Hey guys,
I am trying to wrap-up my retofit project, and want to control my Boss 6 using a VFD. I noticed that the stock spindle motor only has a speed rating of 1415 RPM. I want to have the ability to turn the spindle to 5K. In high-gear, the spindle gear ratio is 1:1; which means I need at least 3.5:1 sprockets up top. I am curious as to how much you can over-speed one of these spindle motors without hurting it. Over-speeding it would allow me to drop the sprocket ratio a little bit, and maybe give me a little more torque at the cutter in high-gear. If I could drop down to 3:1 sprockets, it would also provide a better selection of sprockets to choose from. Has anybody gone this route yet?
Thanks,
Wayne
