Tel has covered it, but it might be possible to cut a plug from an odd piece or corner of the marble and cement that into the unwanted holes. It wouldn't need to be the full thickness, so you might get more than one plug from the same drilling. However, cutting the plug is not going to be easy, so probably the epoxy method is best. alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. ----- Original Message ----- From: "Ronald" <Ron@xxxxxxxxxxxxxxxxxxxxxxxxxx> To: <modeleng@xxxxxxxxxxxxx> Sent: Friday, October 15, 2004 9:12 PM Subject: [modeleng] Re: Drilling quartz I want to mount a model on to a large piece of white/grey marble I need to know the method used to drill it and also what to use to fill some holes in the wrong position so that it will look unblemished line.
