Hi,
another thought...

I found somewhere (in an old shaper article from the '50s found on the net) that the front/rear position of the cutter tip with respect to the clapper box makes a difference.

When the tool enters the metal, there is indeed a strong resistance.
If there is some flexibility in the tool/tool holder/clapper box, there is a deflection of the tool and/or the support, and the tool tip is dragged back.

If the tool tip is in front of the vertical line passing through the "virtual rotation point" around witch the deflected tool appears to rotate, the movement of the tool tip along this circle tends to force the tool more deeply into the metal. (There is something very similar with lathe tools).

This creates more drag, then more deflection, then more drag, and so on, until a kind of equilibrium is reached (or maybe a "waving" relaxation movement is created ???).

On a small machine, it could well affect the movement, except for very small depth of cut, especially if there is little momentum at the start.

(Sorry, I'm unable to find this article again).

This is an advice from somebody who have never touched a shaper, so, please, take it with the required grain of salt !

PS. Rick, I've seen your videos, it's a very nice machine !

Pierre.
