Working With Metal Continued

 

The top of the adapter is where I'll weld the arm to.
 

 

 

Here I'm cutting the angle iron to three feet long.
 

 

 

Next I used one of my bar clamps (that I use for woodworking) to hold the adapter against the angle iron so I could tack weld them together (arrows).
 

 

 

Here is the tack weld. I removed the bar clamp and then fully welded the arm to the adapter.
 

 

 

Then I cut a two foot piece and welded it to the longer piece. The button will be at the end of this two foot piece. And I also added a diagonal piece for strength.
 

 

 

I left a small gap between the diagonal piece so wires could pass through for the button. I did this on both sides.
 

 

 

Here is the button that my son-in-law gave me. The button is 2" in diameter and can light up if you wire it that way.
 

 

 

I'm going to make a bracket that will hold this button and then weld it to the arm. Note the arrow pointing to a raised area on the mounting surface of the button. I'll need to make a cutout to clear this on my bracket.
 

 

 

This bracket is about 2" square and will be mostly covered by the button.
 

 

 

I chose this spot to weld the bracket to because it gives the button the most clearance for the nut and wires.
