    More progress on roof

    I have done the trickyest part of the roof now. Attached the plywood for inside covering. One piece of ply to install before done. Will start on making the eyebrows today. Have bought some sheets of divinycell and polyester + hardener. Have also installed fans for ventilation. But can anyone give me a hint about what the cables are for? Three cables, but I dont know which one is the positive or negative. And what is the third cable for? It is computer fans, 120mm.

    Once again Ivar I'm amazed. Great work!

    I'd guess the red wire is hot and the white is ground, but not sure about the blue wire unless it's for reporting the fan speed.

    A true piece of art Ivar.

    Your fan connections have 3 wires so they can run off a standard computer motherboard and receive speed variations depending on PC temperature. So you'll have 2 leads for power i.e. Red/Black or Brown/Blue and a 3rd, which is usually yellow that is used by the mobo to vary speed. In your case for the overhead exhaust just connect the two power leads to a 12v source.

    BTW, the Blue should be the negative.

    Thanks guys. Doing my best here

    Will get the fan-wiring correct now. Thanks for the information

    Did start on eyebrows a couple hours ago. But that was not so easy. Have to think it over again. The divinycell I have got was wrong for sure. So it is useless. Not so easy when you order parts from your hardware supplier and get something that you not ordered.

    So maybe I just start with the painting progress now, and let the eyebrows wait a while. No rush with it anyway.

    I am looking so much forward to start with the wiring on the aft-panel and get some sound in the loudspeakers. Have also bought a heavy-duty contactor. Bet you cant guess what I am going to use that for
