<VV> Removal of Casting Flash

[N. Joseph Potts]

John -
     Could you tell us the exact dimensions of the working end of the tool
you made? No doubt you had to cut and try for a while to come up with it,
and now that you have, it'd save the rest of us a lot of trouble if you
measured it and told us!

It'll be VERY slow. The trick I came up with is an air chisel. I made a
blade out of tool steel, with a VERY square and sharp end, just wide enough
to
fit down between the fins. I brazed it to an air chisel bit, machined to
take
it. Worked like a champ, and fairly fast. Required periodic facing to keep
the
square end with the sharp corners, but I totally deflashed a pair of 140
heads in less than an hour. Oh, and wear hearing protection. The air chisel
is
loud enough, but the ringing of the fins was worse!
