In my yoof I studied Naval Architecture and General Ship Construction, helped make a brand new 27’ Whaler out of a wreck and built a model clinker built Launch. That said I haven’t recognised 90% of the parts of this model. You’re a star Mark, honest!

Jerry - Hello mate  :-)   We are looking forward to you getting down our way this year  :-))


Now here's a confession - I didn't know what 95% of these parts were either until I started this build  {-)   Every day is a school day for me at the moment but I am enjoying it!!

Ok I've got a bit more done  :-)


Firstly I sent a few more hours fairing the inside of the hull as it going to be planked out quite soon.  Next I took the measurements for the deck clamp and transferred them on the model.  I did this by modifying my height gauge which actually worked very well





Then as I'm sure that most of us have done at some point was to use a baton to join up the dots to get a solid line








Then the same on the other side to get a nice uniform line around the inside of the hull











So now the fun begins  %%   At this scale the deck clamp (the timber that all of the deck beams sit on) is 3.4mm x 9mm and I need to bend it around the bow.  The bow is far too fragile at this stage to take any heavy clamping so I need to preform it.  It is also a very harsh bend due to the Dutch style hawse timbers but I'll give it a go.





The other issue I need to solve is that the clamp is made up of 4 individual pieces which are joined using hooked scarph joints - another first for me but I do like a challenge.


Cheers Mark

When you’re preforming the deck clamps, soak them in ammonia window cleaner in a length of hose with the end pugged. Leave 24 hours then form them and let them dry. That’s how I did the coaming on “Wear”.

Thanks Jerry I've never used ammonia  - when you say leave them for 24hours is that with them clamped in place when wet - or before I try the bend?

Soak for 24hours then clamp in position. Do both at the same time bit by bit from same end of hull so equal stress on each side of hull. You’ll find them very flexible. Leave clamped for 24 hours. When dry you can glue them in final position. It’s easier than steaming. The best wood to use is ash.

Piece of plastic drainpipe (underground type) blocked one end and a cap for tother, filled with ammonia/water mix, ideal soaking tank for sheet Balsa. They come out with a rubber like flexibility, form and clamp and allow to dry. Don't forget to add the eye of toad and tongue of newt. Seriously though, used this for years on toy aeroplane construction and results are eyeopening, especially with ammonia BUT do it outdoors. Mixture of choice was the outlet fluid from Diazo printers, ex D/O.

What's the current brand of choice? The one I used to use is now "ammonia free"

If it says it’s got ammonia in use that.

I bought ammonia solution from our local Boots the chemist, it's lasted for years.

Thanks for the tips regarding the ammonia  :-))   I bought some 33% stuff off Ebay and then diluted it down with water.  I think I have enough ammonia to last a lifetime of wood bending now  %%


I made up the formers to the correct bend








The soaked wood bent around without any issues at all - This is 9mm x 3.4mm strips











The only issue at the moment is that the wood has changed colour quite a bit.  It may return to its natural colour when dry so I'll see what its like next weekend.  If its still looking green I'll try and bend some using heat but hopefully it will be okay.

Are these test pieces, as they are vertical, any bends due to the vertical nature of the piece would need shaping for a rake in the top to the bottom - don't know if you understand what I am on about,


formed as shown but as they go round the bend to follow the bend vertically the ends would lift to form the shape or are these pieces naturally flat and those below will 'twist to conform to the correct shape ?


oh and is the green skin deep of through the whole of the wood

Yes these are test pieces as the formers are not yet there final shape. You are spot on about the rake or camber being required as otherwise they will not sit flat against the hawed timbers. The plan is to use these pieces to work out the rake and then apply it to the formers.


Unfortunately this morning the wood was still a green colour so I would say that it’s permanently stained. So the next set will be given the water and heat treatment and I’ll see how I get on with that.

Hi All


Some more done  :-)


Firstly the wood stayed a green colour so I had to try and bend the wood just using water and heat.  I also changed the former to incorporate the the frames camber and I also increased the curve due to spring back.  I'm glad to say that its turned out ok but I still need to bend the starboard side.








I have also made the third breast hook which it different to the other four hooks as the profile on this one is not flat.  Once I had worked out the machining sequence it was quite easy to make.  The deck clamps have a long notch cut into them which the breast hook sits in.  Here's a few pictures which explain it better than my words.























Cheers Mark  :-))

Thanks Ray and Phil  :-))   I’m really looking forward to getting into some of the more detailed work but still loads of structural work left first.

Hi All


Well what a challenge these 3 parts have been  <*<   I made and discarded 4 sets of deck clamps before settling on the ones that I used.  The combination of difficult bends which had to be recessed to accommodate the deck clamp all aligned correctly inside the hull..............wow!!!


Anyway I'm there now and quite happy with the result even though I did get a little damage doing it.  The port deck clamp went in ok but the starboard side cracked and I didn't notice until the next day when the clamps were removed. 


It was one of those times when I thought well its in exactly the correct position even if its not that pretty!  So I opened up the crack and placed a sliver of wood in as a repair.


The pair of deck clamps that I eventually used





The recess for the breast hook





My first ever hooked scarf joint





Pictures of all 3 parts finally glued in  :-))














I've now got to make the 6 remaining parts of the deck clamp which are all joined with hooked scarf joints.  Its a challenge but its a good one  :-))


Mark  :-)

Thanks Brian  :-))   Have a look on Ancres website which is French. Would you believe that Le Rochefort is pretty much a basic beginners scratch build compared to what monograph’s you can get from them. It’s well worth a visit.

A basic beginners build ?  that makes me feel quite inadequate, I'm going for a sit down in a dark room for a sulk  :(( :(( {-)

 %% %%  Have a look at the plans for a 3 deck ship of the line. It really shows what can be done - just the under deck construction must take months. There are some amazing ships to build if you have the time  O0

Hi All


At last the deck clamp is finished  %%


I've become quite adept now at making hooked scarf joints











The parts all fitted inside the hull.  It would be so much easier just to make this as one piece instead of the four that it is - but what a lovely detail that I think needs to be done.








A couple of close ups - the bolts are 0.5mm carbon rod that goes all the way through to the frames








I'm now waiting for some wood to arrive so that I can start the inside planking.  The planking inside this ship is fully caulked and completely seals the hold due to its cargo of gunpowder.  I've not done this before so plenty of challenges ahead.


In the mean time here's a set of 14 planking clamps that I've made in readiness for the job





Cheers Mark
