Yeah - I didn't measure it either - 0.015" implies not 0.016" or 0.014".
But actually it's more like "About of 1/3 of the 1/16" I need - maybe not quite"
I did spend a little more than an hour hand sanding away with 60 grit on a sanding block. 2 ends on 2 panels. The straight edge did show me I made progress. In hindsight I should have just tried to force a bow like I'm doing now. We'll see how well that works...
