Hi guys,
I was working with PVC pipes for making a mock chassis recently, and i wanted to make it pretty close to the actual cad model. I tried a few things to attach the pipes rigidly to each other at joints using :-
1. PVC solvent (used to make joints leakproof in plumbing) - not strong enough
2. Duct tape - holds, but is not exactly as rigid as i'd like
3. Plaster of paris - Did not adhere to the PVC surface well, and was really brittle
I also tried melting the pipes into each other :P , but it was a bit of a disaster.

I could not use any fittings due to the oblique angles at joints.
Has anybody else faced this issue?
Can anyone point me in the right way?
