Ive ran into a problem. I have a 77' bonneville core and need to build a shroud for it that will be able to hold the weight of the core. Its going to be mounted on the top of my case by the fans. My problem is im low on money and im not too sure what can be used. Ive tried some fiberglass sheets and it was too flimsy (made it using the glass and resin), I do have a few street signs laying around which I could cut and use but I have no idea as to what to cut them with.
