Guys, I have a manual spring bender that I made from a small 7/12 lathe spindle and chuck.
There are no motors on it and I would like some help designing some controls for simple motors. The springs I make are both left and right hand twist torsion springs with 4 coils made from .31 SS spring wire.
They turn out fine by hand, but tedious to make. I might use a couple hundred a month of each side. A motorized machine will most certainly be of value.
I can show a picture or two of the spindle and the fitting I made for the chuck.
I will need some help with the controls I think.
It needs to turn clockwise for one side spring and counterclockwise for the other. Each gets 4 turns. Not sure what kind of control and motor might be best for this.
Any thoughts or ideas?

Thanks in advance for any light you can shine.
