Completed a couple of parts. The plywood construction of the plinth means a separate heat sink is required for the regulator, I saw a piece of extruded heat sink on Fleabay, it had various protrusions but when all these were cut off it left a simple profile I could work with. The doughnut shape is for mounting the bearing, it fits on the underside of the plinth and spreads the load, preventing the screw heads from biting into the ply. These will get a coat of etch primer before fitting. The drg they are sat on is one of a series of Acetate overlays I use during construction. These help when marking out and when checking for correct positioning of inserts etc. against the PCB and original Technics Chassis.
