Bill,

Just for rcw archives and my confusion re HP and what it is, whether
from dray horses or thorobreds, would you explain the differences
between calculated HP, advertised- nameplate HP, brake HP and any other
HP. I think that motor speed is involved in the first two, regardless
of pulley ratios. At least some drills etc. when run at usable speeds
don't seem to provide the HP the makers advertised. Maybe there is
"useful HP" ?
