I would say get a shaft that fits a stock chuck (drill press chuck for example)<div><br></div><div>Mount a pulley drive on it, and drive it from an RC Brushless DC Motor, with an RC Speed controller. You can send it simple servo signals (pwm) to control the speed accurately and easily, and the whole thing would be quite high torque, and fairly cheap. And no fancy electronics to power the motor, just feed it raw 12VDC from your main PSU.</div>

<div><div>Hi,<div><br></div><div><div>I want to make a couple small CNC mills for fun. I decided the Mantis is too small so I am doing other designs. I want to use it for cutting balsa wood and the other for more general purpose. </div>
<div><br></div><div>I am looking for ideas for the spindle for cutting balsa wood. I think if it had an 1/8th chuck so I could use my 1/64th end mill that would be cool. </div><div><br></div><div>Any ideas what to use for the spindle??</div>
