Hi Gaetan, I have wondered about building at your 1:24 scale, since I highly admire your work. But I would have no room in the house for the final project!
 
I was just given a booklet, entitled "Building a Model of the Flying Cloud, by James Tate, 1929. It has a lot of interesting information, and also images of how modelers apparently used to dress, with tie and waistcoat. At least the waistcoat keeps the tie from wrapping around your lathe!
 
I am proceeding with finishing the wales. Pretty straightforward after lots of practice so far on this little project. Here are a few unusual items of note:
 
In the third photo, I am showing a strake that still had too much springback after clamping to the hull overnight, I avoided forcing the piece into place by faying a small spacer onto the inner face to match the curve of the hull, and after it was attached, I faired the outer face to match the rest.
 
The first photo shows a jeweler's clamp I bought many, many years ago, and never used. But I have acquired a case of tendonitis, which makes it painful to hold small pieces for sanding. This clamp eases the pain. Should have used this years ago.
 
The final photos show progress, including a closeup of the hooked joints.

I picked up a cold on the plane back from our trip, which slowed me down the last week. But now better!
 
I initially tried building a Plaster of Paris sleeve around my moulds, to stabilize them and pull the two halves together securely. But I had trouble pulling them tight with tape before pouring the plaster; for some reason, this time, the tape just would not secure tightly to the rubber. And then I used old plaster, which was so lumpy and needed breaking up that it began to harden before I could pour it into the boxes. I had to throw all of that away.
 
Reading the Micro Mark instructions again (when in doubt, I keep telling myself, read the instructions), it suggested pressing the moulds halves between two pieces of wood. I initially tried that using clamps, but this distorted the mould and I cast an oval section gun.
 

 
So then I tried holding them together with rubber bands (per the instructions), and this worked well.

Here is the first cast:
 

Once I cut off the gun head with a jeweler's saw, I clamped it in the lathe, using a chuck on the protruding end of the muzzle to center it, and then clamping it in a four jaw chuck using a split ring of wood.
 

 
Then I could drill for the bore, and face the end.


 And the result:


 
Needs a little filing to clean up the trunnions, but the process seems to work.
