[QUOTE="Lefty, post: 152201, member: 2976"] A full set of Anthony's laps is on my list - I'm especially interested in his sapphire system - just looking for something I can use for little cost almost straight away. I've been told that quartz sometimes doesn't like to be polished with diamond, the laps I'm referring to are indeed the ones you mention Dug. I have had little success using cerium as a cabbing polish but the stuff on these plastic polishing films has done a very good job, perhaps it's a better grade of cerium? Perhaps having the polishing compound fixed into a surface rather than as a slurry helps avoid the "aggregation and flow" problem? In any case, it's done a good job polishing quartz. I have been told not to use them on garnet though. I originally envisaged myself cutting mostly sapphire and zircon but now I can see myself cutting a fair bit of quartz, garnet and topaz as well. Plus anything else of course but I can get my hands on those things easy enough. Ultimately I will need a variety of laps. Dug out all the old laps of grandad's, they look mostly in good condition and a couple of the copper ones are actually made by VJ from when they were based in Rockhampton, they don't appear to have ever been used.
