Mornin Jerry,
When we get the panels shipped to us they come in 4' x 4' size. But we are building protype office machines/ equipment and traditionaly only use smaller sizes. We can shear it up to 1/4" and then we quite often use double sided sticky tape to afix it to our surface plates on our CNC millers to create whatever shapes our needed.

Were you planing on using 1/8" thick stock and make your own frames ?

Scotty,

Thanks for the info. Just to make sure we are talking the same sort of product I'm looking at the twin walled poly carbonate sheets as shown in the link below.

or
10MM Twin-Wall Polycarbonate 4' x 8' sheet

The numbers I see on these are like 8, 10 and 12 mm. I'm assuming that is the thickness of each of the walls. If my math is correct 1/4" would be like 60mm. I'm thinking you are working with solid sheets.

I am planning on building my own frames and routing out rabbats for the sheets to fit in. I might go with 1/2 round across the sheets to give it that divided look.

1/4" = 6 mm

Judging by the description I see there, the thickness is overall. So, the 10 mm product is about 3/8" thick including both surfaces and the airspace.

Defective,

Never said my math was good. Thanks for the calculations.

no problem...

I live in a metric country next door to a non-metric country. This means I spend at least half of my productive time scratching my head , trying to figure out why my tools seem to have trouble fitting my materials. Then I sit down, have a coffee, pet the dog and look at the tools and materials. Next, I think up excuses to hide my stupidity as I carry on with the other tools.
