Often my student's cabinet projects needed half lapped panels to compartmentalize interior volumes.  Even in drawers that needed dividers a half lap joint was the obvious way to intersect the parts.  For some educational research credit I set about seeing if many classic woodworking joints could be made "better" using the CNC.  This joint is one outcome of my explorations.   My ramped halving joint slides together easily but closes up tight and snug.  The tapered side of the slot on each side mates to the ramped face on the opposite side of the mating piece.  The joint is kept aligned down the entire intersection. Both sides are done with the same toolpaths with the boards laying flat on the CNC bed.   My blog post about it includes a link to Vectric's Forum where I posted a sample file you can download to inspect if you use VCarve or Aspire.

I think I would really have enjoyed taking a few classes with you 4D

High praise Cal.  Thanks.  Sadly my retirement marks the end of an era.  Thanks to Admistrative interference what is being taught now is just a small fraction of what myself and 2 other now retired furniture design professors taught students.

Missed this thread.  Ditto to Cal's statement.

It may be my age coloring my view, but it seems a whole lot of (something I can’t come up with a word I’m happy with) is being lost. Woodworking? hunting? Fishing? Being outdoors? Working on cars? Etc. I’m not saying no one does these things anymore, but my personal observations are that many fewer are doing these things. Seems like college/university educations don’t cover what they used to, either. I think 4D’s retirement might be a bit of a compliment to him, cause he seems like he didn’t fit in with their curriculum anymore. Just some ramblings from what passes as my mind. 

You are not wrong, Artie.  I could write a book on how institutional memory gets lost as administrations and faculty get replaced with younger souls. I suspect books on that subject already exist though so I'll spare you.   Distractions from the internet have stolen the play time that was found outdoors or in the shop when we were young. Play time that seeded the wisdom that shaped brilliant careers. It explains much of the current state of this country IMO.
