My latest antique shop purchases just arrived a Ben Wade Martinque with an acrylic stem and the bowl of a Ben Wade Royal Grain with a vulcanite tenon broke off in it. The broken tenon was easily removed by hand using a drill bit just slightly bigger than the hole. Twisted the bit by hand until it grabbed the vulcanite and it pulled right out.
This is the Ben Wade Royal Grain bowl.
