    Plasma cutting jig

    Thought I would post up a pic of a little jig I made up for plasma cutting bird mouth notches in square tube.

    Here is another view.

    Just some simple jigs to make my life easier.
    I also use the back side for cutting angles that my saw can't make.

    Re: Plasma cutting jig

    Ok most of my pics did not come out, if I get time I will take some more this weekend. Here are a couple.
    First let us say I need a 60 degree notch on 2" square. I take out my handy dandy speed square and scribe a line at 60 degrees.

    For the sake of argument I will be welding to another 2" square. So my notch needs to be 1-7/8" deep because I want the tube to land on the radius.Then I know my drag cup is 1/4" away from the cut line, so I scribe that off.

    Now all I have to do is drag my cup along the jig.
