Testament to how popular this style of machine is by the nations that manufacture modern iterations: Israel, India, China and now France thanks to Antoine. Probably one or two I missed in there. It's easy to see why production cutters love them, you can have a whole rack of dops ready and waiting with next to no adjustment between stones. Definitely a skill worth building for a well-rounded faceter.
What kind of disc are you using? Where to buy? U know one disc thin like paper for polish? I had one im looking since one year where they sale this u know?
Hey Justin. Have a question. Just getting into cutting stones. My question would be. What would good laps for Sapphire? It's all I intend on cutting. At least for now. Awesome show Good knowledge.
For cutting, any type will work fine; topper, plated, or sintered. 360/600/1200 is a normal cutting sequence for all stones on topper/plated laps. For polishing sapphire many people choose BATT, and you can’t go wrong with that lap as it’s pretty much universal. Some people like copper or the harder BA5T but if you’re just starting out a Batt is probably the best idea for all around polishing of sapphire and more. 8k/60k is a normal polishing sequence for sapphire.
Good morning , pls help me. I don't understand how it work he is used 1200 grid next Polish +14.000 diamond powder?? Because I used 400 grid600 ,1200,3000(grid lap from china. Next polycrystaline pandenium (3u) next polycrystaline pandenium 60.000(.375u)and nothing.... 😢Cooper disk have and Bart lab (stone amethyst) Charge disk: I do this, I make scratches on the disk, I take the pasta60.000+WD40, and press the bearing paste into the disk +-1 min and don't polish on my gem what could be the problem sir? Sorry for my bad English
@@makumegane9628 yes that’s the problem. You can’t polish any kind of courts with diamond powder. As you’re learning, use other stones like garnet, aquamarine, tourmaline, spinel, anything but quartz. Come back to quartz later once you’ve mastered some other skills.
I found this machine incredibly interesting compared to mast and handpiece machines I've been looking at. The part that shocked me was the price of a new one. I assumed it would be significantly cheaper due to it's basic design, i was very wrong! There's a fraction of the design considerations and components that go into building this. Many parts of the machine look almost cobbled together. It would cost me almost $6000 canadian, before tax and import, duty if not available here. I'm not seeing the type of precision components to justify even half this price. I had to comment simply because of how shocked I am. This machine needs a modern engineer and serious updating (including their recent machine). I build custom machinery for a living and I could definitely produce better in my home shop. I could do miracles in a properly setup one in comparison. I like the machine but the price makes it a joke.
getting the peg into the right hole all the time doesn't seem efficient, Antoine is having to lean over and look up to verify he's getting it in the right one, someone give him some Ibuprofen 😞 !!!

What stone is it? If it’s a quartz, switch to something else for learning. Your sequence is good.
@@JustinKPrim ok, thx. My stone is amethyst
