Falke T-61A Cliff Charlesworth Plans.**
This is the subject. It formed part of the South Australian Scouts Association Air Division.
This is my research sheet and Cliff's book.
Here is my new steel build table (Zincalume on 16 mm MDF).
And my magnetic building devices.
I found that when I unpacked it, the two Ribs 1 had been inadvertently left out. Cliff (Evans), tried to post me replacements but they fell victim to the COVID lurgy and disappeared into the ether. So I made two more from copying the others. Good practice. Thanks for trying, Cliff.
To get my head around the different angles of the wings, I tried a new strategy. I assembled fuselage frames 3,4 and 5 and installed the Rib sisters to those frames.

This gave me a jig to set up my wing spars.
More to follow . . .

Re: Falke T-61A Cliff Charlesworth Plans.
Here the two spars are being built.
And now the Graupner boxes are being epoxied in place.
Now I can build each wing around its spar and hopefully they will sit correctly.
Fingers crossed . . .

Re: Falke T-61A Cliff Charlesworth Plans.
OK On we go . . .
I will live to regret glueing those rib sisters in place, but . . .
When I checked Rib 1 with the plan, it was 5 mm too long. Remember their sisters?
So, I fixed the spar and the trailing edge on the plan and ignored the overhang.
I laminated some 3 mm balsa and set about adding the front sections of the ribs.
I made a device for sitting each rib on the table and measuring where to cut 9 mm off its nose.
It all worked out well.

Still more . . .
For a bit of a diversion, I installed the first of the wing joiner anchors.
Then I found that the balsa wing tip rib was very flimsy and easily damaged (how did I find this out?),
So I cut sisters out of 3 mm ply and added them.

Re: Falke T-61A Cliff Charlesworth Plans.
We're in the home stretch . . .
Keeping the spar and trailing edge firmly locked on to the plan, I then cut the ribs and glued them in place.
. . . and continued to assemble the other woody bits to the device.
You can see that I've remembered the crank. The washout has also been incorporated on the tip end.
Also the wing joiner anchor and the anti-rotation pin are now in place.
Tomorrow, the remaining woody bits go on the top and the whole catastrophe will be turned over and wooded.
Then, it's on to the aileron.
Woo Hoo!

Re: Falke T-61A Cliff Charlesworth Plans.
I have to deal with another diversion.
Remember that I made a jig out of fuselage frames 3,4 and 5?
Well, I've discovered that frame 4 is 4 mm narrower than it should be.
No biggie - I made a doubler out of 3 mm balsa and glued it on to the sister.
Then I used my 1.1 metre sanding bar to fair it in.
I'll do the other side later.
Cheers

Re: Falke T-61A Cliff Charlesworth Plans.
I think that I've got the wing worked out . . .
I might leave it there and get the left one to this stage before I move forward (also while I can still remember what I did).

That's coming along nicely Max. There is no need to forget your progress, just use your photos from this build thread.
