    My E39 Bezel Attempt

    This is my first fabrication of any kind, so don't expect anything fancy! But anyway, I shall show my progress (or lack of) as I do it.

    The screen is an 8" Widescreen from LinITX (same one at CarTFT). Here's a picture showing that the screen fits in the gap:



    I bought 2 DIN adaptors. They fit the top and bottom snugly, so the width is consistant:





    I put them on top of each other. This has given me exactly the right width, but double the height. Here's them glued together using Aroldite (this can glue ur bum cheeks together forever).



    Amazingly, the window is a perfect match for the screen's opening! Look:



    I'm kind of playing this by ear, so the next step is to cut the construction to the right height so that it will fit, then it will be P38 time (bondo)

    Any hints and tips at this stage would be great!

    And here's some measurements for those that want to know the size of this screen:

    Total size WxH = 189mm x 120mm
    Visible screen size WxH = 178mm x 108mm

    Please say that isn't Aroldite on the screen on that last picture?

    yeah, it's easy to take off... you just cry a little in front of santa

    no, it's aroldite on the bezel, I had it laid on a flat surface so it would join perfectly. I only rippsed off the newspaper from underneath, and I haven't got round to tidying up the glue excess.

    do you have anything reinforcing the araldite? it is epoxy and not structural by itself. I would add some sheet of fibreglass tissue to the back and cover it with more araldite if i were you.

    I really can't wait to see if it will fit, and how it will look in there...
    Nice work so far though.

    fanks scouse, good point!

    I've just bought two types of fiberglass stuff, but didn't know how to use it yet. I've got an idea now tho.

    I know that there will be some places where I will need to fill a lot. would using just p38 do the trick or should I layer it with some fiber/epoxy and build it up layer by layer, then use e39 at the end to shape and sand?

    e39 is your car dude! don't you mean P40?

    I get mixed up over which isopon is which. One is filler (p40 i think - red pack anyway) and one is fibreglass - blue pack (maybe P38).

    The fibreglass is a polyester resin with chopped glass reinforcement. Personally i would prefer epoxy and I am very tempted to use some of the thick epoxy we have in work. The other stuff is non structural and should not be used for strength or thicker than 1/8th" or it will crack. The glass stuff is pretty strong but messy. If you can afford the araldite you would be better using the some chopped glass mat (not the surface for strength) and aralddite matrix. This is nice and easy to work as araldite is quite runny and the mat can be cut to shape.

    You can get 3 types of glass mat:

    cross ply woven (thick and more difficult to drape)

    chopped strand - not exactly structurally perfect but very good for our purposes and random directions mean good strength in all directions. Also nice and thin and easyt o handle and better than you would think for strength.

    surface tissue - again chopped strand but very thin. Used for laying a smooth surface over coarse stuff. Can be used for structural reinforcement but obviously more layers are needed and the short fibres limit strength.

    hehe, it was getting late. I saw that reply and went to bed, rather than type more crap!

    The stuff I have is a quick sand filler (p38 black tub), so I guess I can't do a big lump of it. Along with that, I bought a fiberglass kit from halfords. It contains a bottle of fastglas resin, an activator and a sheet of fiberglass which looks like chopped strand (each strand is short and randomly directed). Finally, I got some glass fiber tissue.

    So I guess the way to do this is as follows:

    Layer with thick fiberglass slowly until the structure is shaped, then final layer(s) with tissue, once I have the shape I want by sanding/trimming, use P38 and sand for smooth finish. correct?
