Good Morning Randy!
 
A bit late answering you too...
 
 
I wouldn´t go that way, even if you fair the frames before erect them yes or yes you´ll have to make more fairing work inside and outside of the hull. It´s my opinion of course. One thing I can tell you, by adding the keelson the strength you give to the hull is enormous.
 
Other thing that worked for me was to glue the aft and fore frames first, faired them and then glue the square frames. It´s much more easy to sand this two parts than if you have all of them in place.
 
Beautiful pics anyway, nice and clean! Best wishes Randall!
 
 
Daniel.

Well, I decided to take my chances and go with basswood for the frames.  I think it'll be alright, but time will tell.  The main reason is funds and availability.  I already got 2 of the 9 frames put together and getting ready to cut out the third.  I'll sand all the frames fair once they are all put together and installed on the keel.  It's a slow process since all I have is a jewelers saw to cut the pieces out with.
 

Hi everyone, so I'm a day late in posting photos, but here they are.  I'm still working on the board mounting system.  I should have some pics of that method sometime this weekend.
 








 

Okay, to show everybody the design details for deploying the mines, I'll add a few copies of drawings for yuns to get a good idea.
 
There are still a few questions I have about the actual design inside the ballast tank but for our purpose that's not an issue.
 
There is a lot of detail on the drawing Remco posted with his comment and I could decipher most of the language, which helped my to get a real good understanding of the design and the mine securing mechanism.
 
Okay, here are a few pics.
 

This is the body plan of the original Navy project for a mine laying sub they designated as the O17.  This was in 1934.  That's 80 years ago - - - and the year I was born!
 

This is the revised body plan by Engineer G. de Rooy.  This is what was used to build the K XIX, later renamed to O19.
 

This is the same copy Remco showed.  It's rather small and I had this drawing blown up and printed out by a local printshop.  There is a lot of detail on these pics that makes it very clear how it was done.  You can also see that it was from the original Navy plan but on the bottom on the left drawing you can see the redesign by de Rooy.  I have enlarged that portion and is shown below. 
 

This is another drawing showing the bottom of the ballast tank / mine bun area having a hole in it.  It also shows the original Navy project before de Rooy's changes were made.  
 
Admittedly I have not done any research on how mines were deployed and activated but my guess is that  the mine assembly, i.e. the mines with the sinker were dropped as a unit and upon hitting the seafloor the sinker would release the mine which then rises up tethered to a cable.  Doing it as Mark mentioned would not work for submerged deployment of the mines, it would be like instant death to the sub. 
 
Cheers,

Wow, I'm overwhelmed with the responses and all those who visited and "liked" my progress, thank you all.
 
@ Joe JPZ65: Thank you very much for your kind words, and Yes, I like to believe that my dad would be rather pleased with my efforts and hopefully not much criticism   I also like to see the finished product    But it's coming closer.
 
@ John (Lad) :  Thanks for visiting John.  Yes, sometimes a little paint may seem that giant steps have been taken but still a lot of works is ahead.
 
@ Michael:  Thanks also for dropping in, and yes, the red and green really make her rather unique.  I also like it.
 
@ Boris: Hello Boris and thank you as well for your kind words and I can't wait for yours!
 
@ Mark:  Thank you Mark for your compliments!  Well, I have to admit of being a dummy or domkop for not going to my drawings.  They are right behind me and as soon as I saw Remco's post I slapped my forehead   And also Gino's comment, it makes absolute common sense that the mines had to be deployed from the bottom.  More about this most likely in a follow-up post with pics.
 
@ Remco: Thank you my friend in adding that drawing.  Like I mentioned to Mark, I'm so forgetful lately and feel stupid in not remembering that I have these drawings you got for me from the Navy Archive.  I looked at them closely and yes, there are openings in bottom part of the ballast tank / mine bun area.  I also see doors at the bottom and the mine securing mechanism.  btw, that drawing was the original Navy version dated 1934 for the O17.  This was later modified by ir G. de Rooy as the final design and build as such.  Looking at the two versions de Rooy's design makes a lot of sense.
 
