how about a Oklahoma,AR,MO,KS,TX,+IA GTG thread?

Good Morning friends. Stay warm and dry today. Tell 'em like it is Cobey.

Morning warmed up to 36 over night still dry but chance of rain.

sawnami tell me a little more about this aluminum brazing.Do you use a propane torch or acetylene.Were do you get your rod? You really did a good job on it.

I'm learning more as I go. They say you can use a propane torch but I think that would only work with thin aluminum. I use an acetylene torch. The area to braze has to be just above 700°. I'm having best results with HTS 2000. It's important to remember that the flame just heats the area and not the rod.

Quite correct. I have brazed thin metal with oxy/propane and it is rated for aluminum. Oxy/acetylene = faster and less frustration. That last part he said can't be stressed enough. The heated work area will "pull" the rod into it and form a strong bond.

How do you tell when its at the correct temperature? I have one I need to repair. Just don't want to wind up with a puddle of aluminum.

In school we were told to soot it black then set torch. As soon as black leaves it hot enough.

So, when you say soot it black, do you just crank up the acetylene to put a black coating on it?

I shoot it with the infrared temp gun. You can also smoke it with an acetylene-rich flame then heat it until the layer of smoke disappears as hoskvarna said. You've got a 500° degree range between the melting point of the rod and the melting point of the aluminum.
Brazing is being used more in auto body repair now with the special alloy structural steels to keep the heat from welding from altering the strength of the material. MIG brazing is becoming the preferred method over welding.

Getting beat up here trying to play Yahtzee. I never have been to good at games...

I loved that game. Used to play it all the time when we were kids. Just played UNO with my 2 oldest nieces, mom, and little brother a couple nights ago. I hadn't played it in a long time either.
