[SEL] Cast iron repair

[Andy Glines]

The repair I'm doing is actually for my steam engine but it seems like an 
appropriate subject for the engine list.  I have a couple of broken or 
cracked castings to be repaired.  I can braze to do the repair but the 
repaired area sticks out like a sore thumb next to the original surface 
which is quite rough and pitted.  For the repair I ground a V where the 
crack was and also the surrounding area to shiny metal,  After brazing I 
ground the brass flush with the base metal.  Using a ball peen hammer, 
punches, & my needle scaler I attempted to recreate the pits in the cast 
iron.  Things went pretty well.  I may need to beat on it a little more to 
camoflage the repair.  Has anyone else doen this?  How did you do it?
