[QUOTE="Wally69, post: 310144, member: 1916"] Yes I do, for me it is a hobby, so I started with looking for a fully kitted out secondhand setup as the primary consideration and landed on an agatemasta (single speed) unit, then after receiving some training on a gemmasta (variable speed) found a second hand unit with a performer as an extra. Both have different mechanical controls to get the cut right. Recommend :rolleyes: - I like aspects of both machines - so I would recommend getting one of each :D although I exclusively use the gemmast now as it has the ability to tune out a spiral (slight misalignment in the squareness of the main shaft to the lap) and the variable speed control. I think the key to cutting a good stone is probably more about the understanding of how to adjust geometry and cutting/polishing techniques. Speed is enhanced by the acuracey and precision of the machine and the functional control of the adjusting devices. Lap speed control is a factor that affects polish speed, but I think it will take me a few more years to fully understand the relationship between stone types, polishing medium and lap speed. In regards to new machines, I like the concept of precision depth cutting on rigid cut angles with a precisely tuned machine as I envisage there could be a significant speed advantage. Good luck :cool: [/QUOTE]
