Hey Steve, hopefully I can teach the master some new tricks. I've come across this problem with my scratch built hot rod. I use Testors Liquid Cement. CA is simply attaching the pieces together, where as liquid cement bonds the plastic.

Notch you joints using a round file, check the fit against the tube, and use a good amount of liquid cement on the tube edge to get it nice and soft. The plastic will then be melted together forming a strong joint. Now the problem may be with wall thickness of the tube. Take your normal roll cage tube, and find another tube that fits inside of it snuggly. Use the liquid cement and bond them together. Let them dry for a couple hours and you will have a thicker gluing area (thicker wall).

Then you may want to reinforce is some more with some CA around the joint then sprinkle baby powder or baking soda on it. Then sand.

This isnt guarenteed to last forever and be amazingly strong, but it works better than just CA.

The other alternative is brass and solder. This is really strong, and works well. Dont worry about it being to small for 1/24. If you use the correct tube, and good bender to keep the wall from collapsing it works. I've soldered rollcages for 1/43 without to many problems. It helps to pre bend all the pieces then mock them up in a clay base so you can solder them together.
