The back of the boat was doing the old way -first cutting out the fine windows with a X-Acto knife before cutting out all the different parts (step 8/9).

 To do the bending of the roof, I “softened” the balsa part with the back of the knife by crushing the wood according to the supposed places where the planks would have been (step 8/10 & 8/11).

The details of the boat were first done by making an interior out of balsa 

then gluing it in place. (step 9/13). I proceeded to glue some small planks falling from the inside of the boat near the place where it broke. I added some of my last Grant Line plastic nails to add a bit of detail near those half falling planks (step 9/14) .

While I was working, I came to meet a Mechanical Genius thanks to the forums, who explained me in 5 minutes what I was struggling to understand since a good month. Most particularly I learned about asbestos being shaped as a rope and then fixed on the boilers with some kind of plaster –the whole being tighten on the boat’s hull with some very light bricks.

So I encircled the boiler with some model ship rigging rope and coated it with plaster (step 10/16). 

When the plaster was set, I ripped it out with a cutter so that it could look a bit scruffy, (step 10/17) I then glued back some of the plaster scraps to create a broken appearance. Finally I added some photoetch screws from an old Royal Models set as well as a front device which was adapted from a truck model’s engine which was lying in my “never to be finished” box.
I ended up by putting some plating above the “asbestos”. (step 10/15)
The bricks were simply done by gluing some evergreen strips to some plastic base, then pouring some plaster in them, waiting for it to set, and then cutting out some bricks.. (step 11/8)
