While the daytime temperature range is just below my riding threshold, I can feel that Spring is approaching. So, I made significant progress this past weekend. Previously, I had figured out how to attach the rack to handle the loading. I had basically used 1/2" square tube to use the same fastener for the seat and oriented the tubing to use the turn signals as support. So, the 'base' was in place and I needed to fabricate the rack itself and then weld everything together.
This is what I originally envisioned which is pretty much what I ended up fabricating.
