The solvent was the clear winner - both melted the plastic to some extent, but the glue for the Testor's plastic cement didn't really help it bond. The plastic weld just literally melted them together. I was able to seperate both, but the solvent took considerably more force. I think with a better fit (I was just using scraps I hadn't tried to shape to fit nicely together) it will bond completely, and not be easily breakable at all.

So, a total of 6 glues tested, now to move on to some real building!

Remaining challenges:
1 - precise design - I have the general layout, gotta get down to the specifics!
2 - How to join the rollcage to the chassis. 3 things in mind here - 1, for the thicker center cage, putting holes in the chassis, drilling a small pilot hole in the center of the .375 abs, and running a screw up into it. 2, flattening the ends of the .250 abs, and drilling holes through it to attach it to the chassis with nuts & bolts. 3, using round end electric wire connectors which fit over the end of the abs, gluing those, and then bolts through the round end connectors to the chassis.

At this point I'm favoring 1 & 3. They're more precise, and have a cleaner look.
