Great work on a great subject Erick!
Apparently, we have been doing a lot the same stuff recently.
Me on a mold to vacform the hull of an 18th century French ship of the line over, but with the same techniques and materials.
But you are doing it better! The holes in the frames to get Magic Sculp to magic Sculp bonds is a great idea! I will do that too in the future. And the use of metal for a sharp bow is vey clever too!
For anyone who would like to have a go, this is a great solution for those waterline kits missing a lower hull! Or of course for scractchbuilding an entire hull. The techniques are actually quite simple to do, it just takes a bit of time. For good results, the frames need to be cut quite precisely which takes some time, and the sanding of the Magic Sculp, and then priming, sanding, priming again, sanding again, and so on... takes time too of course. But the results are worth it!
About 10 years ago, I have seen large quantities of Magic Sculpt being sold in an art supply shop in New York, so I guess it should be possible to locate it somewhere?
I have used it a lot for sculpting 1/35th scale figures, and also for armour models (zimmerit, weldlines, gap filling, ...). It is quite widely used by figure and armour modellers in Europe.
On ship models, I also like it a lot for filling gaps. For filling small gaps after gluing painted subassemblies together, I carefully stuff some Magic Sculp in the seam, remove the excess, and smooth it down with a small brush with a little water. No sanding needed, and the gap is nicely filled and only needs a bit of paint on the seam itself.
Looking forward to further updates Erick!
