Fantastic progress Hubert. Glad that the production of the reinforced struts went well.
Your experiences with 3D printing will be kind of a guideline for us non enlightened. In surfing we call the first person in current dummy :D

Cheers Rob

Thank you guys, you are too kind with me ☺️ (only Kevin seems to have had an honest assessment :rofl:)

You know you have beautiful eye(let)s, honey ?

Well some more progress today. I had prepared some time ago eyelets for the rigging, using shamelessly the late Les Delatorre's technique for mass production.

So I had a bunch of those :

They are made with 0.3 mm copper wire stolen from an old electric motor. I have a lifetime (and more) of copper wire supply with this one.

Now was time to insert them in all the anchor points for the rigging (and a proof that the holes had been drilled ;)  ):

When all the holes were duly fitted with some eyelets, I was left with this, of my original 56 ones :) . And I did not loose one in the process :piliot:! (But there is one - the short one - which fell off the fin but i could find easily, thanks to a T-word - this one is for Martin ;) - bench. Which is why you can count 5 in the tray, when, of course, the number used is even, 52)

If you wonder, the hook is the tool used to wind the eyelet, after it is inserted in a pin vise. Des Delatore's website is still up and his tips for WWI rigging are invaluable.

By the way, the long double eyelets will have a fairing built around their base, to reflect the Potez 25's original system.

Once all eyelets were inserted, I fixed them in place with a drop of CA, using my very high-tech glue dispenser :

It is a sewing needle, of which I ground the tip to keep the  eye open, and inserted in a pin vise. When it becomes clogged by CA, a dip in acteone will clean it, and in the last resort, three seconds in the flame of a lighter and the CA is gone.

One last bit of work this afternoon. When printing the new parts, I managed to get very thin walls, for instance for the carburetor intakes. The walls were 0.25 mm thick. Unfortunately, this also means they are fragile, and, of course, one of the carburetor intakes did not like all the handling :brickwall::

I decided to replace it with a part made in brass sheet: even if it was knocked, it would bend rather than break and that would be easily fixable.

My soldering skills still suck, but I managed to solder a replacement inlet in the proper cone shape :

And in position :

You may have noticed that the left inlet is bigger than the right one. The Lorraine engine was a W12, and the left and upper cylinder banks were fed by a single carburetor, bigger than the one for the right bank of cylinders. hence the larger inlet. Btw, this is another detail that Lukgraph missed, with two identical inlets supplied.

Et voilà !
