Re boxwood plane
That's great, sounds like an enjoyable course!
 I have 3 of Krenov's books plus a few other plane making texts (Finck,
Dunbar, Weygers, Kingshott, etc )
So you didn't use a laminated build, you cut it out of the solid?  I love
the look of traditional (not laminated) planes.
I'm interested in the small mitre planes that Bill Carter makes from the
brass backs of old Sheffield backsaws.  Quite lovely.
