Homemade meat grinder

post #1 of 18
Thread Starter 

So waiting on parts to get here for my smoker mod and seen the other day someone posted on converting a hand crank meat grinder into electric. So I decided to share my version on this mod. I built this about two years ago and unfortunately didnt take any build pics. So I decided to somewhat tear it down for a few pics to show how I built it.

 

 

 

 

Shaft rpm is 155 rpm due to pulley ratio.

This is a vintage gear reducted drill motor. It's 3/4 hp and output at the shaft is 275 rpm.

 

 

 

 

This is normally how I end up cleaning it, at first I was pulling the 4 bolts that hold the grinder to the base but anymore I just pull the auger out and wipe down while still attached.

I like it... trying to figure out what the drive was from ? or did you make the whole enclosure ?

I made the enclosure, wish I had build pics, it's mostly separate panels welded together and blended together on the outside, the upper shaft is turned down to 1" and ran through a ball bear, 1" id and 2" od. Held in with a snap ring.

Good job!  But, without some kind of guard, you've got an invitation for disaster.  Even the most well-meaning of professional meatcutters have gotten their fingers chewed off in half a second with an open throat on a grinder.   Being so handy, I'm positive you could come up with a guard that would let meat through but not fingers.  Otherwise, it is an accident waiting to happen.  I've seen it happen myself, and there is nothing left to sew back on; revise the stumps and let it heal and hope it doesn't get infected.  Only thing worse is getting your fingers/hand caught in a cubing machine; they normally have to call for the jaws of life to get your hand out of that.

How about a high rise sleeve attachment raising the height of the throat another 6 inches; just a round metal sleeve with a cutout for the contour of the body?

Yes, safety is always on mind. I am a machinest and operate very large machines with fast movements, one wrong move and a person could get seriously hurt. That being said, I did start a pan that would attach to the grinder with slots to feed meat through. I just never finished it. My biggest concern is when people borrow the grinder. The last two deer seasons it bounced around from friend to friend. I would feel horrible if something happened to them so this season the guard will be finished.

I really like this idea, as my cheapo grinder just died, and need to do something for a grinder.  Was that a 1/2 inch or 3/4 inch drill?  What rpm is your auger turning?  Is the case stainless, steel, or aluminum?  Lots of questions, but what a great job you did on that case!  Just joined to ask you about this build.

I believe it was a 5/8's chuck. I bought 3 different sized pulleys for the motor shaft and played around till I settled on the 3 to 5 ratio. I believe I calculated it out to 155 rpm. The case is all steel, just painted with silver paint. It really does work good but as others have mentioned it does have safety issues in which I need to address.
