permali Board I own, as I was informed the use of wood in place of metal may leave me with shielding issues for the Magnetic Field. I haven't given up on the idea yet as I feel confident there is a spray coating that will discovered that offers the shielding properties that are suggested as being needed.
This will also mean the Bearing Housing will also have a Permali Wall.
The Wall might need to be Sleeve Lined with a Metal of Thermoplastic Sleeve.
If Thermoplastic is the selected material, it might be machined with an ID that is the perfect fit for the Platter Spindle following a Reamer Fitting.
For myself, this pondering is a Xmas Pressie for the mind.