@ Daniel: Thank you for visiting and thanks for your kind words.  Well, that blue bucket was handy for taking pictures, I really have to find something more suitable   I used RustOleum spray cans, the old rattle cans    The area to be painted es just too much for my little airbrush and too small for my high capacity industrial spray guns.  No, I am not considering the actual build dock or slipway.  Reason is two-fold, 1. when the boat was launched she was not completed that was done later.  So, my model will be as she was when completed and on her way to the DEI (Dutch East Indies) when my father served on her.  2. A moot point but yes, too much work.  
Yes, she's coming closer to completion but there is a lot more work to be done yet.  Hatches,  torpedo loading gantries, the dingy and rigging and not to forget, the deck-launch torpedo assembly.
 
@ Popeye:  I hope you didn't hurt yourself with dropping your jaw to the floor   Thank you very much for your compliments!
 
@ Gino:  Thank you my friend for your accolades, appreciate it very much.   Yes, as I mentioned above, I was being dumb in not remembering those drawings Remco send me.  I also remembered that I was not planning on making the bottom drop-down doors.  That would have been really the cat's meow but also a lot more work.  
The original plan was to just build the O19 too look as close as possible from the outside by using the model drawings for the O21 and guessing the shape of the mine bun area.  Then Remco sweet talked the archive folks in getting inside a making copies of the lines drawings.  Then it just evolved from there.  He also got me some more drawings as I went along to get more details.  However, the basic hull was already build when I decided to add more of the details, which actually made the build more difficult and challenging.  If I had to do it over again I certainly would do things different with the express purpose of a lot of detail  that i am now not doing.   
As it is right now I have already far exceeded my original goal and am very satisfied with the result.
 
The lettering I am looking for are the load draft numbers, Remco made me the bow numbers too. 
 
Cheers to all,

Piet,
 
I impressed! The green really makes the boat 'pop'. It looks great!
 
To solve some mysteries...
 
The mines were loaded from the top, and launched from the bottom. Of course this happened while submerged. One of the crew members once said that he was terrified during a mine laying operation; in shallow waters with all the noise they were making while dropping mines.

 
Then, for the lettering...Check these photos:

The boat at its commissioning in den Helder. 
 

Surfacing in 1943 (Loch Long) You can see that even during the war the O19 lettering on the bow was still present!
 
Hope that helps,
 
Groetjes,
 
Gino

I was missing that old good blue plastic container...
 
Do you use spray cans or an airbrush? There is a shot that actually look like two subs in one, one on the top of the other. The lines are simply beautiful Piet.
 
I have saved the pic of Rotterdam, the one of your father on the deck... Have you considered to make a dockyard like that? I know, I know... More work, more work but with your skills I see it possible...
 
Almost done Piet, almost done... closer closer...
 
Best wishes!
 
 
Daniel.

Amazing Albert...
 
How many ships are you building at the same time?? There is at least three of them on your shelve!!!
 
Beautiful.
 
 
daniel.

I think it safe to say that many of us have missed the build log and are REALLY looking forward to seeing that amazing detail again - I almost got over the addiction and here you go teasing us again
 
cheers
 
Pat

Great progress Piet!
 
One of the drawings shows a lot of mechanics in the mine tube but I cannot make out whether it was released from the bottom or mechanically hoisted upwards in the tube. But the drawing suggest lids at the bottom too.
 

 
Remco

First of all, thanks to everyone for visiting and clicking on "like."
 
Today I cemented the torpedo loading dolly tracks to the starboard side of the deck going aft.  I used N scale flex track for the rails.  I think I mentioned in a previous post some time ago that the actual tracks were U channels where the wheels for the dolly fitted inside the U.  This was to prevent the dolly from tipping when hoisting the torpedoes from the dock.  In any case, these'll have to do - - - I won't be making the dolly anyhow - - - he says with a straight face
 
With the tracks now cemented on I can paint the deck grey in preparation for the wooden deck slats.  But before I can do that I needed to paint the starboard side green above waterline 7, the demarkation between red and green.
 
Sooooh, I took the boat outside and masked her off and wiped the white primer with some enamel thinner and then proceeded with the painting.  I first sprayed  few light coats on till tacky and then a fuller coat.  Let this get tacky and repeated that three times.  I then removed all the masking and brought the boat back inside and on the build dock to let the paint cure where no dirt could settle on the still soft paint.  
This was all done before lunch.
 
