My dad  and I also repaired a crack with JB weld, it was on the hopper of 
a  P&O badged Nelson.  The previous owner had soldered it closed, and  the 
first time we put water in the hopper, it all leaked out the crack we  
did not even know existed.  We had just pulled out the solder,  cleaned 
up the crack with some wire brushes and emery cloth, and finished  off 
cleaning up with some alchohol.  We didn't do any grinding, just  pushed 
the JB as far into the crack as we could.  This has held for a  couple of 
years now, with no problems. 


Thanks for the information.  I am leaning towards using JB  Weld.  However, I 
have a neighbor that works in a machine shop and he  suggested that I pin the 
crack.  Apparently, there is a process using  overlapping tapered pins along 
with a matching drill to seal cracks where it  isn't possible to weld the 
crack.  I have repaired cracks in automobile  heads using tapered overlapping cast 
iron threaded plugs.
