In the meanwhile I made a whole into the doors platework, behind the speaker.

You can see the windowglider. Just nog touching the speaker.

Made some more parts, to fill up the other wholes.

On the background, there's a alu plate of 4mm thick. Very hard and strong.

In the middle you can see 2 Carbonkevlar parts. I made em as thin als possible .

On the foreground you see 4 little rings I made, to screw the doorpanel extra tight.

If you look to the second on the right, there's a little rubber he pasted on. On the place where he screwed it. This to prevent resonance.

On the picture you see a little pole picking out. That's MEGA IMPORTANT.

Behind the speaker, there'll be another screw, so we can attach it even more in the middle.

DSC02505_resize.jpg

Everything mounted:

This won't be the end of the door. I has to make some tiny wholes airtight, but that won't go untill the has all the material to fill up the sound.

All I makes, will be filled up with this material. What exactly I going to use, he's not sure. we'ill keep u informed.

As you can see, I putting a lot of work into all this. And more work is coming up so the sound won't be lost...

I think this is a type of work, that is underestimated be many people. But the work will pay of in the end, that's what we are sure of...

As you can see, het got the disc in there again. Disced a ditch in there so I gots some place to get the overflowingin leather away.

The alu and the pole I got on there so it all stays equal when it gets overlayed.

The bottomsides of the doorpanels will have to be done in CARBON FIBRE.

So a dificcult object to get in the Carbon fibre. But we must admit, it's done nicely..

Many time was put into preparation the prevent the CF - overlay to got wrong at any place.

DSC02737_resize.jpg

DSC02740_resize.jpg

DSC02738_resize.jpg

This annoying little side was one of the many things that could go wrong.

DSC02741_resize.jpg

Also, I was satisfied to get the little lamp in there. makes the piece a bit more interesting then one big lumb piece.

DSC02743_resize.jpg

This is the ditch I disced into the panel. For those who don't get the picture. When it's all done, the upperside of the panel will be overlayed in leather. Then I needs a little space the get rid of the too much leather.

To get a nicer finishing off

You see on this pic that everything at the bottom is in CF..

DSC02739_resize.jpg

Now the big work is to get it all nice and flat. Put some more layers of epoxy on there till it's all nice and smooth.

so, lots of work and patience...

After firmly rubbin' the epoxy, I added another layer op expoxy.

Maybe it's not so visible on the pic, but it's quit flat already.

4th layer of epoxy.

Now it's important to rub the last layer good. Start with an 800 and end with a 2000.

I also found the same black leather to cover the panel like the original one.

A couple of years ago, my wife was making ( read: painting) christmasballes, to hang in the christmastree. She also hooked on making special things

When i looked at the plexy balls, i know, that sometime, i could use it for another project Well, ladies and gents, IT'S TIME

These are the plexy balls, you can buy 'm in every size. (according to his wife)..

:D:D:D

A old friend of my Earl Zausmer build 12 or 13 years ago something like this.

DSC01990_resize.jpg

DSC01991_resize.jpg

Then I made a hole in the bigget bal, so the little one stands a bit 'in' it

DSC01993_resize.jpg

On this pic you can see the ball with the speaker, stands a bit further away. I did this on purpose.

__________________They will go on horizontally against the A-pillar of the car. I made already 4 copies in polyester.

Made a hole in it, and taped it all with some tape.

Then I polished it all a few times, so when he takes them apart, no polyester stays sticking on the plexy.

It also took some work to make the fiberglass so smooth with as less airbubbles as possible.

DSC02018_resize.jpg

DSC02019_resize.jpg

There are 2 layers of polyester now, what should be strong enough. Don't want these things to get TOO heavy.

Made another 4 alu-rings that will come in there. So it will be possible to screw the speakers tight into the alu rings.

It also popped to mind that it would be cool to cover this in CF, but that's almost not possible.

The polyester balls are ready, and look good.

On the right bal, you see a piece of polyester go loose from the plexy.

Ticked it with a hammer.

IMG]http://i82.photobucket.com/albums/j272/robola/DSC02020_resize.jpg[/img]

removed the plexy (upper)

DSC02022_resize.jpg

Removed the lower plexy.

I made them each the same height.

First I leveled the plank. Then rubbed it in one time...

DSC02032_resize.jpg

DSC02029_resize.jpg

Put them together. Mesured a couple of times how much the tweeter must go backwards, and put a piece of MDF wood under it, and glued it together.

You can see I put a little filler to fill the wholes in the polyester.

DSC02036_resize.jpg

DSC02035_resize.jpg

I made the smaller ball crossed over in the big ball. It seemed cool...

DSC02038_resize.jpg

Before I going further with this, I needs some alu, which my friend is going to suply. So I started making some bridles to hook them up to the A-pillars. We can assure you, a f** job which will take a while

Got some alu rings from 10mm thick to center the speakers..

DSC02058_resize.jpg

The rings must go into the whole, and got tightened at a specific depth.

I can asure you, i was on this for HOURS.

Screwed each ring with 3 screws.

As you can see, I made the side of the ring a bit raw, and put some slots in it. I did this, so the polyester can flow nicely and everything will be fastened tight.

DSC02065_2_resize.jpg

On this picture, you can see, that where the screws are, hI pasted a little piece of rubbingpaper. To keep it from moving.

DSC02063_2_resize.jpg

DSC02064_2_resize.jpg

In the little ring for the tweeter, I milled out a little hole. for the cables.

I already kept the balls in the car, to see if they were straight, and how they would look on the dash.

DSC02068_2_resize.jpg

This work seems very simple, until you do it.

To know if Left and Right are exactly the same, I took out my laser.

With that thing it's actually very easy.

You place it in the centre of the mid. I got lucky it fitted right in .

DSC02094_resize.jpg

You turn the thing on, and aim where you want it.

DSC02102_resize.jpg

In the background you see some trophies what i won in IASCA COMPETITION .

Include;EUROPEAN CHAMPION and BEST OF INSTAL.:

Here's how i fastened the christmasballs against the A-pillar.

As you can see, i put in a big fat roundel in the biggest ball. This was so I could hold it all firmly.

Also you can see that the hole is bigger than the screw. i did that so i can aim it.

The head of the screw I cut off a little, cause I hit the back of the speaker.

DSC02119_resize.jpg

Upside the hole, you can see a little slot. i made that to get the cables through.

DSC02117_resize.jpg

This is the Iron trolley who is screwed on the A-pillar.

DSC02121_resize.jpg

This is the adapted A-Pillar.

DSC02122_resize.jpg

So it looks in the car. The A-pillars will be covered in black alcantara.

DSC02127_resize.jpg

DSC02128_resize-1.jpg

It's tight, LOCK TIGHT !

DSC02129_resize-1.jpg

Here the christmasballs of he's wifey, in the car

DSC02130_resize.jpg

DSC02131_resize.jpg

DSC02133_resize-1.jpg

The original focal grill's

DSC02135_resize.jpg

You may also notice that the wooden trim in the car is changed by alu...

i also made some in CF, but i didn't like it, so sold those ones, together with his wooden.

Wanted some contrast in the interior.

That's why the polyester balls will be sprayed in the silver, like the trim.
