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
