The plans and the construction manual arrived. I spent some time, 2 hours, just looking at the scope of the project before begining to tackle hands on work. I then spent 3 Hours on CAD design for the wing rib parts and jig. I spent 30 minutes to create the firewall computer drawing. A total of 1.5 hours -was spent on the block 2 metal parts CAD work. Since, I have a laser-cutter I set up to make many these parts very acurately and quickly. Those I can not cut will be sent to a service center with a more powerful laser.
