I placed one ring face down on the work bench.
I placed the sheetmetal over the ring
I placed the other ring on the top of the sheetmetal and lined all 3 pieces together then drilled holes through the angle iron and sheet metal to bolt the frame together on the circle (as a sandwich)
This sign will be 2 sided. I needed a way to hang the sign and roll it around while I was working on it. I found a rolling partition frame. I cut it in half and added two pieces of pipe to make it wide enough to handle the sign
Having solved that problem I sent the sign frames out to the powder coater. While I was waiting on the frame I hung and painted the sign with primer on both sides.
After the primer dried I sanded the entire sign with 400 grit paper.
The sign will have 4 different colors painted on it and the first color will be the white for the stop light. It will have 2 red rings painted on it along with yellow letters and a black background.
I started by figuring out how much area I needed in the first red ring and painted the white in that circle
