My engine will arrive next week, so I started some of the tasks associated with it. I needed to drill the locations for the cabin heat, throttle, mixture and carb heat. It was another set of tasks better completed with the subpanel out of the aircraft. The holes don't look round in the photo, but they are round. It is very time consuming to drill thin stainless steel and I did not get them to final size.
Edit: I finished the holes the next morning and then took the second photo.
