Here some pictures of the thing I made.

First of all I made 6 of the same plexiglass boomerangs.

I did this in plexi so you can see if something goes wrong.

Made the model in MDF offcourse, then I pasted the 6 pieces on , and held it to the copy-mill





Only this is how you get everything 100% the same.


After that I milled the MDF rings.


De linkse ring is van volkern.




Some more rings, and the plexi











This needs to be put together now, and then it’s finished.

Simple !

This “thing” I made, has a name… and I’m curious for the guy/girl who can guess what it’s called.

The first person may come over here to clean and dust my garage.

Oh my, just went through all pages and the work is out of this world. Outstanding work, but I am stunned by the effort you put into the documentation on the project.

Will be keeping tabs on this thread!! Great thread!

Especially for you, Snox400



A couple of words about the DIAFRAGMA. First I would like to say that I didn't know how this was called too...

As I told before, I had it in my mind to make such a thing for years now. I never bothered to think how this was going to work exactly...this was al about mathematiques, and even in school I hated that crap.

But if you look at it know, it's quite simple.

To explain it a bit easier, I let the top part off.

You can see 6 plexi boomerangs laying on top of each other. You can also see that on the tips there are some inbus-scews of M4, these are the hinge-points.






Here you can see him closed.






Here complete, with the cover on top.
This is the slide, where you open and close this thing with.






In the 6 slots there are imbus-screws. You can also see these are on the outside of the slot.



Now you see it close, and you see the screws go to the middle.




Now it's closed.




You can see there is a hole in the middle, but that's normal with this drawing. It never closes completely.





Some pictures from on the other side.










The meaning of this thing is, that I want it to stand behind the back of the rear seat. You may know that, in the beginning, I traded the normal rear seat for a rear seat with ski-hatch, to get the bass better into the interior.

Because I found this hole kind of BORING, I'm trying to put in a diafragma. Read again: TRYING !!

You also know the amplifier comes before that when it's open, so I need to check and measure if I still have enough place to put it all.

I'm going to make everything out of other materials, about 18mm thick

It also needs to open and close automatically, but that's easy to sort out. The biggest problem is to ensure it doesn't rattle while driving, but I may have a solution for that problem to

Now about the hole (when everything is close up) I think I've found a cool solution for that too.

I'm only hoping for one thing now that I have enough place for this all

Ok Snox400, you were the first to guess this, so you won the grand prize:

Especially for you I won't tidy up anymore after drilling, milling, so you can enjoy cleaning up my garage even more.



So, book the first ticket to Belgium you can find, and get over here! It's nice over here, chocolats, beer and Kim Clijsters and there's Robolop too

This is all very nice stuff, but when are you FINALLY going to show us some pics of this all installed? Or at least some of them!

I have another question: You use the Epoxy by Vos Chemics I understood. But which variant is this exactly? I just can't get the CF out of a mold with that thick cured epoxy on it. I almost always have tiny holes where the CF structure is. Am I using not enough epoxy on my mold?

Oh could I please?!?!?...robolop, not only are you a superb designer/craftsman, you're a genuinely nice guy!

Haha but I am actually heading to Italy in 10 days to see the girlfriend and if I had the choice between learning some milling techniques and seeing her, I'm not sure what the decision would be

But anyway, love your work as usual. I have no idea how you figured our the correct shape/size of those pieces , very impressive!

When I make these boomerangs in plexi, and put a led-strip on it, this will give a nice effect on the sides of the plexi.

But I’m not going to do that.

Don’t let your girlfriend reed all this, she won’t be too happy with you…

Maybe you should try and look for one in Belgium, then you can visit me sometime. So you know what to do…

These will be the final boomerangs for the diaphragm. I used anodized aluminum of 1.5mm thick.

This material is also used on the backside of the Focal Woofers.

I taped 6 plates on each other, and held it to the copy-mill. The uppermill is now the best tool to fnish these things off… hope the disc doens’t go in to tears now .






Here you can see the upperside of the boomerangs.





And this is how the backside looks. You’ll see right-away that I taped some self-adhesive black vilt on it.




I had to do this, so I couldn’t get any scratches on the aluminum when everything opens and closes.

Secondly this will prevent vibrating when I’m banging the install.

Cause the aluminum is only 1.5mm thick, I screwed in some screws with a bit of loctite on it. That way I’m sure it won’t fall apart.



The plexi boomerangs I made at first, landed in the rubbish bin…but they always seem to come back. How is that possible ?
