I got up to the shop again on Monday and Tuesday to help the boys finish the inside skin and start laying out the core. I hope to have the time to spare to get back up there today or Saturday to presumably build the oven and cook this bad boy off. Laying out the 45's was a pain, but the second layer of 0-90's went really well.
The core is bonded with 400 gram film adhesive, which is effectively the same resin that is in the pre-preg carbon layed onto a VERY light scrim (probably polyester). If not kept cold it gets REALLY sticky, so the trick is to work fairly fast and not hold onto the stuff for too long.
