Nothing like a wet weekend (& end of the summer racing season) to free up some time. I sanded the keel down to an approximate shape, glued the outer stem on & gave it some initial shaping, & glued the keel on. More pictures later but this shows the way I'm ensuring the keel is plumb. It's a piece of clear acrylic sheet with a line square to the base scribed on to it, then fixed to the building base. Two light strips of timber with masking tape stay the keel, I'll check it in a few hours, & by that time the epoxy will be stiff but not beyond movement, should there be an issue.
 
The following steps will be slowly & carefully fairing these to each other. Then the infill piece for the propeller cutaway. It's possible some filling will be required where the keel meets the hull, but we'll see.
 
thanks for the interest

Thank you John / Gary.
 
It is time to start what I anticipate to be a long planking job.
 
I am starting at the bulwark. I plan to plank the hull with mahogany planks of .062" thickness by nominally .220" wide. The plank widths will obviously vary to conform with the hull shape as progress is made. The bulwark will be made from a nominally 1" wide by  .032" thick birch ply which will be clad with .032" mahogany planks as per the attached sketch.

The bitch ply cannot follow the line of the bulwark exactly without shaping so it is being put on to sit slightly above the line of the capping rail. It will be cut back to the capping rail shape later in the build.
 
I started by glueing bits of scrap wood to the frames. These position / support the plywood during gluing. Each one cut back to  conform with the shape the plywood strip wants to take.

At this stage I also did the final sanding of the hull.

Then followed the slow process of fitting the plywood strakes. They were glued in position with a ample layer of PVA wood glue.
The strakes were held in place with plenty of notice board pins and elastic bands while the glue dried.

The plywood sheet wasn't long enough to extend the full length of the hull and the stern needed separate strips.


I didn't get one to the frames right and this was revealed "too late" by the application of the bulwark strakes. I will need to correct this before I plank the bulwarks. Stupidly having noticed the mistake I the repeated it on the other side. There is no fool like an old fool.

Applying the bulwark strake to the stern was quite challenging due to the extreme curvature.

Before attaching the ply to the stern I slotted it with a series of horizontal cuts.

With a bit of fiddling this enabled it to wrap around the stern.

A bit of sanding produced an acceptable shape for subsequent planking.

That all for now folks!
 

I started the outer stem & keel piece, that goes from the deck at the bow around to the keel. I decided to glue laminate it in one piece, partly because - as with the glued planks replicating strip planking - this is more akin to the way the actual yacht was constructed, as a timber / epoxy composite construction.
 
I had some sheets of Sapele from something & even the 1.75mm (maybe 1/16th) thick wasn't happy doing the curve, with heating. I had some 2.5 thick strips of Huon Pine, & they were happy to do it, with a bit of heat from the hot air gun. I'd rather a harder timber, but oil based enamel paint is quite tough.
 
I came across some tiny fine brass nails that I had bought & didn't use on a model, & decided to try using them to ensure the laminating is a close fit to the hull shape. Partly because the timber needs a finished thickness of 5mm, & with 2 @ 2.5mm there wasn't much adjustment possible. Anyway, it looks to have worked well, & hopefully hasn't been glued to the hull... I left about 1mm of nail sticking out, so I can pull them out.
 
It worked nicely:

 
Except for 2 (where a little more oomf was need to hold the timber in), the nail heads are left projecting a little to aid removal:

 
Here's where you can see how well this worked - no gaps! Helped by the general pliability of Huon.

thanks

I've started on the keel. The shape is not complex, so it can be modelled pretty easily. For stability & strength I decided to make it from horizontal strips of timber, dowelled with brass. The timber is a nice straight-grained piece of Huon Pine. The keel is not a difficult shape: it fairs with the hull, but essentially it appears to be even from there down to the bottom of the keel.
 
This is the keel side on. The yellow bands will be done in strips of timber.

 
The strips, in plan:

 
The timber pieces cut to shape, plus the 1/8th brass rod:

 
Stacked & trimmed, & sitting on the hull. It doesn't look quite right, but it will. The hull has more sanding to get it down to the right size, I have left that to assist get the fairing with the keel right.

