But even this is speculation. But doesnt the quote also include first hand observations about the exact same problem situation as we've been discussing ? That heavy hammers affected tough in a negative way, but tone in a positive way ? And I am curious... is a 22 pound sheet the same thing as saying 22 pound hammers... as in did the Japanese hammers you mention below use a 29 pound sheet ? Also... are you saying that a 22 pound sheet can result in a lighter hammer then a 18 pound sheet (assuming same core material) ? > > Del > -- Richard Brekne RPT, N.P.T.F.
