Simply drill a 9.5mm hole in in the centre of one end of your chosen workpiece and screw the workpiece onto the mandrel, then take it off to put the plastic washer in place and then screw the blank back onto the mandrel. Bring the tailstock up to the wood to ensure stability when roughing out and until the turning is close to completion, then remove the tailstock sand and apply your chosen finish.
The blank will be tight up to the mandrel shoulder when the turning is complete, using the washer will help release the work easily.
