I spent some time fitting the outside formers for the skylight. I got the right one tacked in place when I realized I needed to put in the nutplates first, before I welded it in. Thank goodness I rememberd as it will be MUCH easier to do it this way! I marked the location of the nutplates and cut the tacks loose. I fit the left side as well, but as with the other side I need to put in the nutplates. I'll need to order some 3/8ths inch diameter sets for my squeezer so it can get inside the channel to set the rivets.
