1/20/24 I finally got my 18 gauge sheet metal and the bottom flange for the seat riser. Unfortunately, the sheet metal shop ordered galvanized instead of plate steel. I took it anyway because I wanted to complete reinstalling the seat riser. Yes, I know the dangers of welding galvanized steel. I original plan was going to butt weld the flange to the riser but decided to plug weld from the back side minimizing the fumes from the galvanized steel. I also ground the coating off where the plug weld was going to be. While welding, I opened my garage doors in 13° temperatures to ventilate the fumes. Overall, I am very happy with the results. Another issue, is the temperatures have been way to cold to apply any primer. It’s supposed to warm up to the low forty’s next week so I may have a chance to get my garage a bit warmer so I can prime all the exposed metal.
