The jig is up...
...and running! (couldn't resist)
One quick question.
I'm assuming that I rotate the pipe 180-11° after each cut. I should ALWAYS rotate it -11°, right?
That's for one enclosure. For the mirror enclosure, should I then rotate +11°?
Thanks
Dave

Re: The jig is up...
Damn, you're killing me with these questions.
Let me go take a look at something to make a qucik model. Your questions have exceeded my powers of visualization. 😕

ok... I'm not sure that I got this right.. but I think this will work.. rather than cutting and twisting 11 degrees for the next cut.. You could make your cut at 5.5 degrees for each side.. (assuming that were not to late). The jig that I suggested is designed to provide a 22 degree angled cut.. rather than making a vertical cut.. make a cut at 5.5 degrees. this will make a compound cut.. resulting in symetrical pieces which ought to work for both left and right speakers.. again.. I ain't positive.. but I think its worth a try.
well, look at it this way: rotate it the same way every time for one enclosure, then rotate it the opposite way every time for the other one.
in other words: all the pieces should look exactly the same for one enclosure, and should look just the opposite for the other one.
make sense?

If I'm right about the nature of that compound cut ...( big if ) you should be able to rotate plus or minus 11 degrees for your right and left speaker.. I too, am havig difficulty visualizing this cut... seems like it should be simple.. but it twist my brain in a weird way.
Should you rotate the piece 180°+11° or 180°-11°?
That might depend on whether you are rotating the piece clockwise or counterclockwise.
Answer coming up.

um, yeah...WAIT NO!
i think that will result in...2 of the same thing.
upside down will not make it opposite.
print out my diagram and turn it upside down...see if it doesn't spiral the same direction.

The early results will be in on Monday morning or late Sunday night. I have a command from my bride to get these things done.

Yeah, this is a toughie. That's gotta be the solution, though. Let's see what the wizard has for us.

That one was definitely a joke, bro. 😉 Sorry for failing to post emoticon...
Okay, I'm trying to set this up:
I am assumint that your first cut has the long side, (7 3/32"), on the right. So that after you cut, the short side is on your left.
When you rotate the piece, the long side is now on your left. Are we together so far?
Then, the mark for you to cut 11° should be on the right of the centerline. 5/8" on the right of the centerline, as you look at the pipe.
MS Paint picture coming up.

Pondering question of how to build the second one mirror image...
Answer to come as soon as I think of something, which might be awhile.

Your pictures look like the duds I cut (duds ccos they were poorly cut, not because they're wrong), so I'd say we're on the same page.
My analysis of it has to be correct. The 22° is what makes it into an octagonally-shaped circle. The 11° is what makes it into a spiral.
Holy moly.
What if each -11° turn actually produces the mirror piece? In other words, every other piece cut produces a segment for its respective enclosure.
The corollary would be that I should actually alternate the 11° + and - with each segment.
Yup. That's it. I tried to test it on a toilet paper roll, but it won't cut as well as PVC! It smooshes down! Grr....

I still think that if you make the 5.5 degree cut to both sides of the segment you'll be able to rotate plus or minus 11 degrees.. allowing you to spiral up in either a left or right direction. but like I said.. I could be wrong.
Alternate + 11° and -11°? I don't think that is a good idea. I would cut them all one way and see about mirror imaging.
Actually, now that I think about it, the way to do it is to reverse the position of the green line-put it on the left of the centerline for the second speaker. However, I would cut them all one way for the first speaker first.
The confusion of alternating would be not mind boggling, but mind exploding.

MS Paint image coming up to show that second speaker needs reversal of red centerline and green 11° line.
