Hobart Meat Grinder Rebuild

[nickelmore]

Not sure if this is appropriate or not to post but this is one of my hobbies.

I have been working on my new years resolution to finish some of my lingering project BEFORE i start new ones......

Scored this on CL in 2013. It ended up being a little bigger and heavier than the picture....

I have a bad habit of not being able to leave this as they are....so it got put on the refurb/project list at the shop.

Like most of my projects the research takes longer than anything. The interesting thing I found is that the front cover that holds the grease was sealed with plastic filler (bondo). The imperfections in the super thick cast steel were also filled in.

Some things I changed:

Rewired from 220 to 110
Changed front Oil Seal
Changed Grease
Cleaned/polished armature and brushes
New power cord (Long)
Por 15 base coat
Rustoleum "Hammer Finish" top coat
Stainless screws for front cover.
Replaced power switch
Moved power switch to back for safety
All the plastic filler was removed

Lots of beer was consumed while removing the old grease. The inside of the cavity had a primer coating so I was unable to use normal solvent. Final cleanup I used another 12 pack of beer and some water based de-greaser.

Inside the front hub after cleaned up. Tried to get the seal out in one piece to see if there was any numbers on it.....that idea did not work so well. Of course there were no numbers on it.

Left over por 15 from other shop jobs for a durable base coat

Motor specs..glad I found this. It was wired with a 220 plug when I bought it. It decodes to 110 or 220 v 1 means single phase (which i knew). I was thinking i had to put a 220 outlet in my prep area. The only problem was that there is no wiring diagram and only a couple of wire tags.

I have a #12 hub that I usually use, but I wanted a #22 hub similar to the one I used as I was a teenager. I am most curious about the rpm of this unit. I think my #12 turns too fast.
I also have manged to collect a couple of heads.

I use a foot switch for safety when I grind so I will see which one of these works better.

I have a stainless cart that is a little lower that it will sit on so I can wheel it out of the way. Originality I wanted to but it in my mobile processing (project #12)trailer, but this thing is WAY to heavy to be portable.

I saved some venison scraps for test runs

I also picked up another one like this but it is 3 phase. Have not even looked at that to see if I can swap phases, probably not so I will just refurbish it and trade it off.

Very nice work. Did you find a modern replacement for that seal?

That's a nice restore on a cool piece of machinery. I have friends who make a lot of venison sausage every year...someone doing that would really benefit from an item like this.

Out of curiosity, why did you not coat the inside of the feed area? Won't that be prone to rust and contaminate your meats? Have you considered an enamel coating for it? Or would the temperature have to be too high for the aluminum?

Yes, I measured it up and found a Chicago Rawhide number and found one at the local Napa parts store.

The feeders are cast steel and coated tin. I just had some extra por 15, If that one works out I will send it out to get re-tinned.
