Porkert #22 meat grinder MOTORIZED!

Here is a #22 Porkert meat grinder with the addition of a 3/4 hp 3 phase motor being tested. Future videos will show the machine work required to make this operate and the completion of the base and stand.
RPM is 153 and is driven by a 5:1 Boston gear reducer. First reduction is about 2:1, total is 10:1 from the 1740 rpm 240 volt motor. I reduced the diameter of the shaft on the auger to.750 inches and removed the taper. The bearing surface in the grinder body is a pressed in nylon or HDPE bushing. I also reduced the length of the auger by about .130" so that I could add a needle thrust bearing and thrust washer, rather than put pressure against the nylon bearing. I drilled a .3125" hole through the bushing and shaft for a removable pin. The machining was done on a Atlas lathe and the plate pin on the auger was chucked in a 3 jaw, and the handle bolt took a ball center. Runout was nil. A Lovejoy type coupler would be best, but I had these components in stock. The gear reducer has nuts under and over the base mounting points, so that it can be adjusted for alignment to the auger shaft. The unit will take meat as fast as it can be fed, and a hopper or feed dish will be mounted.

This is the most compact/ergonomic DIY meat grinder solution. I wish to have the time and resources to make one like yours.

Very nice smooth running machine, tnx for sharing my friend. 👍

[@stanzuray]

Like the grinder nice and compact.

Thanks, It does work quite well and quietly. Wish we had moose here, would love to process and eat. Lucky guy.

So nice and quiet compared to the electric grinders I’ve used. Thanks for sharing! Do you know the model number of the Boston gearbox?

[@RRaucina]

Thanks! You might find one on e-bay, it is new old stock, pretty old, like the 70's. Maybe $60. I bought another unit, a European motor/reducer unit for $40, but much larger and heavier. Graingers have some in that style but quite expensive. I searched the web, didn't see any quite like this one.

@@RRaucina yeah gear boxes can get pretty pricey. Automation direct has some decent prices on gear boxes but if I can i go with NOS from ebay.

[@USA__2023]

Since you're using 3 phase you can add a cheap VFD to it too. LOL

[@mikegajewski3713]

Delusions of Grind-ure. I think your grinder thinks that it is something that it is not.

[@RRaucina]

With a name like Porkert, it must have a big attitude.

Way too fast

[@RRaucina]

That's just 150 rpm, and its fairly easy to turn one by hand at 40 or 50 rpm. there is no heating of the meat, grinder stays cool. Many commercial grinders turn at 200 to 250 rpm.
