I'll have to give your method a try. Trying to force to ends together by hand with a heat gun or soldering iron is a pretty poor way to join polycord, as it is apparently called.

We set both ends on fire and then put it in the assembly. We did it this way in 2009 and had like 20 long strands of polycord and not one has broken yet but they are starting to stretch a bit. We also threw some extra strands on there in case one broke we could replace it without having to take the whole conveyor system apart.

Looks great Guys! who did your welding?

Students actually weld everything on the robot; some welds look great, and others, well its 18 year olds welding... We are proud of what comes out of our shop purely because it was all made by the hands of teenagers. We have nothing machined.
