[SEL] Cracked Head/Vee grinding

[Ray And Erica Freeman]

We used to grind the prep and finish it off with a file. It lets the bronze
penetrate in a bit.

I'm no expert but have always been told NOT to use a grinder (of  
the abrasive type) to vee out a groove for cast iron welding as the  
abrasive (carborundum??) particles left behind in the metal may cause  
problems with the weld. I've always been told to only use a  file!


Jerry,
 
You are correct in not using abrasive type grinding tips to clean up  metal 
for epoxy repairs.  What I have are a couple of air die grinders  and use
high 
speed/carbide cutting tips to do the work.
