    Default Tip: When bending with flame, flame follows the bend.

    I wanted to make a motorcycle luggage carrier so went and bought me some nice cold rolled rod. I clamped some 1 3/4" pipe to bend around for a nice arc. Well, none of the 4 bends come out the same because of my method I suppose.

    I was heating where I was bending instead of behind the bend. Heating behind the bend allows the cooler part of the rod where the pressure is applied to lead the rod around the mandrel. I was staying ahead of the bend just a tad, that left the back of the bend too cool to form around the mandrel.

    Then, to end a perfect work shop session, I ran out of gas on the mig and didn't realize what was going on till I was done. Welds look like garbage, very porris and I lack confidence in them so I'll be spending some time on the grinder/file circuit.

    Life's a bitch and then you get reborn. If I don't come back as a 44D bra I want to come back as a Labrador Retriever.

    Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

    It is true, there is nothing free about freedom, don't be so quick to give it away.

    Welding gloves are not for welding, Common misconseption
    Welding gloves are for the stupid things you do precisely 5 seconds *after* welding and the peice has stoped glowing red, so it must be safe to pickup now.

    Reminds me of when I was learning to gas weld. Dropped the rod and didn't notice I was picking it up on the wrong end. Didn't know I was burning til I smelled it. Then it wouldn't shake loose. Lesson learned.

    Before you start, fold the last inch of one end over. Then you'll know that isn't the hot end.
