I am looking at building a trailer useing aluminum and was looking through here to see what is the best to use on aluminum but didn't really see anything that seemed to be holding together. What is the best thing to use? I have a wire welder but I don't have any gas for it will the self shielded wire work or is there a better option?

i use flux coated 3/32" brazing rods from any hardware store like home depot, home hardware, lowes etc.. found a plastic tube with three lengths and 36inches long for 7 bucks at home depot..they work awesome. i cut them into 1ft lengths so its easier to move around.

A long time ago when I was in high school I had a welding class and learned how to braze. I was pretty good at then and for a little while after that. I just tried to braze the other day and all I could acomplish was melting a bunch of metal and making a mess. I guess I am going to have to do some omore practicing!!

Hey guys, learning a ton.
Here is my first 90 deg joint that came out how I wanted it."thumbsup"
The second pic is of a 3mm nut on the end. I haven't figured out how to keep it square on the end of the brake line and able to be brazed at the same time. Any ideas?

Yeah, I had some issues with that. I ended up just using a plate and drilling and tapping later.

Rockridge,
You should have been present for the French lesson that I gave after I did the same exact thing you warned against. :evil: It wasn't pretty...

I'm pretty sure for whatever reason it has "expired". Do a quick search for vids on google, you'll find plenty to watch.

A tip for brazing, or specifically not brazing on something is you can use soap stone (used for marking on some metals). Draw a line on where you dont want the puddle to flow and it will stop it, in moderation.
Also if your mig welding anything with threads or a surface you want to keep smooth you can take your torch if you have acetylene, light it. don't turn on the oxygen and cover the part with the black soot and it will prevent light spatter from sticking to the surface and will wipe away when finished. This would work with stick welding too but I doubt your stick welding RC cars together (i hope)
Also to the guy trying to do stainless, I don't know if you can and if its turning black that is too hot and it is loosing its stainless properties at that point. Its not a common practice and I can't seem to recall anyway to do it that I'm sure of. I think I remember having to set the torch to either a carbonizing or oxidizing flame setting but just can't find the answer.

I put this up in another thread, and was asked to add it here.

I've been trying to get this nailed down, but I can't quite do it. I'm using brake line, sanded to remove the coating. I have silver solder and standard flux. Is there a silver solder/brazing specific flux, or will regular soldering flux work? I started with propane, then picked up Map-pro. I might need a new torch head, because sometimes the flame goes out unexpectedly. Though I've found if I hold the bottle tipped slightly down it's a stronger flame. I can get the solder to stick in small parts of the joint, but I can't get a complete bond. The result is I can break the tubing apart after it cools by hand. The joints are very weak. What am I doing wrong?
