<VV> Removal of Casting Flash

[Mike Kost]

I've heard lots of suggestions over the years about how to remove the 
flash in the heads. One idea I've wondered about but never heard is sand 
blasting (after the passage is partially opened). Would this work? I 
haven't tried it yet. It seems like this would clean and smooth with 
much less risk than saws and drills.