After lunch I rotated the build dock so i could drill the gezillion holes in the port side mine bun lids.  That in itself was a tedious and exacting job but it seems to look okay.  Now I have to repaint that area, which is no problem, just masking out at the skin plate seams and the wale.  That'll we do tomorrow.
 
Okay, I have made a few shots from different angles, yuns are probably sick and tiered seeing the same profile pics   
 

Starboard side masked, ready for paint.
 

All masking is removed showing the freshly painted starboard side.
 

I took the model to the front of the garage and set het on a plastic container for a few shots.  I'm thinking of a painting of her and am looking for ideas.
 

 

 

 

Here I am approaching in my P-38 for a buzz job   
 

As the lookout may see the bow plowing through the seas 
 
Cheers,

Hello Mark and thanks for dropping by and your kind words.  Hmmm, dropping mines, very good question.  Not having the drawings of the hull and ballast tanks I'm going out on a limb and guess that they were deployed from the bottom.  At least that's what my common sense engineering mind would think.  When we consider possible rough seas when on the surface that would make it a rather hairy operation.  It would also allow the mines being deployed while submerged.
I would say, no compressed air but just good old gravity.
On the other hand there are tracks on the starboard side for the torpedo loading dolly and that thing had a hoist arrangement on it.  But that leaves the question, what about the port side, no rails there?  
 
My short answer is, I really don't know for sure right now.  Perhaps Gino can shed some light on this.
 
Hoi Sjors, good to hear from you!  Well, not only mines but 5 inch shells, 40 mm AA shells and 21 inch torpedoes.  She was a lady that could and did bite.  No "cottoning" with her my friend    You can have your cotton cannon balls, rather dainty, eh what?    
 
Hi Popeye, thanks for dropping in and your kind words.  Yeah, I always wonder about some of the builds that never show a boo boo and a pile of discards.  The ultimate discard was with Mark Taylor, took a lot of guts.  If I can only concentrate and pay attention more often then my rate of boo boos will go down     Glad no one can hear me when I screw up, it's then "oh shoot" and I can't spell worth a hoot either     Talking about paint - - - check the next post 
 
Cheers,

Hello everyone and thanks for visiting.
 
Today was more of  a prep day to paint the starboard side but I needed first to drill the small holes in each lid.  I laid out the pattern on each lid and then pricked dimples in the right places with a sharp awl.  This made the drilling easier, not slipping all over the place.  
I also made a "fixture" of sorts to do the port side, I forgot that before I painted that side.  Domkop me 
 
I guess it'll be ready for the green tomorrow if the weather is warm enough.  I also put another coat of red on the bottom andI need to wait for the primer coat and the red to cure before I can mask and paint it.
 
As soon as the green paint is cured I can mask the sides so I can paint the deck but first I need to cement the torp loading dolly tracks to the aft deck though.
 
Here is a shot as it currently is with the new lid in primer.
 

 
Cheers,

Thanks bob, on the new lid.  I think too, it's a keeper.
I'll use the ones Remco made, they are superb and hoping that I don't screw it up. 
 
Here are two pics with part of the draft hummers.  You can see how hard it is to read because of the resolution.   I think there is a software program that fills in the missing pixles, not sure though.
 

 

My father is on the boat during the launch.
 
Cheers,

One more update
 
the first canons in place for testing position
it´s not easy to hold the ropes in position
 
  
 
 
 
Have fun
 
 

Yes, everything whitout rope are made from bone
 
And here are the mistakes during the work *allmostasecondbeforefinish*
 
 

here a small update
 
the Blocks are now finished to takle on the Canons
 

 
 
The side takel had to be made once again because the hook and grummet were too long.
Everything carefully re-open (2 hooks broken) and a new strops. But this time in the correct length
 

The cannon rigging  part one

The Breech

The breeching tackle serves to prevent the gun after firing, to fly through over the deck. ( Secular terms )

Scientists would / express something else incomprehensible : mass times the muzzle velocity , including the air temperature and humidity = measured at the shoe size of the gunner .......... etc. etc. results in ::: A breeching takle is required !

The breeching tackle by the guns of the Royal Caroline was probably spliced ​​behind the breech around the trowel .

