Marc,

	OK, now I am feeling like Mr. Wizard, a science guy that was on Saturday 
mornings and showed kids the interesting things about science.

	For this, I would use a perforated aluminum plate cut to the distance of 
rib centers. By using perforated sheet, you do not need access to a device 
called an "English Wheel". This is two rollers that you vary the pressure 
of contact and roll the aluminum sheet between the  wheels. this causes the 
aluminum to stretch and curve. The perforated sheet will allow you to 
manually curve the sheet without buckling. then add the resin/fiberglass to 
this. The perforations will allow the resin to go through some and make a 
better bond. Also, roughen the aluminum with a fiber abrasive pad, we call 
the Scotchbrite.

	How about it?
