Nige, hey no, not vacuform. first i would have to build a machine and I am quite bad at doing that, and then what I truly need is all the individual planks of the boats to be seen at the place where the hull will be destroyed.
So What i will do is actually PLANKING ABOVE the plaster master -and then adding all the details on the internal side.
It shouldn't be a problem except that i read that there was 2 coats of planking on Elcos, and really, as I don't have any reference pics for this, i will leave it at one..
On the other hand the book I mentioned earlier has got fantastic pics of PT Boats while in construction which shows all the inner planking!
Thanks Rudi

You know it's all in *focusing* in a diorama job when you start it

No, I didn't put it on my own blog for programming reasons, as I didn't find a convenient way to show the both that are running right now -that one and the Masséna.
And then Jaws will be a small diorama, more a scenette with one fig actually. But there will be water etc, all my usual antics.
To be honest the work I display right now is already one week old so I will definitely show a 1/35 fig near it -as soon as I can that is! For the moment the boat is less than 10 cms high, and the part I will be using will be sort of 7cm high and 4 cm long.
Matthew! yes It could have been the Nautilus! Somebody pointed that to me already that when upturned; an Elco's hull looked like the Nautilus.. hmmh, food for thought
Thank you Kosprueone as always -- But you know I perfectly know the SBS is not that glamour these days, but i promise it will soon be more colourful!
My wife thinks that peanut oil is really too bad for health, so that one got straight to my diorama shed.
So i do a Magic Sculp lump that I take in sandwich between 2 sheets of oiled (with the peanut oil, that is) glass.

Then I waited for one good hour -if you prefer, the mastic must be cutable and bendable but not too sensible to finger pressing/prints.

I used a steel plaque to create triangular shape that I use as a keel..

planking is for tomorrow!
