Shucks
Sorry. It's probably not going to happen this afternoon, either. One of the joints on my mount didn't dry as quickly as I had imagined. It's going to need another day to set.
Tomorrow...

To be honest, Kneadle, I am not sure what you are saying here. Is the cardboard part of the outside wall that separates the inside of the enclosure from the outside? Or is it merely a platform that can have leaks because it really is not part of the enclosure wall?
If the cardboard is part of the enclosure wall-separating the inside from the outside-I would think that you would want something stiffer than cardboard. After all, you can experience loss through even a small part of the enclosure.
Maybe a half inch piece of plywood or some such would be useful.
Sorry to bring it up at this late date, but it has been on my mind.
Looking forward to the unveiling. 🙂
CAD drawing
Kelticwizaed;
A little off topic, but I would like to know what CAD program you used to do the drawings on post #241? They look great!!
Thank's; Doug😀

If you take a look at some of the earlier pics, you'll see that I'm having a hard time describing the obvious.
The top of the tee needed to be sealed off from the rest of the pipe, and it is just large enough a compartment to store the crossover components for easy access. Therefore, I had to seal the enclosure without using up the space of the top of the tee; otherwise, the crossover wouldn't fit.
I used the cardboard basically to hold the PC-7 epoxy. From the inside of the tee, I kept adding layers of epoxy until it was fairly thick and rigid. That way, I sealed the enclosure and kept the top of the tee free.
I COULD have accomplished the same thing with some wood, but I used what was at hand. I'm fairly confident in the results.
So far, I'm still messing around getting the mount built. It won't be long now.

Re: CAD drawing
actually, that was my drawing. 🙂 it's a 3d model done in autocad r14. not a cheap program, although you can get a 'lite' version i believe.

Preview
I'm 99% done, but I am having serious problems getting the things to mount. There's still some finishing to do, too, but I thought I'd give a preview in lieu of the promised completed project.
As far as mounting goes, my joints keep breaking,
and I'm not sure if the integrity of the bamboo pole can survive drilling. Brainstorming now, but suggestions *sigh* are welcome.
😡
The picture is poorly framed on purpose, just so as to maintain a little mystery. Enjoy!

In all my long experience of speaker building I have never seen a system as cool as those!!!
Well done😎 😎 😎

I just showed the pic to my wife (all the felt she has laying around was part of my inspiration for suggesting its use). She really liked them. Called them "wormy", then i said they were caterpillars -- then she said "potential butterflies"
dave
they're awesome!!
you are indeed a cunning linguist! (and i'm a master debater...)/andrew - has been waiting a long time to say that

Keep in mind, these are TL prototypes. They're called "The Seraphim." If you know what a seraphim is (see my avatar), and if these are caterpillars...
Hey, Pinkmouse, I read an article today about the universe, suggesting that it might be doughnut-shaped, with the result that one of the stars we see is simply the light from our own galaxy on the return trip around the "doughnut." I might have captured a bit of that with these speakers, eh?
And everyone, please watch for a post coming--as soon as I can mount these 🙄 called "Spiral shaped TL enclosures finished." I'll include all sorts of information and GOOD pictures. Thanks for all the help. I could have never made these without all of you.

Sherlock is nice, but there's a singular description of them in the Bible, if you can stand to open one. Isaiah chapter 6. Fire and smoke and noise.
Anyway, I get really annoyed that everytime I post a pic, the page turns so that no one but the first few get to see it. So I'm gonna post it again.
This is a preview. Enjoy. Don't know why it didn't simply paste in. Computers.

Yeh, I read that idea a few weeks ago as well- I think it was a topologists' idea to try and explain the "missing mass" problem that is currently bothering astrophysicists
I'll have to look closely at my avatar and see if i can see the flash of the big bang produced when I blew up a couple of LM3875s a few months ago😀
Dave (P10)- Steven Hawking is best known for his "Trouser (pants, for our colonial cousins) legs of time"!
Dave(Kneadle)-To get back on topic, If you predrill the bamboo with a sharp brad point wood bit, you should be able to get a couple of 8 gauge screws through the bamboo and into the PVC tubing to help support it😉
woo, didn't know that reference to seraphim. nice. seraphim for the cherubim.
more biblical sound references - the tower of babel (obvious); the angel gabriel; joshua (the battle at jericho)...

I had a hunch these things would look offbeat and different after they were finished, but I had no idea that they would look anything near this spectacular.
These are amazing!!
To make matters even more incredible, they are built according to sound scientific principles. Who would have believed it possible?
To tell you the truth, when I saw the picture of all the yet-to-be-glued pieces lying around the floor of your living room, I said to myself, "Oh boy, he's never going to get this together to look like anything." And yet here it is, just getting ready for the finishing touches.
Congratulations!!
One question: how much of the exterior design was done by your wife, and how much by you?

And to top it off, the mouth even looks a little bit like the mouth of the baby from The Simpsons. 
I hope you don't get sued by the show.
As for the bamboo problem, I would try drilling a hole and using T nuts, available at any Home Depot or True Value type store.

Talk about queer universes--many people now believe that the respective prophets were describing the same things/beings. It's my dissertation topic, just so you know, reader-response theory and referentiality.
pinkmouse said:
Thanks. When I go to the shop, is it going to be called a "sharp brad point"? I have no idea how to distinguish bits, so could you tell me what it looks like? I should probably think of bracing the bamboo so it doesn't eventually crack under the torque that gravity puts on these things. I could fasten some thin paneling to the spots in question to distribute the weight over a greater area of the pole.

Heh heh heh. And the whole project was built with a handsaw, from start to finish. The only other tool I used was a plaster knife to spread the epoxy. And packing tape--lots of packing tape.
All of the design is mine. My wife brought home
The Very Hungry Caterpillar for reference. Then she graded papers while I cut and glued. I even did the fabric shipping. The lady at JoAnn Fabrics wants to see a finished product.
