my mini mill power feed.

here is a power feed i have built from an old dewalt xrp drill. has 3 speeds on the tranny. will get some better pix of all the workings soon.

That is the cats meow. Can you get it to run really slow for a good surface finish or is it more a roughing speed? That is a pretty slick idea anyeay you slice it and I would love to see how you adapted everything together.

that's a great idea. how did you overcome the automatic "no-go" with out power ? do I see a jaw clutch arrangement somewhere in there ? you may have started something here

 

[MCRIPPPer]

it has a clutch to disengage the lead screw. the two sliding levers are for shifting gears, and the other operates the clutch. in the video you can see the lowest speed, but it will get slower once i get a motor speed controller.

here are some more pics with the covers off. you can see the plate/standoff construction.

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

That's a real work of art, man. Nice job. I have a Black & Decker drill that both the batteries have gone south on and I have no intention of buying new ones since I also own Ridgid drill with lifetime battery warranty. I may have just discovered a new purpose for it. )

thanks.

power feed is definitely worth the time to make. it does not have to be as elaborate as my power feed, in fact, here is my power feed V0.1, using the same motor and gearbox, but also using parts of the drill to mount it.

+1 for creativity!

Have you checked the drill motor for overheating?

 

[iron man]

There are a bunch of sites that this same drill motor has been used for power feeds the motor has more than enough power for the mini mill and I have never read one instant of the motor ever over heating or for that matter any trouble at all.. Ray

Great work. I was just thinking RBeckett was just asking about something similar too.
