|Profile. They need about 15-16mm depth|
Before I cut the cabin sides, I wanted practice using the circle cutter. For the first time ever, I took the top off my drill press and adjusted the speed. I couldn't find the table that shows belts to RPM, so I just used the slowest setting. It still vibrated and wanted to shake off the bench, but I successfully cut two rings from scrap plywood.

I cut the outside circle first, then cut the inside circle. Be sure to pay attention to which way the cutter is oriented or you'll get sloped sides and have to sand. (And be sure to flip the piece over when halfway through to do the other side.)
Against instructions, I used a battery drill on low speed to cut the cabin side circles. I didn't adjust the cutter at all so that the circles matched the rings.
This was a royal pain. The cutter would get hung up occasionally and was terribly vibraty. After much fussing, it did finally cut through.
Lesson learned: subassembly first.
