[Syrupmakers] Cane mill bearings

[DBACrownhoney at aol.com]

Ya, I tried preheating it. I used a big propane weed burner torch. It got  it 
pretty hot. I think if it brakes all it will do is allow the juice to get in  
the bearing box. If that happens I think I can JB WELD it enough  to keep the 
juice out. 
 As for the zinc. I haven't used it before, but there was a guy in N.  or S. 
Carolina making bearings for Chattanooga 12's and he's the one that told  me 
about it. He said his have lasted a few years so far. I also researched it  and 
found a lot, much more severe, applications that it's used in. 
I plan on putting the mill back together today, I'll post some more  pics.

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?
 
Here's the link to the  pictures:
