Looks great and another good write up.

I don't collect knick-knacks to store on the shelves and not being an avid reader, I could always use something like that as a ladder if it wasn't such a show piece.

 Drilling was a challenge in the places where the 4 degree parts met the top, but worked out ok using an old computer disc drive platter to align the drill. 
Obviously you aren't a one eyed hand-held toolman as you are leading to computerisation (potential CNC).
..... Talking about CNC... 
 The top and bottom cutouts plus the taper meant I wanted templates. The laser provided them for the ends..... 
If you bought yourself a Shaper Origin, think of the fortune you'd save in shekels by not having to make templates out of MDF/ply!

If your first cut is too short... Take the second cut from the longer end... LBD
