New Power Feed for Grizzly G0759

[Josh Bowman]

Just got done with my power feed for my G0759 mill. Basic inspiration comes from the Grizzly power feed. The box is 2 pieces of aluminum angle, drilled tapped and screwed together. The motor is a power seat motor and the shaft was milled to accept a 3/8th 14mm socket. The 14mm socket was friction fitted into some round aluminum bar, then the bar "grooved" and tapered to except an aluminum plate made into a fork. I peened the fork into a piece of steel bar scrap and tapped it for a 1/4" bolt for the handle shaft, then epoxied a ball on. The electronics are from Amazon as is the Switch. Overall......so far it works well. I did one similar on a HF mill, but had to engage the socket with my fingers. The motor speed controller will take the motor from a crawl to pretty fast.

That's pretty clever. I'm assuming the motor has enough torque not to stall out during a cut. Do you have any trouble engaging the nut?
The Bridgeport power feed quit working on my mill. The fuse is good, I need to do some trouble shooting with it.

As the folks said at American Science and Surplus "it will move your butt". It will stall, but takes a lot and giving that the mills table as some gear reduction, I can't hardly stop it with my hand. I use a lot of these motors and controllers for other projects and found if they do slow down, something is wrong. Just went out and squared some stock with a 3/4" bit at full speed and the bed did not slow a bit. The cut was not real heavy, but enough to make the mill shake a little. The nice thing about these motors is they are only about $15 at American Science and Surplus
