I noticed that you guys braze your tube chassis together. but the question that I have is how hot do you have to get the the tube and brazing rod for it to braze properly? thanks.

glowing, the only way to know for sure is to heat it up and touch it with brazing rod if it melts you're good

would 2500 degrees do the trick?

Mapp gas gets to 2509 I think it was and it is what most people use, so yeah.

IMO, don't bother with one of those micro torches from tower. A simple bottle of MAPP run with a MAPP/PROPANE (plumbing) torch just works so much better.

and try not to over heat the tube it will turn the joints black i get the tube red hot and when the braze starts to melt o move the torch away abit to keep it from over heating have fun its not as hard as it looks

I found that getting the tubing med. hot then melting a little solder onto the joint then heat until that solder BB loses its surface tension and fills the joint. I hope that makes sense.
