Years ago I made first "handmade" tool which was a hack of the Krenov Style hand Plane... using a Hock kit, ... didn't realise the dowels were supposed to be in the cut off area.
I would never consider "facelifting" it even with a laser, however, I appreciate your take and the detail you went to to present a thorough "how to".
If your first cut is too short... Take the second cut from the longer end... LBD
