Thanks, I may resort to this. But I really would like to find out first, why in the world no one has ever mentioned not being able to fit standard (?) replacement buttons into the standard holes of a standard Comet clutch! As is, the oversized buttons would break at the shank, if I would try...

Comet Clutch Replacement Buttons Don't Fit Just ordered six new genuine Comet 20/30 series clutch buttons from BMI. Their cylindrical shaft is supposed to fit flush, with a bit of pressure and some hammering, into the clutch plate holes. But the shafts of the replacements are clearly thicker...
