Kookie, I'll try to post up the pics of the one I did. I'm better at sausage and smoking meat than I am at computers and digital cameras. Like you I didn't like the idea of exposed pulleys and the large size required to achieve the proper reduction. The base is laminated particleboard, like a counter top. The motor is a gear reduction motor. It is only 1/4 hp, a little light, but it was free. It is 1725 rpm with a 14.4:1 reduction. I've never done the math, but the speed is just about perfect. The connector is a Lovejoy spider coupler. I had to have a machine shop turn the screw end to a consistent diameter since it was tapered to accept the hand crank, It already had a flat on it to accept a key. I also wired in the 3 way switch; for., rev., off, as well as a foot switch which is real handy. Northern tools used to carry speed reducing gear boxes, which was what I planned til this motor fell into my lap. I can't find them there any more on the net. I'll keep looking. You might try a local hydraulic shop, or material handling (like grain) supply place for gear reducers. I'm sure you've got something like that over there. Let me know if I can help with anything.

One more thing, the router speed control most likely wouldn't work for you. It is designed for a different type of motor. I believe a router or power tool motor is known as a "universal" motor. Turns at much higher speed. The type we are using for grinders is not designed to run at altered voltage. The router control is just a rheostat as far as I know.
 
now i am not sure what the speeds were...........but several of my buds built hog roasters...........used a motor for a furnace.......low rpm.......used for putting coal into the fire box...........anyone here remember that......??????????


fire box motor if i believe............i sholuld make some calls.......but most of them fellars have passed
 
Mulepackin, that is a sweet setup. I would like to run across a motor like that. At the ratio that you gave and your rpms your at about 119 -120 rpms at the grinder. I have a couple motors but one is a 3450 rpm so thats to fast would have been nice because it is a 3/4 hp and the other one I am not sure its out in my shed and I have to get it out and check rpm and size. The motor I figure thats easier to find then the gear reduction unit. After I did some research on the speed box, I can to the same conclusion to it won't work. But it would have been nice. lol. I am going to have to see maybe I can run across a motor like yours. Thanks for the help.

For what it's worth, my motor came from the radiology dept. of a local hospital. It was on some type of door opener for a small roll-up type door in the dark room area. Kind of like a small garage door from what I was told. Good luck in your search.
 
Kookie, I don't know where you are with this project, but I came across this in my Cabelas catalog. It sure should work with any electric motor, I would think.

Hey mulepackin....I have seen those in the catalog also.... Project is pretty much at a stand still right now.....To damn cold out to work in garage....I might have found a gear box, my uncle might have one or two, but I will have to wait till this summer when he comes up this way again.... Unless I can run across something local before then.........But thanks for the idea..........
 
Well I got a gear box for my grinder setup.....Just working on getting it all mounted.....I am mounting it on some 1/2 inch plexglass I have from a hockey arena.......As soon as I get it up and going I will post some pics here for you all to see...........
 
Well I got it all mount and up and running. I haven't had a chance to give it a test run with meat yet..... I think I need to get a new knive and some plates for it and a thrust washer or bearing washer for it, just to be on the safe side............But here is a pic of it was going to post more pics but the digy camera batteries went dead after one pic....

Kookie
I am very interested in viewing your accomplishment, but I can not see your posted pic.....

Also, may I ask if you ran it and were able to count the rpm's?

Lets see if it works this time. Not sure what happened before...I have test run it but not with any meat yet. It seems to work good. Not sure on the final RPM's. Don't really have the tools to measure them. Hope this works this time.

Hey Mossy, I counted the revs lastnight and I came up with 25 turns of the motor to 1 turn of the grinder, so 25 to 1 or pretty close to that. That should be pretty good for my 22 grinder. I had talked to a guy here in Bismarck that builds them and he told me I needed a gear reduction unit with about a 20 to 1 reduction. Hope that helps.
