The transmission tower is now complete and was done pretty well to plan. Again keeping things accurate with hole centers and the like is key to getting a good build. I was able to weld it all myself but getting it done at a fab shop would be no problem. It has been tried in the duct and the next job is the support wings and deflector plates. After a long wait I finally got my fan from Wingfan. It was good to mount it in the duct and see it spin with minimal clearance.
