So I'm finally getting started on the delta. I actually haven't had the plans long but a new baby has been my top priority for the last couple of weeks. Now that I've been able to sleep a little I decided to get a little work done. At first updates are probably going to be a little sporadic. After a while I hope things will be more consistent. Anyway, I've gathered up some of the materials I need to get started. All the sheet metal in the plane is .025 aluminum. Either 2024 or 6061, you have a choice. I'm using 2024. Spar caps are aluminum angle and there are random 4130 plate fittings throughout the plane. The plans have you start with the main spar. It's located about 2/3 chord of the wing just behind the pilot. It's made up of 1/8 inch angle spar caps and .025 spar web with .025 stiffeners. I only had about two and a half hours but I got a lot done. One of the Spherical bearings for the wing fold. Spar web stiffeners being made. Spar web cut with some pilot holes drilled. Center section main spar and cap. Yes they're curved. That's it for today hopefully more to come soon.
