Hello, I have a Tre spade 22 grinder and am having a hard time finding a pulley wheel to replace the crank handle. I know they are easily available for the Porkert brand but these won't fit. Any help greatly appreciated.
 
Good idea the drive hub is a tapered cone with a flat ground on it. Centering it could be a bit of a bear, but do-able, thanx.
 
guido could you tell me what kind of gear box and coupling you used, I was thinking of driving it from my Beaver table saw, double speed reduction and the blade height adjuster will serve as the secondary belt tensioner. Direct drive however would be much easier on the bushings.
 
What ever you do don't weld the pulley on or you won't be able to get the auger out to clean it?Do as guido sayes and have the end machined with a keyway then you can take the pulley of with a set screw.Had my #32 done like this 20 years ago and never had a problem.all my friends use it its ground a pile of meat.
 
The old ChopRite #22 has a 13" pulley available only thru special order. They recommend a 1700 rpm 1/3 hp motor with a gear reduction to get the auger speed down to 75rpm for grinding. Do a seach on google for home sausage making and you should find the article with all the dimensions, pulleys, belt sizes, etc. Can't remember the link right now...KF
 
That's a great link BC Bigbore, unfortunately the hub for chop rite is different than tre spade but exactly what we're looking for. Looks like I'll be following Bone-collector's method.
 
savagefan, if you decide to go the machinist route, look for a small 50-1 gear reducer and hook up everything in line. That assembly from sausagemakers will turn your hand into burger as well. Worse yet, maybe your wifes or kids. That assembly, though effective, is unsafe. If you build gaurds around the pulleys and belts, it all becomes impossible to access, not to mention a major chore to take apart and wash. Princess Auto has small gear reducers for sale quite often or they can be pickd up quite cheaply at equipment houses like Aklands etc. :twisted: :shock: :D

This stub shaft can also be used to attach any thing else you want to. :idea: :twisted: :shock: :D
 
Taper a 45 gallon drum down the the size of the grinder and get a machinist to weld a 24" pully on it then jack up the rear end of the truck and slip the tire off the rim. Run a belt from the pully to the rim and fire up the truck with the transmission in fourth gear.
Works great as a sausage stuffer also but one can fill a room with sausage in a very short time. :lol: :lol:
 
Now that would cover the block-party sausage event, Walksalot :lol: :lol: Hey bearhunter, if you think the pulley arrangement is too scary, you ought to see the one my brother-in-law built :shock: Brings a new meaning to "Medeivel Torture Chamber" :lol: :lol: And his family has used it for many years with no problems so a couple small pulleys/belts ain't no big deal...KF