Lovely work with your wood bending, Mark!
 
John

That looks really nice, Mark. Those small brass nails were called panel pins in England, I believe. I have a stash of them that used to be my father's. 

Hi Steven,
 
I hope you don't mind my adding to the discussion, but I don't agree that this is an error - if the shrouds were on the leeward side then they won't have a lot of load on them. A helmsman could intentionally sail an angle to de-load a shroud so it can be worked on.

The planking is finished & I've spent a few hours sanding. This planking method (strip planking at scale) was visually messy, so it's very nice to see the hull lines start to become more visible. Although the nature of strip planks (being parallel sided), the planking lines throw the optics of the shape off a bit, as the line of the planks towards the keel don't bear much relation to the hull shape....the planking just follows the ones above with no tapering.
 
The stern photos show the excess hull near the transom - that planking needs to be cut away - as the hull has the sweep down from the upper deck to the height of the transom. Photo below shows that gently curved line of that transition.

 
I'll do a bit more sanding & then start on the keel & outer stem pieces. Also the infill piece that will turn the square cutaway at the stern into the curved propeller cutaway. 
 
They are a fat boat.....

The model has been progressing, but the planking is pretty slow, but it is getting there. The simpler nature of a 'strip plank' style hull does reduce the technical difficulties a lot, but balanced by the relatively narrow planks. And the previous planked model was using Huan Pine, which is very supple, this is Basswood / Limewood & it's much stiffer.
 
The lovely lines are appearing, although it's not so visible in the model yet - the scallops from the gunwale line around the cockpit hasn't been cut yet .... & it's probably normal anyway.
 

This one shows the technique: bulldog clip clamps to hold the planks to the moulds & rubber bands to assist pull the planks down to the previous plank. The gunwale scallop at the stern is marked approximately in pencil & will be cut after the model is fully planked & removed from the building frame.
 

 
I'm starting to use the heat gun to put some pre-twist into the planks.

The epoxy is messy, but all will be forgotten once the sanding starts, but for now another few weeks of a plank or two per day.

thanks

Thanks Roger. That's my opinion entirely. A lot of this is educated guesswork based on (extremely!) inadequate source material. Of course we can't be sure it's all correct, but a lot of the fun is in the investigation of source material and speculation as to how it could be done, given the pictorial evidence (often affected by artistic licence), the archaeological evidence (often frustratingly incomplete) and the practicalities of sailing a wooden vessel.
 
And if later evidence proves one of the guesses wrong, one still has the satisfaction of having done the best one could with the information that was available at the time.
 
So, on to current progress. Shrouds and halyards in place, but only the foremast shrouds have been finalised.

I really do need to clear my workdesk before I take photos!
 
I made new silkspan sails - I wasn't happy with the first iteration. This time I made them oversize and folded the edges over instead of gluing strips of silkspan to the edges. The cross was painted on with Tamiya acrylic paint. I needed two coats for the "face" side and one for the other side. Considerably happier with the second version.
And I've added the blocks to the yards - for the tacks at the lower ends and the vangs at the upper.

Druxey, if I might pick your brains - how did you attach the bolt ropes to your silkspan sails (they look particularly good)? And the robands?

I love that last shot, beautiful planking.
More use of Huon Pine, lovely stuff!

Nice to see her progressing, Mark.

I've started on the keel. The shape is not complex, so it can be modelled pretty easily. For stability & strength I decided to make it from horizontal strips of timber, dowelled with brass. The timber is a nice straight-grained piece of Huon Pine. The keel is not a difficult shape: it fairs with the hull, but essentially it appears to be even from there down to the bottom of the keel.
 
This is the keel side on. The yellow bands will be done in strips of timber.

The timber pieces cut to shape, plus the 1/8th brass rod:

 
Stacked & trimmed, & sitting on the hull. It doesn't look quite right, but it will. The hull has more sanding to get it down to the right size, I have left that to assist get the fairing with the keel right.
