Got the dragonfly home safe and mostly put back together. Now that it is home I’m going to split the domain into two one for the hummelbird and the other for the dragonfly
Well N41gk looked so good I’m buying it. Bringing it back on the 8th. Still going to continue working on the hummelbird, but need a 2 place as well now that I got hitched. Also I think it will increase the time I spend working on the hummelbird since I’ll be right by it.
Took another new job. I’m now the director of Okeechobee County airport. The build will continue however I’m taking a real good look at a very nice dragonfly a few pics are below.
center spar is drilled out. Still waiting on the frame. Ordered a nice drill guide that made quick work of the holes and ensured they are square.
still working on the center spar. Purchased some 5/32” riveting supplies. And got most of the rivet holes marked out.
the spar cap on the right is correct. The one on the left should be flush against the outer cap. I slipped with the router and tried to sand the gouge out, but it took to much material off.
spar web should be 4 1/32” not 4 5/16” due to the .1875” radius of the spar cap. The inner spar cap is easy to fit by just using a 3/16” roundover bit set .040 too shallow.
spent an hour on Sunday putting the notches in the spar caps. Just rough cut them. I will sand the to the correct dimensions this week.
Also saw a video posted online of my ribs being formed up. It’s a tremendous time saver for me.
ordered a cframe riveter/dimpler as well. Turns out it is back ordered with a two week lead time. This will put me into February to finish the spars, but at least everything else is ordered and I still have some parts I can form up.
Built the spar jig together tonight. It was simple enough, flat and straight as an arrow. Built as a t with a center stiffener glued up underneath that won’t interfere with the clamps.
