Go to the next WW show and get that guy from IN-LINE

Folks -

I have a 4 equally sided pyramidal lid, apx 14" square, that rises at an
angle of 25 degrees - how the hell cut accurately and glue it up?

Based on the compound miter calculator (
http://www.scarletta.net/WoodJoy/compound_miter.html ) I need to set the
crosscut at 42.19 deg and the bevel at 17.39 deg.
