G'day .
Small disposable paper drink cups are about 3/4 filled with gumnuts and about 10ml of clear epoxy casting resin is poured over the nuts to glue them all together and stop them floating, then into the pressure pot .
Next day the cups are topped up with resin and again preasurised .Next day the plug is removed from the cup by cutting down the side with a knife and pealing off the cardboard .
After standing for at least a day for the resin to cure , the top surface is sanded flat on a linisher then the plug is held in a chuck and drilled and tapped to suit the bottle stopper mandrill, ie a suitable sized bolt with the head cut off .The stopper is shaped with a carbide tool and a negative scrapper .Flaws in the surface are repaired with 5 minute epoxy . The finish is two coats of polyurathane painted on .
Hope this is of interest .
