This is bascially the same method we'll use for the replacement canopy. This is a mold we used to make Texan cowls for the old House of Balsa pylon racer.

The mold is mounted to a base, which has holes strategically drilled through it to suck the plastic down over the plug. The bottom of the base is lined with foam tape to ensure a good air seal. The base is then placed on a platform which has the vacuum attached to it (such as a shop vac), which also has guides to hold the mold in place as well as the frame that will have the PETG stapled to it. After the PETG is stapled to the frame, it is placed in an oven until the plastic starts to sag. The vacuum is turned on, and the PETG frame is immediately placed over the mold where it is held in place by the guides until the plastic cools. Then its just a case of trimming the new part. [8D]

Jeff, I already have a couple of PETG sheets cut to size for the cowl mold, we may as well make those up too.
