finish line is getting closer
Sure, Terri. It always looks like you'll never see the end, with all those little things to scratchbuild and paint. And suddenly it comes to rigging and at last, the end is now close.

Your Albies continue to be stunning examples of work in this scale!

Thanks. I'm completing the rigging on the red and white bird. I'll post pix when it's all done on both aircraft.

Here's the front part of the maintenance tent for the Jasta 18 diorama. The tubular structure has been covered with fabric, which then has received a coat of white glue. This has made the fabric and folds in it look heavier, and has hardened the whole thing when cured. Once painted and drybrushed, the fabric's weaving looks rather heavy. I guess I'd better use silk for 1/72 scale...


Rigging the birds: a buckle is made at the first end by having a wire pass through a hook in the wing, and both ends go through a micro-tube. Then you just have to push the tube towards the hook in the wing, put a drop of glue inside the tube and cut one end of the wire away.


Tension (another wire is shown here). The first buckle is done. Then you put a tube onto the free part of the wire before having it go through the hook at the other end. Next step is to have the tip go though the tube a second time, which is usually tricky. When it's done, the wire is tensed by holding it with pliers and pushing the tube towards the hook with it, while pulling the free end of the wire.


Usually the tension is OK but you may have to increase it a bit with a hot scalpel blade.

Aileron cables are simple "go-through" wires which pass through holes in the lower wings. I hold them in tension with adhesive tape then drop CA in the holes.


Rigging completed and painted steel color on Udet's machine.

Great work, I admire it all very much -- although I must say I am not quite convinced by the turnbuckles. I think at this scale they take attention away from your otherwise superb details. JMO.

Like Bo I think the turnbuckles are to thick. But very good work.

Thank you all. Yes the turnbuckles can only be too thick with this rigging method, since the wires have to go through twice, which is not the case on the real thing. Actual turnbuckles are not much larger in diameter than cables themselves.

I know what I could do: at the turnbuckle end, a very small tube (the turnbuckle) in which the cable would come at one end, and a ring at the other. The other end of a rigging wire doesn't have a turnbuckle but some kind of muff around a buckle made from the cable itself (usually they are located under the top wing, turnbuckles being at the other end over the lower wing (probably for accessibility). These muffs could still be made from tubes the way I do now, and this would allow for cable tension using the same method. A small sketch:


Now this requires finding or building those rings from metal wire, and to put the rings on the wing hooks before gluing them in place, while avoiding to put glue on them...'turnbuckles' would then have to be glued on ring tips, and cables insiede the turnbuckles. I'll have to try this on a platicard template.

What size is the rigging wire?

They are made from 0.16mm nylon thread. It's still a little too thick, I'm thinking about replacing them with 0.12 on the Jasta 18 aircraft. I've been trying to figure out the actual diameter of cables. I found no information on this but looking at close-ups, they seem to be made from multithread steel and I think they should be a little less than 1cm in diameter. At 1/72, 0.12mm should be fine.

I think the actual 1:72 scale diameter is around .002" which is .05mm. I use .005" which comes to 0.127mm and that looks fine. The actual size of the lines varied according to their use, from around .05mm scale to .13mm so you're in the right area. Someone posted a diagram of RAF wire thickness on BE2 and SE5 (I think) fairly recently so you can work out the correct scale thickness from that if you can find it.

Thanks for the info. I tried to figure out the wire diameter from closeups with mechanics around, and it looks like wires are around half the diameter of a finger.

The wires were definitely stranded. The drag wires were 1x38 (a core of 19 wires twisted in one direction, covered by an outer layer of 19 wires twisted in the opposite direction. The running wires were 17x2 -- 2 bundles of 17 wires twisted around each other. You can find all this info in the NASM Stropp book.

Unfortunately, they don't cite a diameter, but info from other sources gives a typical diameter of the flying wires at around 4mm.  In 1/72 scale that works out to ~.06mm.
