(...) It's really quite fun--part of it is because it's in 3D vs the usual 2D building we do (ie, wheeled/tracked floor based vehicle) and at that, you have to work at any angle (because the pipe is 1D, but you can approach the joint at 360 (...)

(...) So, I was talking with Chris the other day, and he suggested we go straight to doing T's and Y's without stopping for 45 deg joints only as a first event.

(...) I'm concerned that we won't be able to support a track of much length without having Ts to support the structure. The weight of a robot with one or two RCXs is quite significant. I don't think friction fit 2" ABS pipe is going to hold. If we (...) (22 years ago, 4-Jan-03, to lugnet.org.ca.rtltoronto)

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 (...) (22 years ago, 7-Jan-03, to lugnet.org.ca.rtltoronto)

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 (...) (22 years ago, 8-Jan-03, to lugnet.org.ca.rtltoronto)

(...) I'd favour Trevyn's method over cement, because the whole idea is that the track is reconfigurable from round to round. If the cement hardens, won't it be permanent? I dont' really want to be dynamically supporting the maze, because it might (...) (22 years ago, 8-Jan-03, to lugnet.org.ca.rtltoronto)
