Paul,
I have a friend who owns a 3D CAD and CNC business. I had him build the cheek cowls on the computer and cut it out on the CNC machines, otherwise I would have had to carve my own plug and build up the female mold from the plug. Bad news was that even though he was a friend it did cost me

so if anyone is interested in cheek cowls let me know

I've got the mold!!
The mold is made of a CNC machinable poly foam which isn't affected by poly or iso resins, very dense, heavy, closed cell foam which is used alot in building protype hardware.
Nomally when you use a vacuum bag you put the resined peice and mold in the bag, however in order to do that with this foam mold I would have had to make the foam mold smooth by surfacing it with layers of resin a sanding. waxing and polishing which takes a ton of time. My friend told me that I could use the bag itself as the release mechanism so I vacuum bagged the mold ( the bag sucks down into the mold ) and did the layup on top of the bag

It worked great and much quicker but I will need to do some extra work in finishing the outside of the cheeks because the foam has a slightly rough surface, but smoothing that surface is not as big of a deal as preparing and polishing the mold itself.
I just glassed the cheeks to the top and bottom cowl today so I'll be spliting them tomorrow. I'll keep the pics coming
