Building a Clay Mixing Pug Mill - Part 2

[@Scott_C]

I love this project, not anything I'll ever be able to build but I love living vicariously through you. The last pug mill I used had a formed pushing plate that made it so that any Clay sticking up out of the feeding hole, was pushed down into the blades. May be something to think about.

Wow! Thoroughly impressed!!

[@centralparkcoffeeco.cafeba6634]

Pretty darn amazing for an accountant !!!

[@hawkintelligence]

uh.. so how much? If you build it.. they will come. I'd be happy to pay less than 4k for something that's useful. :D

[@freddiemoretti8456]

Very neat! Enjoying the build. Would PVC hold up just as well as the plastic?

[@JustinsMakery]

I've had the same thoughts! I snagged a scrap piece of 8" PVC from a construction lot. Pretty heavy duty stuff. Not sure if it would flex over time, or erode with friction.

Hi Justin, Do you have some kind of trust bearing?

[@JustinsMakery]

Not really. The rearward thrust is passed into the gearbox, via direct contact with the auger. The locking collar clamped to the auger shaft keeps the auger from backing out, and transfers thrust to the side of the flange bearing. The flange bearing isn't really intended for this, so it is something I will need to keep an eye on.

This is legit. Very cool project. Can't wait to see how it performs.

[@bjornlindberg9779]

Cool project!

This pug mill channel reminds me a lot of Matt Cremona's log trailer channel. 😄

[@hugoamkreutz2081]

Such a great channel I just recently got in to pottery and and have refined my own clay I got at the cliffs where I live

[@ClownWhisper]

you dont need to weld those bushings into that flange brother youre making this more complicated than it needs to be

[@markrussell910]

Hello, did you have to use stainless steel for the mixing parts, or could you have used regular steel? Pretty cool.

[@oldnubbins8060]

Have you considered ditching the coupler, putting the gearbox/motor below the impeller housing (flipped 180°) and driving the shafts with a chain/sprocket? You could then use flange bearings to align the impeller without having to maintain alignment with the drive train. Would make it a bit taller but shorter footprint.

[@JustinsMakery]

I have. It's a good idea. Either a chain, or toothed belt drive. Another advantage would be an additional gear reduction opportunity. I kind of have it stuck in my head to keep the area below it (in a future rolling cart) open for the vacuum pump, but there is obviously room for both.

[@oldnubbins8060]

@@JustinsMakery Well, you certainly have a knack for thoughtful planning on-the-fly. I live near a pugmill manufacturer and am familiar with their work - your design can give them a run for their money. Nice work.

Looking great! That thing will be a tank and last forever. In my previous classroom, I had a Walker pugmill. I loved that thing, but cleaning it kut at the end of the year took a while...

Me - runs out and buys 150,000 worth of shop equipment to make a pug mill and save money - and yet with no skills have to buy one any how.
