BOLTS!!!!
It suddenly came to me, about a minute ago:
I don't want Ts. I *REALLY* don't want to deal with Ts.
And, I agree that friction fit pipe probably will not hold without some
sort of support.
However, we could use BOLTS!
Drill a hole through both walls of the pipe, so that they line up. Do
this at each end, and drill corresponding holes in the flanges of the
corners. Countersink the holes on both sides, so that the bolts and nuts
don't stick out past the surface of the plastic.
I would be willing to make some (or all, depending on how many we need)
of these and bring them with me to whatever event we do this at
(assuming I come).
And after writing this post, I realised that this limits you to 2
dimensions. There is a way around this: drill more holes in the ends of
the pipes, offset by 90 degrees (or whatever) from the other holes.

| Good idea. I think there's a better way though. Simply use PVC cement. Instead of completely coating the inside of the pipe with cement, use only a few drops. This will secure the pipe strongly enough that it can be twisted free at the end of the (...) (21 years ago, 8-Jan-03, to lugnet.org.ca.rtltoronto)
