Sorry for the lengthy delay between posts. I had three annual inspections to do, the Jenny needed some attention and had to fix a friend's Jungmeister cowl.
But this evening was rather productive. The majority of the first spider plate lightening hole reinforcement strips were welded in place.
The long pieces of angle aluminum are used to keep the spider plate flat. Since there is a lot of welding, the metal warps from the heat. These angles act as a flat jig. I weld in the open areas, move the angles, then weld the remaining spots. So far, it has kept the spider plate straight.
