Wayne,
In your second to last photo, it looks like an added piece of solid timber (maybe call it a nosing or forefoot?) between the base of the stem cap and the fore end of the keel planks, right there at the last (foremost) piece of bottom plywood planking.
Howard,
I can understand you not wanting to remove any more of the keel plank material than necessary and I certainly do not want to lead you to do same (I do not even have my plan set yet). But in your last photo the fore end of the keel planks look too "fat". Right there at the aft end of the stem where you cut "cheeks" off of the fore end of the keel planks with a hand saw, it looks like a transitional "rolling bevel" needs to work it way further aft, efeectively thinning up that area of the keel planks, i.e. the same area I mentioned above to Wayne where it looks like he added a piece of solid timber "forefoot".
rswenson,
Tricky area of the build, indeed!
