Hi Don,
I hope you are keeping safe in the winter storm we are hearing about. I have the tail feathers covered now (Stewart system) and steady progress on other bits. Have you made any progress since your last report?

Sorry, I am a little confused. The angle of incidence (according to the drawings) is set by positioning the main spar, temporarily fitting a wing rib and taking measurements from the horizontal datum.
3 degrees angle of incidence equates to a
2 1/2 inch difference between leading edge and trailing edge of the wing rib.
This will all be accomplished in the tent in the woods. I will drill the wing attachment fittings in the spar when the spars are out of the aeroplane to ensure they are drilled square. The 3 degrees angle of incidence - I can use the measurements on the drawing, I just might need so wood shims.
The fuselage has been varnished on the inside and Stewart’s sealant on the outside. I am covering with the Stewart system as I hope to do that this winter in my house. Next big job is to permanently fit the spars and get the angle of incidence right.
With spars and undercarriage, it doesn’t fit back in the workshop! Quick plan, erect a tent in the woods and see how it goes! Next major job is fitting the spars, making sure I get the correct angle of incidence. Trial fits so far show the slightest change makes a big change to the angle. No absolutely sure how I can get a consistent angle, take it apart, apply glue and get it back together again with the correct angle.
She has wheels! Maybe held on with clamps, some bolts are the wrong length and I know it’s the wrong stub wing rib but….. she has wheels! Not long now before I can sit in her and make silly aeroplane sounds!
Productive couple of days in the workshop. Undercarriage stop rings, axles and torque link brackets all done. Soon it will be welding time. Just need to make the torque links. The brackets for the legs are with the welder now. After the torque links I need to assemble the centre spar and then I will have an aeroplane on its wheels 😁
Just collected my legs from a local engineering firm. They have done a great job. Axles and torque links next and I will have a pair of undercarriage legs 😁
