So it's been a while since I've had to fabricate something from scratch, and the time has come to finally do something about my fan shroud. The 350 has been known to run at 240* on a couple of occasions and with a trip to Big Bend National Park planned for this spring, I cannot afford to overheat in the middle of nowhere.
After struggling with sheet metal vs. modifying a stock shroud vs. making something out of whatever I have on hand, I decided to try to make one out of fiberglass thanks to this thread: https://forum.ih8mud.com/80-series-tech/597038-homemade-fan-shroud.html
My needs are a little differrent than the OP above, so I took his idea and made a few minor changes. I started with a cardboard and duct tape mockup just to visualize what I had to build.
Then I went on to make a small scale prototype to make sure I understood the materials and the concept. This is my first time messing with fiberglass, so I wanted to experiment a bit before I jumped into the project.
I got good results with the test piece so it was time to make the full-size form. Using the same basic procedure as the other thread (measure and cut out fan disc, design battens/hold down system, and stretch speaker cloth to make basic shape), I made a frame to include my attachment rails and a shelf on top for tools. More on that later...
