[Syrupmakers] Cane mill bearings

[Richard Harrison]

J T,
     The photos look nice to me. As for welding cast iron, I hear that it needs to be preheated to work best. Nice looking bearings! have you used zinc/aluminum alloy before for bearing use ? Will it stand pressure ?

      Hey ya'll sorry it took so long but here are some pics of the zinc/aluminum bearings I've been talking about. These are for a Chattanooga 13. The 2 piece bearing was cast in sand. The other one I poured directly into  the cup and used a piece of spray paint can to form the socket for the shaft to fit into. I also left about 1/4" of the bearing material on the bottom of the cups so the shaft wasn't rubbing right on the cast iron. I don't  think I'll ever have to replace them. 
  Now I have a question. I think in the past someone took this mill apart and when they  took the top off they let the large roller fall over and cracked the rim around the hole. I welded on the cracks  directly behind the shaft were the most pressure will be. I know it's a poor excuse for a welding job but welding the cast iron is a lot different than steel. It's hard to hold an arc. Anyway, just wondering what ya'll think  about it. The cracks don't go into the main plate just that rim. Think it'll hold up?
