Thanks!
I started making the glass fiber fairing a couple of days ago, the plan was to make a negative mold on the styrofoam plug to cast the real fairing in but since I am a bit pressed on time with the race coming up in less than two months I decided to make the fairing directly on the plug instead.
To keep the polyester from melting the styrofoam I covered the plug in both tape and plastic foil, I was a bit nervous since I hadn´t done this before and on top of that had decided to cut some corners with the directly-on-plug casting.
After four layers of woven glass fiber put on two layers each day with time for it to cure in between it looked like this. I let it rest until today and after an 18km night run with a friend I decided to see how it turned out.
Not bad at all! Much better than I could possibly have guessed in fact.
I have only trimmed the fairing sides with an angle grinder so the fit against the frame will be better later when I have spent some more work on it, it looks to have a very snug fit against the top of the tyre but there is >5cm clearance which is good since the spiked tyre will need some extra space.
I haven´t decided yet if I should leave the opening as it is or block it off with a sheet of aluminum, I would appreciate suggestions from someone who is into bike aerodynamics about this.
Anyway, I am very pleased with how it turned out. Some glass fiber putty, a bit of grinding and a layer of 2K paint and it will look even better.
Cheers!
