[Fot] Survey: TR3-4 camshaft breakage

[Bob Kramer]

Bob,

Larry Young, who is designing camshafts for some of the FOT, likes to use 
new blanks rather than regrind for his race camshafts. His thinking is that 
during the regrind they also reduce the diamter of the shaft to keep it 
smaller than the base of the lobes. He is worried about your exact problem. 
Maybe he'll chime in.
