Chapter 4 - Welcome to Building bulkheads
Started 5/18/2003 finished 10/5/2003 Hours to complete:66.5
I took my time so that I could learn, I had never worked with fiber glass and epoxy before. At this time I feel more confident about working with these materials, and I am having fun too. When I first got the foam out to work with it I couldn't believe that it would be strong enough to do the job, will I was wrong it's amassing!

Hinge method used to assemble the IP parts Added stiffener ribs.
After I glassed the stiffener ribs I found a problem, the glass has been pushed away from the foam, so I sanded it and put on a replacement peace of glass.
