It is always by a set of tools, no matter foot powered, steam powered or electrical, that transfers the force through levers or transmission mechanisms to create spinning, for wheel, drill or grinder. “Spinning” here is the true key word, I think.</p><p><br /></p><p>[ATTACH=full]549902[/ATTACH]</p><p>For understanding of machinery tools lead to uniformity and repeatability, with no offense, I see that you probably haven’t experienced hand working with similar tools before. I can try to explain with my own experience. Though I haven’t work on gem engraving yet, I have worked porcelain art by wheel throwing, and familiar enough with both traditional foot powered wheels and modern machine powered wheels. The working experience is absolutely different. With traditional tools, it is not about eyes&amp;hands, but more like an exercises that requires coordination of the full body and an art of balance of muscles and brains. Moreover, with foot powers, you will never get the tools spinning in the exact same way as the last power push, therefore each carve is always slightly different than the other, creating a subtle but crucial irregularity. Yet with the machine powered tools, all you have to focus is your eyes and hands. And you don’t have to worry about pushing or the force because the tool is always going to spinning in the same way you set it. This constant motion in spinning creates subtle uniformity, all you need is steady hands, which is way easier.[/QUOTE]</p><p><br /></p>
