Sepp, your aero cap is looking very good! Very nice craftmanship too! It is hard to realize how much work goes into these until you start to build one. There are many different methods to construct an aero cap and if it can be molded from a mold, then you not only get the strongest and lightest possible parts, you have the ability to replicate the part.

Here are some photos of how I constructed mine. The first photo is of the armature, which as in sculpture, is a subframework to support the final layer of clay. Clay is a great medium to use for it is non toxic and can be changed swiftly. The next two photos are of the clay work progression and the last two photos are of the finished clay model and the finished part. Like you, I built the cap right on the truck. I then removed it and cast the mold, which is two part, one being the roof and the other being the sides and front structure.

I have finally sold one of my caps and am in the process of building it. I have another sale pending. Having been out of work since August, it is time to create myself a bailout, because I won't be seeing one from the Government.

Keep on building Sepp, with each you learn more and get better, that is how I learned too.
