Building a vintage bike scene in Colorado Springs
When I did the original fiberglass cowl the mold collapsed as the resin heated up so I had to bondo the hell out of it. Eventually it got a few cracks that I couldn't stand so here I go again building a new cowl. I learned a lot on the last one so I'm sure this one will turn out better.
Foam mold
Wrap the entire seat and cowl in cellophane to hold the foam cowl, protect the seat and so the fiberglass will release once complete.
First layer of mat on and set, let it dry and sand everything smooth.
Sanded smooth and ready for 3 layers of sheet.
Getting the sheets ready
3 sheets are now applied, I rotated each layer to add strength by getting the strands to run in all directions.
Now it's time to let it all set up and cure...

Roland, can you take some detailed pictures of the back seat cowl. I'm doing the same thing on my project bike but I'm not sure how to proceed. Did you just drill holes into the seat foam then press fit some metal shims in there? Can I pick that stuff up at the local Home Depot? I'd appreciate it! Keep up the good work.

I welded 2 small tabs to the seat pan a little inside from the edge. That way there could be a little foam between the tabs and the leather. I originally had it set up with pan head bolts holding the cowl on. I just welded a nut on the tabs so I could thread the bolts in to the hold the cowl. All that stuff you can get at Ace. The new set up is quick release so I had to weld new tabs to accept the quick release, all that stuff is special order.
As for the leather, it just has a reinforced hole in it with stitching around it so it wont fall apart over time.
I hope that helps!
