Just a note about the knives. If you are buying them from Sears, be
very careful. I had a major problem some months ago (google jo4hn and
jointer for documentation) where replacement knives differed in width
from one end to the other by .008". This was enough to allow the knives
to come out of cutter head and take a piece out of the infeed table.
Happily no harm was done to yr hmbl srvnt.
