Hi Patrick,

David gives a very good description of his plane’s geometry above. And clearly he is in good command of the process.

In our own discussion, the formula works as stated for the LN or LV configuration. For David’s configuration, we don’t need to use the formula because the effective cutting angle will simply be the plane’s bedding angle.

Your statement is absolutely correct, provided one substitutes (in David’s configuration),

Sin(cutting angle perpendicular to the grind) in place of

Sin(bedding angle).

However this substitution will yield the trivial result that the effective cutting angle is simply the bedding angle (in David’s case).

Apologies to those who got this far.

Wiley
