It's a real cheap mini-mill, I got tired of drilling and hand filing. I spent more time working on the mill (getting it true) than on making parts. I have an RC-Monster motor mount that I could have used with a spacer to set the motor back, but it was an older model and wasn't machined for the brake parts. So I decided to make a simple mount from scratch. Eventually my setup will include a rear support for the motor so all the stress doesn't fall on just two endbell screws.
My Neu motor cost more than this mill.
