Step 9Light Bracket Arms and Chain Mounts
The Light Bracket Arms will stick out from the uprights and provide a place to weld the chain mounts.
1. Cut two pieces of angle iron 18-1/2" long. Clamp the two pieces together. Using a square, make a mark 1-1/4" from one end, and a second 9" from the first. This will provide spacing for the lights.
2. Using a pair of linesman pliers, cut off the threaded portion of the screw eyes.
3. Using a small welding magnet, position the screw eye on the mark, center and align it and tack weld it in place. Repeat this for the other three screw eyes/chain mounts.
4. Unclamp (careful it's hot!) and offset the chain mounts to provide access all around each base. Clamp them back together for ease of handling.
5. To complete the welding, make a second tack opposite the first tack. For the third side of the mount, strike an arc on the angle and run a short bead past the base of the mount. The arc should just brush against the mount to weld it fast. Repeat to weld the fourth side of the mount. Do not try to run a bead in a circle around the base of the mount; the mount will overheat and melt off.
6. Position the arm on the upright using a large welding magnet. Put the two flat legs of the angle together.
7. Tack weld the arm to the upright in the back.
8. Check for square, adjust if necessary and weld into place.
9. Take a picture of the huge beetle on your saw horses. BTW that is 1/2" plywood.
10. Using a pair of needle nose pliers and the cheesy chain that came with the light fixtures, spread open the end link and hook it over a chain mount.
11. Using the needle nose pliers, squeeze close the link so the chain is captive on the chain mount.
