<DIV><FONT face=Arial size=2>Hey Terry,</FONT></DIV>
<DIV><FONT face=Arial size=2>I know I'm not telling you anything you don't
know, but here goes. The blade is diving some how, a flexible base might cause
that. If the sole of the plane is not flat, especially if it's high in the
middle, it's going to chatter. So, when you introduce a curve in the sole of
the plane, I know it's an outside radius, if your blade isn't perfectly
supported by the sole of the plane it's going to try to dive away from the
plane and into some nice virgin wood. Also, as you're working the wood into a
radius, if the radius becomes tighter than the sole of the plane, it can
happen, things are not going to work right and you'll get chatter. Bla, Bla,
Bla. I'm just thinking out loud. And you already said your sharp, anything
less than that and you get chatter. And I'm giving you a lot of chatter, but
then again, I'm a pretty fart smeller. Shoot some slip spay on the sole and
try to slow down your strokes and skew it a little. I ain't no expert
with hand planes, I've just done my share of screwing up with
them.</FONT></DIV>

<DIV><FONT face=Arial>Question for the wood chomping gurus out
there.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I have a hand plane that has a propensity to "chatter"
in use. Picture of it is below. The reason the base looks as if it is curved
is because it is curved. That's the whole deal with this plane - the base
curvature is adjustable to any gentle curve - convex or concave. It's great
for planing many wooden things found in piano bellies and jigs to
make those things. But it can be a bear when the darn plane wants
to chatter.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Obviously, the plane is not a 35 lb. forged steel
heavyweight. It is a high quality German plane, but I think the adjustable
base feature necessitates a lighter weight. I wonder if the chattering is
simply related to it's light-weight design (relatively speaking - the plane
is NOT really anything I would call light-weight).</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The blade is sharp, the cap iron is mated nicely to
the blade and adjusted about 1 mm from the blade edge. I think everything is
in order. But the darn thing still chatters up a storm. Any
ideas/suggestions?</FONT></DIV>

<DIV><FONT face=Arial>BTW, I am trying to plane a curved caul, so I can't
use a flat plane.</FONT></DIV>
