Re: Aluminum Brazing
I used a Bernzomatic high output swirl torch with Mapp. From what I've seen propane would work just as good. The rod melts at 730F, you don't have to get it really hot and you need to keep "scratching" the rod while heating to even see if it's hot enough as you can't see any change in the stock. As with all brazing you heat the parts and the part melts the rod. The "scratching" and brushing are to break through the oxide.
I was impressed to say the least, I was not expecting my first joint to come out as nice and easy as I saw on the videos. I was really impressed after beating the crap out of the part showed no failure of the joint.
The only thing in my garage with 4 wheels is the lawnmower
