A joint that is not clean and tight will end up having an ugly, weak weld. Let’s make a jig, an invaluable tool that holds two chunks of metal at right angles while allowing ample room to weld tacks in the corner.
Steps
Step #1: Lay out and clamp.
Next
- Lay out the angle iron on the inside of the square and measure 1” from the inside corner. Clamp the cross bar behind it at about the 3” point.
- Don’t use your granddaddy’s favorite square. Anything could happen!
- When welded, the diagonal cross bar will hold the angle iron at 90 degrees until California falls in the ocean.
