A few days ago, Leo Lopez had a snipe problem with his jointer table
when he used the powerfeed on it. Leo and I exchanged a couple of messages
on this and we think the problem was caused by the feeder pushing the
leading edge of the table down.
This week I had a slight taper problem. What I found when I put the
straight edge on the table was that the outfeed table was a few thousands
lower in the front. The solution I found was in not trying to readjust the
table but to check the torque applied on the locking cam. Like anything with
a lot of use the cam can wear and applying too much locking torque will
cause the leading edge of the table to deflect downward. It's not much, just
a few thousands, but enough to affect the quality of the cut. I cleaned off
the cam, lower the table again and just tightened slightly. Result was the
table was level to within .0015" over the length of the cutterhead. Once the
table was level I just reset the height for optimum cutting. Cuts like it
did when John H first set it up two years ago. A couple of people had some
trouble with the table adjustment and I was wondering if it was because of
different tightening torque's being applied.
Apparently the locking design has been changed on the new series
machines. It is like the Hammer series now, so this phenomenon should only
appear on the 7 series jointer/planer combinations.
If any one has any other opinions on this, just post them here.
