Fokker did not use solder on his ferrules.
Using NACA Technical Report #3 on bracing wire & weaved cables, I have an idea of how strong I can count on these wires to be.
https://ntrs.nasa.gov/archive/nasa/c...9930091028.pdf
Fokker only used this system because he did not trust his unskilled welders, and wanted to back them up with the bracing wire. Otherwise, being the first all metal tube fuselage, bracing wire could have been left off.
Besides the wire, I had to use the old style weaving method for various cables on the plane.




Very nice! The rudder cable ends on my Waco EGC-8 are wrapped and soldered since they can be seen but all the other cables are nico pressed since nobody can see them but me. Good on you for tuck and splice the cables but I don't have the talent nor enough blood in my body to do it. True craftsmanship.

Jeff,

The leading edges are the first that I have seen that have a "V" cut out of the plywood that points forward from the spar. All I have seen are solid all the way around the nose from spar to the spar. But, I've never seen a Fokker DVII wing uncovered. In fact, I don't think I've ever seen a Fokker DVII in person! Really a neat plane.

I understand now what you mean,
The plywood fades below the rib capstrip and the fabric follows the capstrip smoothly.
A pitts would seal this all up, adding strength to hold any twist in the wing ... but it isn't needed in this wing.

The leading edge looks like this. notice how the fabric fades away from that plywood.


From above ....

and again without fabric.
These openings also make installing or adjusting any bolts that go through the front spar possible.
I can get my hand in there pretty easily.

Finally Jeff! Glad to see you make it over here! I'm a WW1 nut at heart and hopefully will do a Dr1 if I can ever get my Starduster Too done. I even have a meeting with VR3 about doing a tube kit for the Sands Dr1 at OSH this year. Trying to get a lot of the parts in line so it won't take so long when I'm ready.
Your build is truly museum worthy. Fantastic work! Can't wait to see more and more pics etc.
I still have the prop hub when you're ready.
Have you looking into some sort of clear UV protector? Surely there is something. That's way to much money and work not to protect somehow?

The Irish Linen lasts up a lot better than A-grade cotton. Kept in a hangar with the skylights blocked out it will last as long as most of the posters on this forumů..

Hi All,
I got the engine reassembled & timed the magnetos.


my son and I pulled the fuselage out of the basement and moved it into the garage to install the engine.

here is the engine installed.

here it is with the engine cowlings on.

You are about running out of excuses to finally assemble that thing. The engine is nice.

Looking good. Never seen as Ellison on a Ranger...is this the first? I also notice you have the two intake ports connected for a manifold pressure gauge? Never seen that done either. (Not that it's wrong). My MP is picked up on the center manifold piece. (The part the carb bolts to)

That Ellison TBI came with the engine when I got it.
It ran like that for about 40 hours before it sat for 14 years.
The two fittings in the intake manifolds are to prime the engine.
