I don't like the jointer pal, because the knives always seem to move when
tightening the bolts. I never get the ±.001" they claim. Instead, I use a
dial indicator. By using the height adjustment set screws and holding down
on the knives with a wood block when tightening, I get great results with
all knives nearly dead on the mark on the dial indicator (± .0005 or less).
It takes longer, but then I don't change knives every day.
I just went through changing out knives on my 6" Jet jointer. What I found
was that it really helps to "...read, understand, and follow the directions
for your power tools..." as Norm says. Once I did that, the Jointer Pal

I don't know about +-.0001 tolerance, etc, as I don't have anything to

after using the Jointer Pal to put in new, sharp knives -
It would help to have a "flat" open-end wrench. I bought my Jointer used at
an auction, and I didn't get the flat wrench that Jet supplies. Instead I
was using an open-end from Craftsman metric set.
