I've taken half of this advice :)

The donut is in 3 sections to reduce material waste (I was able to use
offcuts) and just a single one which I can put slipper blocks each side
of. The drum now looks like this...

So I'm now after a couple of PTFE (or maybe even Nylon?) blocks to put
each side of it.

Only need to be about 20x30mm and as thick as required to hide a couple of
countersunk screws!
