I cut 12 or 13 rectangle from 2 inch thick pink foam. This foam was purchased at Leow's in a 4x8 sheet.

They will be stacked up to form a full size plug of the finished part

The blue papers are forms cut to the profile shape that I was trying to achieve

This is what the forms look like. If you look closely you may be able to see that each form is slightly smaller than the previous one.

Cut the foam to the approximate shape of each form

Glue them together in a big stack. I used 3M spray adhesive

Here they are all glued up

All glued up and ready to shape

Shaped with 60 grit sandpaper

Lay up a layer of fiberglass, followed by 5 or 6 more layers

The finished fiberglass canopy is painted black and installed on the Cap 232
