I've got an INCRA fence on my Delta miter box..used it for many years,
zero it on the measuring side of the blade, adjust the rule, set it
for the length of cut, and the length is spot on..but today I'm using
it, same blade, same saw, same everything..it seems cutting short the
kerf of the blade..
can't figure it out since I zero it on the INCRA stop on the measuring
side of the blade, and kerf has nothing to do with the measuring

Any ideas?
