Hi David, Bill, and all,

Invite your comments......It strikes me that the goal for the capiron face is to make it consistent—repeatable—with respect to total backpressure = friction+effective angle.

Bill has established two points:

1. The capiron works by backpressure on the shaving taking effect at the cutting edge. Meaning, for a given wood, shaving depth, setback, etc, you need backpressure = X for the capiron to work. If the friction is reduced to zero, say, the angle would in principle have to be increased to bring us back to X.

2. As between friction and angle, angle is dominant by a lot.

And David has pointed out, he doesn't see any wear, for all his planing.

Can we conclude from the above, that the best we can do is follow Warren’s advice to keep the face of the capiron polished enough to make the friction component repeatable?