To install this required a device :

A bracket in the final length of the breeching takle and the cannon was to build.
Simultaneously, a device for positioning of the gun was used .

 

The gun barrel is inserted into the bore of the holder ; Breeching rope to the standoffs attached and the splice been marked on the dew.

 

The splice is a rope / thread in the strength of strands (3  or more strands laid together forming a rope)
The splice is then threaded into a needle and pricked with the needle through the rope placed around the trowel and out on the other side through the cable .
On the way back you wrap the splice depending on the length of 3 - 4 times to the existing Part.  At the end back through the rope out it goes back in the same way ( wrapped ) .
Thereby the end is not too thick, splice the stand again to the left or right through the dew, leave a small piece and cut .
Now there is a fixed eye spliced ​​to the existing breechrope .
In this way, all eyes and cringels (on sail)  can be made. This not only looks good, it is by working technically still correct !

   
 
 



Now the work is still dressed and ready is the breechrope on the trowel


   


The next step is to attach the eyebolt on breechrope .

Therefor the gun is fixed to the mounting board and fastened to the retaining ring bolt in the assembly position .

     
 


So it looks when the ring bolt is fastened . The glue ( white glue ) is wrapped with serving .




On the ship the ring bolts will installed for the guntackle and tackle .

   
 
The second part - guntackle and takle fastening follow soon .


Until then, good luck with your projects

All hands on deck.............................he i said aaaalllllll haaaaands
 
After I make the many hooks, eyes and blocks (for the guns) have already spots before the eyes, was a small relaxation törn due for the eyes
 
Therefore, I once make another figure from the bulwark ornament.

The images come in the series of steps.
 
After the figure was transferred to paper and glued to the bone support, it was sawn on the contours.
 
And now have fun with the pictures:
 
 

 

 

 

 

 

 

 

 

 
 
Have fun

Thanks, druxey and Gary,  This construction is all the more amazing when you see how big these pieces are in relation to my captain.
 
For those looking very closely, you will see that the center timber is temporarily coming down onto the top of the sternpost. It will be cut away for the rudder hole, but I wanted to anchor its lower end while shaping everything.
 
Mark

Hi everyone,
 
I have started construction on the stern. The first images show constructing the transom at the quarterdeck into which the vertical timbers will dovetail. When I taped it in place in the third image, I realized that there were too many parts in motion, and I would need a jig to keep it all aligned.
 
So the next images show a jig at the location of the stern lights. The most important thing to keep straight in this construction is the equal spacing of the stern lights.  The jig represents the windows themselves, with the correct round up and round aft, and the locations of the vertical timbers. I then cut slots for the timbers into which I could locate them while shaping them. I did not have to work very hard to create the right bevel; I just filed the aft faces flush to the jig.
 
You will also see that I initially mounted the jig on a right angle fixture over a slab of granite. This allowed me to use a flat, parallel surface from which I could construct the radiating lines for the vertical timbers with a drafting triangle. Once I found the correct angle on one side, I could flip the triangle and draw exactly the same angle on the opposite side. That kept everything perfectly symmetrical from the center. I initially tried to do this while the jig was located on this ship itself, and there were too many things in the way.
 
Still lots to do...
 
Mark

here first time experience Begins with metal plating for hull
The hull wooden surface is sanded smooth and fixed with quick dying transperant liquid filler, which drys off quickly leaving a real smooth and shiny surface on which the self-adhesive Aluminium foil sticks like hell. No Problem with roll-embossing the foil plates from the rear plate side, because the rivit immitations are roolled-in before the protection foil on the plate rearside is removed, giving free the glue film.

Mark, there is a book by Charles Desmond, Wooden Shipbuilding.  It is quite inexpensive.  The pictures of wooden shipbuilding are truly amazing.  Most of the photos were taken in the late 19th/early 20th centuries when the practices were still similar to earlier periods.  Highly recommended.
 
Allan, you may not have noticed, but I dropped the method of erecting the frames as a paired unit in favor of setting them individually.  Much simpler and way faster - especially when using the planksheer ribband.  The problem with setting as a unit is getting glue into the joint and clamping of the feet to the sides.  Both have to be aligned together and to allow clamping the assembly must be flexible.  I found individual setting to be a much better process.  More to come on that in the next post.
