After a whole week of celebrating family birthdays, I had a chance to get back to fixing this problem. Step one was to cut the bracket down some more while also determining what additional material needs to be added.
Once the bracket was trimmed to fit and the cardboard bits were made, more of the 1/8″ bar stock was cut up and welded to the right side of the bracket. This was one large bit that went to the outside followed by a small corner that was welded to the inside so that the rubber bits of the mount are completely covered.
The left side is a lot more complicated because of the angle. I added a little bit of bar stock and then ground another bit down at an angle to support it. I need to get at least one more bit ground down and installed, but unfortunately I ran in to one small snag: Ran out of welding wire!
After hitting up Lowe’s tomorrow morning, I should be able to get this wrapped up pretty quickly.
