Focussing on the key point
Response To:
Where did the ball go? ()

The basic point I was trying to make earlier is this: Allowing the cap iron to extend to or below the plane sole isn't absurd to the point where we can dismiss it out of hand as you seemed to (and my apologies if I misread your argument).

You replied by citing an example (7 mil shaving with 5 mil setback). While it's true that that isn't viable on multiple levels, it's also a strawman in the sense that it didn't address my point. The "critical configuration" that we need to consider here is the equivalent of a 5 mil shaving with 7 mil setback (assuming 45 deg bed angle), in other words the converse of the one you cited. If that configuration is workable, then it may be worthwhile to profile the cap iron.

I've tried putting the cap iron in the plane of or slightly below the sole when edge-planing (such that the corners are a nonissue), mostly out of curiosity than any real need [*]. Planing forces were noticeably increased, but it works perfectly well.

Again I'm not saying that this is something we need to do (at least not in any situation I've encountered), merely that it isn't blatantly unreasonable to the point where we should dismiss somebody else out of hand or dismiss them as lacking knowledge for doing it.

[*] Since I expect you'll ask, when I measure setback (which is very rare) I do it using the ~1.3 um/pixel camera setup that I outlined in another thread.
