I put this on a Sharp mill. It took about an hour to install. Making sure to clean everything that came off the mill and grease it all well. I followed the instructions on shimming the motor and it has been working well for the last few months now.The brass gear collar needs to be trimmed down about 0.25-0.375" in length to fit the Sharp mill. With the length it comes you get maybe half a nuts worth of engagement on the handle retaining nut. Can either turn it down on a lath or cut it down on the mill you're putting this on.I have also noticed at lower speeds, sometimes the motor doesn't want to engage when switching to power feed. You have to give the speed dial a small jerk and that will get the motor going. But once it is going it has had no problems feeding at whatever speeds I set it to. For the price I paid, even with the quirks, I don't know why I didn't buy one sooner.EDIT:I went back and looked at the brass piece. If you were to trim it down the ball end of the handle would interfere with the motor housing. So the handle itself would also need to be trimmed on one side as well. I have been running it as is for a while and it has been fine. Eventually I'll get to trimming it down.
