Anyone come across these for the str machine? Full drive board yes? https://www.ebay.co.uk/itm/Padholde...with-Foam-of/263722278316?hash=item3d67129dac
Cheap if it is. Waiting on the seller to confirm. Could do with a couple of these for different segments.
Cut out a circle of ply and screw directly into the board, then just use Velcro pads or spray glue to connect sanding discs. Viola
