I would head straight for the Proops stand and see what they have in the el cheapo range of diamond drills etc. Even if it doesn't work, it wont have cost much. The only other suggestion is to use a small piece of copper (or similar soft metal), coat the end in the grit of something harder that the quartz.. alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. ----- Original Message ----- From: "Tim Rickard" <the_viffer@xxxxxxxxxxx> To: <modeleng@xxxxxxxxxxxxx> Sent: Friday, October 15, 2004 1:25 PM Subject: [modeleng] Drilling quartz Sorry if this one is off topic too much. If it is tell me to get lost. Has any one any experience in putitng small holes through quartz? I've a daughter rather hoping I can drill through a piece of ametrine nearly 1cm thick so she can have a pendant. I'm thinking in terms of emigrating but if that doesn't work then diamond drills to be bought at Donington and lots of spit as lubricant but thoughts welcome. MODEL ENGINEERING DISCUSSION LIST.
