I ended up going with the cylinders for the counterweights. Used 2 equally sized ones - 1 on each side of the 2. The best I could find was one that will give me about 12" of z when done. Not to bad. I've got them mostly installed but have to finish them up. I had them on, but took them back off to paint the munting brackets.
Now my next road block. I am getting quite close to finishing this mill, just working on some bellows for the ways, but now i need a motor for the spindle.
I have purchased an R8 minimill spindle to use and wanted to use one of the motors from Keling, but I have read several bad things about the lack of torque here on the forum http://www.cnczone.com/forums/produc...ldc_motor.html.
I had even gone as far as machining a mount for the 1100W one. Now, they appear to be "out of stock" at keling, they are refunding some peoples money due to poor quality (not the fault of Keling, they are just providing excellent service in a bad situation). So now what.
Anyone got any suggestions for a motor around 1 1/2 HP with a frame size similar to a nema 34 notor? Will a servo motor work?
I want variable speed, controlled by mach 3, ability to tap, and decent rpms (say up to 5-6k). I'd like to keep the price including everything to 5 or 6 hundred if possible. Suggestions?
