Now that's interesting. I took a look at a piece of 38mm Delignit scrap in
the shop yesterday and found it to be assembled from two thinner planks,
one with 1.5mm laminations, and one from 1.4mm. I doubt that the asymmetry
was intentional though. I suspect it just happened to be what stacked to
the right thickness. Since I didn't notice it when I installed the block, I
have no idea which end is up (ask anyone), and doubt that I could tell the
difference anyway with the lamination heights being so close to the same.
With maple's higher MOE and crush resistance, especially perpendicular to
the grain, your block ought to be pretty impressive. What drill size did
you use with these for 2/0 pins, 17/64, 6.7mm? 

Any chance these will be available for sale to someone in, say, Kansas?
When you start production, I'd be interested in giving them a try.
