One for each box...

I must be weirder than most think know... I like the "chaos" of this one,

Sorry for the ignorance... a couple of questions/observations:..  after all I'm a puzzle maker and not an engineer/seasoned_woodie (seasoned, but not from wood alcohol... hmmm that wood may explain weirder. 
 new style panels from veneer smalls.
  Is it from one sheet or your marquetry (shiit, if it is)?


Do I understand this correctly... did you slip a 12.7mm bearing and sleeve over a 12.7mm shank "normal" bit? If that is correct, did you specifically size the bearing or were you just lucky on the OD. 
Sticking with the "correct theory"... great idea... may be ho-hum to many, but new and brilliant to me. 

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