ultimate mini mill power feed.

[MCRIPPPer]

this is a power feed i have been building. it uses a motor and gearbox from a dewalt drill. the gearbox has 3 speeds and metal gears. i had to make shifters to replace the shift drum that was on the drill. it has a clutch do engage and disengage the lead screw. i have a motor controller and switches for controlling the motor coming in the mail. just need to get the electronics sorted and maybe give it some paint to match the mill.

in the video it is running off of an atx power supply on the 5V rail. on 12v it goes pretty quick, but the power supply trips sometimes if i just connect the motor from a dead stop(atx power supplies have short circuit protection.) hopefully when i get my pwm controller i can use 12v. the power supply can handle something like 20A at 12v, and 30A at 5v. the motor is from an 18v drill.

here are some more pics with the covers off. you can see the clutch and shifters.

in the video the alligator clips short out and flip the power supply off.

Nice job, looks very professional, and a clever re-use of a drill.

Now I dont feel so bad about all the chips around my machines

lol yea. i clean up alot but the chips are always being created so its always dirty. i usually clean up between projects, but sometimes my tools get hidden under piles of swarf and i need to clean earlier.
