Guys, read the entire information. Go to page 13-14 to see how to handle small flanges. Also read page three on the bottom to see that you do not support anything on the Zodiaq but on the seperate support.
This is so much like the Corian specs.
If it is not designed for the DuPont specs it will be almost impossible to build to them.
I know it may hurt, but you must talk to and work with the DuPont tech guys with this. I know Vince in Del and he will help you make this work. Please call him!
