So, for some completely delusional reasons, I'm still curious about the possibility of making a CHEXX hockey replica.

It turns out that the dome is really just an acrylic skylight.  I was wondering if anybody had really really accurate mesurements of the dome off of a super chexx?  Including the flange, and the step ring aroung the bottom (don't know what it's called)
