So that's the secret. I was wondering how you were going to get access to the internal workings! John -
That's a great green you've chosen for the hull. I'm sure your local Bunnings will be open and happy to take your money tomorrow! John

Going well, Popeye! When you see them all together like that it gives a better idea of the huge task of planking all three at once! John

Composite built?

What yachts do you have in mind? They would have been built from wood wouldn't they? John -
Crikey! Take care, Andy - that doesn't sound good at all. Are you likely to have your power back in time for Christmas? John
-
Great progress, Piet! What are the four large holes and the four rows of small holes at the forward end of the conning tower? John

Ollie, That's very neat deck planking - well done. Yes, you're better to have slightly longer rather than very short planks, and although some ships have the deck openings 'framed' by the deck, most ships have the deck 'underneath' as you suggest. John

Yet more very beautiful work, Alexandru! John

Actually, I think you'll find that bending slabs were used until relatively recently, and certainly in the construction of frames in steel ships. There was a bending slab still in situ in the frame shop at Cockatoo Island Dockyard in Sydney definitely in the early 1960's - although not then used. If I remember rightly, I was told that it had been in use at least up until the 2nd World War. H.J Pursey's 'Merchant Ship Construction', which was first published in 1942, showed a bending slab as the standard method of frame bending. I recall that Pursey was considered a little old fashioned in his outlook, however bending slabs were recent enough standard practice in 1942 to be included in his book, which was a standard text. The first illustration shows the frame bending slab still in place in the smithy's shop at Chatham Historic Dockyard in England The second illustration is the drawing of a bending slab from Pursey's 'Merchant Ship Construction.

According to the web site Maritime Connector, the Gypsum Integrity was built by Estaleiro Ilha of Rio Do Janeiro, Brazil. John

Nice to see that she passed the 'tank testing' stage. Onward and upward! John

You're making very good progress there, Freek! John

Just catching up, Ron - that's looking very nice indeed. John

That looks a nice model, Ken! Have you had her out sailing (er, paddling) yet? John -

This would be a very interesting project, but would presuppose a fine skill in miniature metal working, as building a metal frame at model scale would be a major undertaking - although having said that, I'm aware of a model tea clipper built at a scale of 1:48 entirely from tinplate salvaged from used food cans. Most composite ships were built with a single layer of planking and, given the skills to build the metal frame, the next problem (as has already been raised) would be securely fixing the planks. It may be possible to drive headed pins through from the inside of the hull or, failing that, then fixing the planks with epoxy and then drilling through both plank and frame to insert pins, bolts or rivets. If the challenges mentioned above can be satisfactorily resolved (and I'm sure that they can, given a little thought and experiment), then the next question would be why build a composite model at all. The amount of work involved in such a project - far more than would be required of a model such as Ed's 'Young America'- would only be really justified if a cutaway model was planned. I'll be interested to hear any further thoughts that you have on such a project. John -
Andy, I think I'd build the four sides of the boom separately and then make a simple jig to align them when they were joined up. Is that the way you're thinking? John
-
Ollie, The painting shows her with conventional painted dummy gunports. The scuppers would be metal (probably lead) lined holes drilled through the bulwarks. You could easily leaving them off without spoiling the model in any way. John

In the summer, Tom - sunrise here is at 5.40 at the moment! John -
