I got back into it again after a couple of week wait for materials. Airport metals supplied me with a square foot of 1.5" 6061 instead of the bar I asked for. It was kind of a blessing in disguise, more cutting involved but it did make it easier to hold. I still have all of my fingers attached at the moment! But all four brackets have been made. I still have a few rivets to do on the right spar and bolt the last bracket on and then on with the left one.
