In lbcd #1010, "Rob Reilly" writes"...in
fourths of an inch is the SU model number."
I have always thought that SU's were measured
in eighths of an inch. Using his example of
an H6, the throat would actually be an inch
and 3/4, that is, six eighths. True, six fourths
would be an inch and a half, an H6 is really
an inch and three-fourths.
