Has anyone ever used thin brass rods for roll bars??? How would i determine the right size …
also, if i were to braze two peices together, what kind of filler material would i use??? and where can i find it??

Hey Ron…just curious but any particular reason why you would like to use brass rods? It could be done…I myself have never scratch built anything…sorry I cant be more help.
One suggestion is to take a pair of calipers and check the diameter of a plastic piece in the same scale that came with a kit…that might give you a pretty good base size for what your brass tubing needs to be.
Good Luck! And let us know how its turning out!

Thanks chris
Ron, I’m sure you could use brass, but have you considered just using styrene? Get a bunch of evergreen rods and you should be able to build a pretty good representation. Added benefit is that you don’t have to braze. Just normal glue.
Maybe I’m missing something?

yea Murray, i build a few out of old sprue, then graduated to round styrene, i was just wondering if any used brass…
I saw a dragster once at a model show , and the whole chassis and roll cage was brass… the body panels and engine and stuf were plastic… really cool car…
i have made entire vehicles chassis out of brass. i made a frame for my silverado out of brass rectangular tubing. ive made fully caged tube frame prerunner trucks out of brass. top fuel cars, lowrider cars with hydraulics. its the best because when youre done with it you can drop it on the ground from 5 feet up, and if you did it right it wont break. i use a soldering iron (40 watt and above), and silver solder with a liquid flux. i encourage you all to try it.

check out some of my work there.
I have to agree with ‘thelocust’, brass is the best stuff fort that kind of job. Use callipers to find out the right size to use or go by visual if nothing included in the kit. The beauty of brass is that when it is bent it has no memory so it wont try to go back to its old shape like heated styrene will.
Solder and a flux is great and if there is a little too much it files away easy, you can use it as a filler too on any brass.
Imagination is the limit with this medium!
HEY,
I agree with the two posts above. I used the same method to build a roll cage for a race car.

I have also used brass and aluminimum for roll cages but generally in 43rd scale. Because there is no strength requirement I used superglue which also acted as a filler. All worked perfectly.
thanks for your help guys!!!
