>I haven't had any experience with that particular design (or even read that book), but that does looks like an interesting idea, for sure. I'm just posting some thoughts on it, take them for what they are worth...
I would bet that it's simply a slot mortised through the center front piece that the bolts fit through, which would allow the entire front piece to slide, so you can close up the mouth.
The "key" on which the center piece slides (the square part you see on the front that is part of the side pieces) - I would imagine for simplicity of construction that it continues through the back center piece as well, but that piece is simply glued into place. The fit would have to be quite good to keep it inline with the side
I can't see any real problems with the design myself - especially in a Krenov type design. I'm not as sure it would work as well with a traditional style throat because of the need for shoulders to hold the wedge - it might want to work correctly unless quite a bit of thought was given to it beforehand.
For a traditional throat design, WoodSmith #47 had a pretty neat idea where the bottom front portion of the plane was moveable, and held in place by tightening a knob - I've included a blowup of the cover picture below. The knob has a bolt epoxied into it's base and the shoe at the bottom has a threaded insert in it that the bolt threads into. I think that is also an interesting idea.
I agree with Steve Knight on questioning whether a high angle plane requires an adjustable mouth - but I still might have to try make one like you've shown someday to see for myself. Thanks for posting, and do keep us updated on your progress!
