    Display Case- Fiberglass?

    My brother and I are trying to design a sort of display box to mount my LCD in on my dash. We are trying to get the shape of the box to match that of the HUD with all the car gauges. We tried to bend plexiglass by using a heat gun and it worked very well. The only problem is that it is very inprecise. We can't get it to the exact shape we need it to.

    This afternoon we decided that tomorrow we will try to make a model of the display on my dash out of clay. Then we would try to melt the Plexi glass over the clay in order to get the right shape and angles. Angles were very difficult because the dash slopes upwards. Does forming the plexiglass over clay sound fesiable?

    How hard is it to do fiberglass? Anybody else have any suggestions for materials? We were going to just paint the plexi after to match the dash so opaque materials are no problem.

    The display that we are making is fairly small. It's going to be about 8 inches long at the base and 4 inches long at the top. The sides will be a nice gentle curve joing the two. The box will go back and gently mesh into the dash.

    I hope you people can somewhat understand from my description.

    fiberglass

    First, what type of car? If I knew what the dash looked like I might be bale to help. Fiberglass is kinda tough to work with, but probably easier than bending plexi. Here are some links to help you:

    Some of that is helpful. Looks like fiberglass won't be much of an option for me. Is it really that hard? The car is an 87 Mercury Lynx (Same as Ford Escort).

    Oh man, don't count fiberglass out of it. In fact, what you're doing is how you usually get complex shapes with fiberglass.

    It's really simple. Just get some cloth, any cloth, it really doesn't matter if it's not going to be for strength (an old t-shirt is great for this), and lay it over the clay. Pin it down or tape it, just make sure the cloth is in the shape you want.

    Now, mix the resin and harder, and paint the cloth with it. In 30 min or so, it should be firm (takes a few hours to fully cure). The fiberglass shouldnt stick to the clay...

    Put another layer of fiberglass on for the hell of it, sand, bondo, sand, bondo, sand, etc, prime, paint/vinyl.

    It's just that easy.
