Running chains on zipties

I would also recommend Delrin. It is sold by Mc Master Carr in several shapes. We are currently using Derin on our 2012 Robot for Chain Guides. Just make sure you have plently of rap on your sprockets.

We usually take those AM tensioners and drill a hole through the nylon pieces and just bolt one half (as in one nylon piece) to the frame somewhere along the length of the chain. I wasn't able to find a better picture of it but you can see the top of the piece in between the 2 middle wheels.

About the zipties, we have actually used them as tensioners before in very desperate situations (like at a demo when we forgot everything else) and they work for a very very short time before the chain cuts through them. We have however had chain run against metal (1/4" bolts) before and it usually is fine.

We used some pieces of ABS sewer pipe to tension the chains on our 2011 robot, easy and it worked well (until the axles bent but that's a story on another thread). Kind of like the PVC pipe suggestion.

Good luck!
