[QUOTE="Lefty, post: 438284, member: 2976"] Bloke on another forum had made himself an amazing set up with about 16 wheels! He was a machinist I think so he must have been able to work out what could be done without overloading bearings, motors etc. That many wheels is probably a bit of overkill but he was having fun at least. Yeah, 6 wheels is a pretty ideal number in my experience, plus a threaded end so you can screw interchangable flat discs and polishing pads in and out. I can't remember what the diameter of the spindle on mine is. If you can build it to take commercial diamond cabbing wheels that's ideal. The old one we inherited came with silicon carbide wheels. The old lady who owned it cabbed almost exclusively opal on it so that was probably fine but if you cab harder stones the silicon carbide wheels probably wear down pretty quick (though they are fairly inexpensive I think). Diamond wheels are more expensive but the better ones tend to last a while and diamond will eat through any stone without trouble. [/QUOTE]
