Anyone do this often enough to share some tips?

I am going to build a roll-cage for my big little jeep.



That's a mock-up using aluminum.

I was told i need some type of silver stuff?? and some flux, which i already have. What's this silver stuff?

I found this at wal-fart. It's a MAPP torch, which i hear is better for brazing than propane cuz it heats up faster.


basically from what i was told, i make the cuts on the tubing, clean it up, add flux to the end to be brazed, apply heat till red, then add silver whatever. Sound right?

I'm a complete NOOB to this. I've always used JB weld on my little big rig but it fails over time so this should hold better.

You can also get the silver soder at computer stores. its basicly the same. Just do some practice runs and make sure it hold like you want. Hell if you wanted to you could use a fire to do it. (Dont recommend). Buy you got the idea. I braze copper. but should be same diff. Just heat it up and apply. cool with wet rag.

Silver solder....It is available at heating and A/C stores.....I think it is very expensive.
Ahh that's what it was. Thanks.


Yeah i'm gonna practice a bit before doing the actual tube. I wanna make sure this SOB is sturdy and strong cuz i roll this little rig quite often and it's not so light. You can guess what happened to the original plastic cage :)

Can't be bought, only built ;)

I spent about 400-500 on it. Built everything except the axles and electronics and body. It's basically a downsized 1:6 version of a long-armed TJ/JK.

you mean motorS ? There's two, one for each axle. 55t integy motors, dual 4000 mah batteries, 10 tooth pinions. thing can launch and crawl, best of both worlds.

It can flex more than what's shown in that picture above:



that's with my skinny little pizza cutter swampers.

Long arms:


I'm about to build another, but using a jeep gladiator truck body. it's bigger than this one.
