My spiral is not nearly so exaggerated. I have about 2" between layers.
I think I'm forcing it because I'm trying to visualize the whole thing at once, and it's only working against me.
If that's not it, then I still have a very pretty spiral, just squatter.

I've been thinking about that.
We originally aimed for the woofer to be around 30" or 32" off the floor. That is ear height for a seated adult.
How important that is to a speaker located in a baby's room is questionable, but still, what the heck.
But that was when we thought the end piece will be on the ground. Then it was decided, with no change in plans, to hang the speaker from a center mount. So the bottom will be off the ground.
The way the plan was drawn up, I think there were supposed to be 8" or 9" between layers.
But if the thing is a little squatter, that might not be a bad thing, since the structure will be off the ground anyway.
Not to mention that in the baby's room, 32" off the ground for the woofer is not necessarily critical anyway.
Is one speaker all together? Do you have it together with duct tape or with PVC glue?

i also think it won't be a big deal if the spiral is squatter, for the same reasons k.w. had.
still, it's puzzling that it appears to be that much compressed. i would guess it's supposed to look pretty close to the drawings. i suppose once we see some pictures we ought to be able to tell what's going on.
i will wait with patience, master po.
/andrew - wishes bruce lee had gotten the part instead of that carradine clown

OK,
One has the 10 middle pieces duct-taped together. The other has 2 middle pieces. Not too long now. However, I've gotta call it a night. Stick around for another half hour so that I can get home and post the pictures.

Setup seems well put together.
Whatever happened the clay one?
How long did it take you to knock the setup together?
Looks to me like you might have some sag in those duct-taped joints. That might account for the structure being a little squatter than planned.
Glued, they might be higher.

You're probably right about the tape. And I'm sure one or two of the pieces are just poorly put together. Too many lines to choose from. When I actually assemble it, I'll use a red pencil to mark them.

The clay sleeve, sadly, never made it out of production.
The jig took an hour or so to build (hand sawed and electric drilled). Then it broke when the saw came through too far and whacked it on the way back. That's why there's that 2X2.

Well, you made progress.
The thing should work the way it's designed.
Looks like the gluing part might be trickier than we thought.

Think: subassembly.
Two pieces at a time. Let them cure for a day. Then proceed with the remaining pieces like that until it's done, a few days' easy work.
Now I have to figure out how to stuff the things. It's been so long since I designed it, but I think I need a half pound of stuffing per cubic foot.
How many cubic feet did we end up with, total? 3.5?
That sounds about right.
First things first, get the rest of the pieces made.
Really first, a little sleep. I've gotta make French toast tomorrow.

hey, an 11° turn on a 6-38" cylinder is about 5/8", right?
That's what I've been doing, and I never double checked the math.

I do think this is one of those things that you end up doing a little bit of work on for several days.
Come to think of it, most speaker projects tend to be like that.
See ya tomorrow. You want me to call up about glue alternatives?

Thought it was a 6.25" cylinder.
It is 5/8" on a 6.25" cylinder.
Let me check for a 6 3/8"-can't be much more.

Since you're offering, yes. I mentioned earlier this evening that I have a tube of Plumber's Goop.
kelticwizard said:Yup. 0.611" inches on a 6 3/8" cylinder.
5/8" = 0.625.
Close enough.
Whew.
Thanks, and signing off.
