[QUOTE="Sodabowski, post: 120394, member: 2712"] I know what you're talking about GallicProspector, I also kept my first stone - it was hand cut, no handpiece, with a small diamond lap on a Dremel tool... it's an emerald-cut green afghan tourmaline (might post a shot of it). Not done with the polish yet since it's the one that got me started on designing and building my own faceting machine (being a physics grad student and an engineer, I can handle that). Keeping track of your progress is a really good idea if you feel theneed for it. I would tend to do like Barney and don't call it the day until it's perfect, but that wouldn't give a clue as to how the journey began. It all depends on the stone's value of course, with quartz, even a very nice piece like your first one, no-brainer. If it had been something more expensive, well... I read somewhere else about an old machine being rebuilt with new brass bearings (the weakness of all faceting machines that have sleeve bearings) and that worked great afterwards, sounds you've got a recipe for success with that oldtimey piece of equipment, these beasts were made to last for centuries with minimal servicing. My guess is that the dust from all the cutting eventually makes it into the grease and/or causes abrasion in the brass bearings. Would you show us a picture of that machine by the way? I love old hardware! :D [/QUOTE]
