Take each relief carving one at a time. Looking at the whole tafferel load at once is rather daunting!

Thanks Druxey, you bet.  I am not made of the right stuff to attempt doing it in one piece.

Keep at it Gunga Din, you'll get there.  I have the same issue with the booms, so many small parts to add but I am almost there :)

Oh boy is this update overdue.  Berwick has been in limbo while we make some big decisions.  And now ... I have packed up Berwick in anticipation of a house move soon.

Status to date: all frames cut and fettled to fit the spine on the building board, ...

After the picture above was made some of the intermediate spacers have been fitted (all will be explained when the shipyard is reopened).

Also, preparations for decorating the stern were started by making a work-holder under an illuminated magnifier.

Since no work has actually been carried out, that too will be explained when the wait is over. 

So now, time to put Berwick safely in a rock-solid box!

Secured, padded and treble-checked.  After giving her one last gentle stroke the box was screwed down tightly. Don't know how long this will be her home but hopefully it shouldn't be too many months.

I may be some time ...

hope the move goes smoothly and your back to building soon

Great to see another post Bruce and good luck for a hassle-free move.  Look forward to seeing your build on the workbench again.

 

cheers

To test, mill a piece of wood to the desired thickness according to your best guess. Ten small sections of this wood are glued together face-to-face and lightly clamped in a vice. When cured, the combined thickness is compared to the scale plans of the framing. It is either right or wrong, no half measures.

After four attempts, it turns out that the correct thickness for my purposes is 2.2mm (.087”). I was able to achieve this +/- .1mm consistently so I felt confident but took one extra step to keep things within spec: all blanks were graded and the thick, the thin and the spot-ons were sorted.

So, if I were to paraphrase the goal of this testing effort, it would be that because of the scale of the model one would need to figure out the thickness that the glue adds. Would that accurately reflect the intention?

Good question.

Answer: Pretty much.

Yes, it is the glued-up dimension that matters so the glue is a part of the assembly being measured.  

Please bear in mind that the method being used requires the hull components to be glued and prised apart and re-glued together more than once so, spoiler alert, at various points in the future it will be necessary to re-test the assembed frames for size. It shouldn't be a problem but the potential for the hull length to 'stretch' as the pieces absorb glue before reassembly is real.  Hopefully my cunning plan will deal with this if needed.

Thanks. That’s one of the things that’s kind of interesting about wooden ship models. They are very much dynamic, almost living things. Very much different than plastic styrene kits.

 

Do you have a rough idea on the thickness of the glue? Maybe the added thickness after N frames yeah?

Hello Alan,

So far there has been no noticeable added thickness, presumably because the glue soaks in rather than sitting on the surface.

The process requires multiple assembly/disassembly steps and I will be watching for build-up of Seccotine on the frame faces which would affect the final dimensions.

I agree, there is a dynamic element in a wooden scratchbuild project that takes on a life of it's own. The whole Berwick project is on hold due to an upcoming house-move but, despite stowing the components and screwing down the lids of the boxes I built for the move, it is still on my mind.

Can you give a hint as to why you needed to sort your planks into these three piles?  Apologies if the explanations already been posted and I missed it.

Hello Alan,

The thickness variation is slight but the effects are cumulative.  The first purpose of sorting was to ensure that both left and right hand sides of a pair were exactly the same thickness as any discrepancies would cause problems with the steps shown in post #33 above.

Also, although I didn't explain it in earlier text, I ensured that no visual variations appeared in adjacent frames.  We are only talking about .2 to .4 mm variations but a quick dry run established that even these small differences were sometimes visible when next to each other.

Plus, I'm fussy about the little stuff.
