Le Rochefort 1:36 build by Tony P

[Tony P]

Donnie. My lumber was cut for the Hahn method so it’s thin strips that I’ll cut the frame blanks from. I’d think it’ll take about the same amount of lumber regardless of framing method so you’d just order wider strips.
70 pcs 1”x24”x 7/32
34 pcs 1.5”x24”x 7.32

7/32 is almost dead on 5.30mm

Two days of work besides the wing transom (transoms). The first two were not really thick enough. It’s easy to thin them down too much while trying to get the form. Start very heavy and work down like I didn’t do.
I’m going to concentrate on the axial structure for now since I’m deep into it. Make sure every thing is a proper fit, mill the keelson and rising wood then I’ll put it aside all aside and start the frames Hahn style.

Thanks Tony. Novice question… I keep seeing reference to the “Hahn Method,” can you elaborate or point me to a reference about it?

Hi Tony, please recheck the assembly of your tailgate site, I think you need to rotate the crossbars 180 degrees.


Here is an example

 

[Tony P]

I see what you mean but no. the flat side is up. I'm not finished forming them either. I may end up making new ones later on.

Master model shipwright Harold M Hahn

the material in this article comes from the archives of Harold Hahn. Now you may wonder what archives? The story is after Harold's wife Nancy passed away the family decided to clean out the house and sell it. One problem they had was a life time collection of books, and research material Harold...

This is from Dave at The Lumberyard. In short its a method of building frame blanks and cutting the frames from them instead of having to cut every piece of frame individually. It also incorporates a hull building method in which the tops of the frames are extended by an exact amount allowing you to build the hull upside-down. I'm not doing that I'm just using the frame building method and building my hull in the normal fashion. Seems complex but it really isn't.

Thanks Tony. Dave’s treatise on Hahn’s method is great information. Since I’m currently reading Underhill’s books, I see some similarities between Hahn’s methods and Underhill’s In building the frames. Underhill liked building the hull in the traditional shipyard style if “from the keel up” but also constructed the frames in a similar manner to Hahn and used a support to keep the frames aligned. However Underhill placed the support Inside the frames at or near the waterline Instead of making a jig around the outside of the hull.
Really love learning all this new information and enjoying the support of all the expert shipwrights on SOS. Thanks!

Yes there’s a few ways to skin a cat. I’m “trying” this method. Success isn’t guaranteed. This is only my second POF the first being only the Blandford hull section.

Hello everyone, I asked again about caulking in the French forum. Here is Gerad's answer, I have translated it into English for you.

As I said, I'm not an expert and I'd rather ask again.

For the "water stopper pins" it is relatively new in France (late 18th century), but much earlier in use by the English.

As for the contact surface between the keel structural parts, they are systematically tarred and a felt cloth is placed between them before they are dowelled.

Hi Tobias, did I give the right news?

Thanks that’s great. Not caulking as we think of it but the same thing really. I do like the look of it so now I’ll proceed and add the paper.

 

[Tony P]

Milling progress today. Slow and steady. I have ended up making a few parts of the bow structure again as they just weren’t right.

Gerad made a mistake and corrected it, I have corrected it. He didn't mean the end of the 19th century but the 18th century, if not earlier. So we are in the time of Le Rochefort.
Yes Frank you are right, I am tilting my head . But only from the middle to the end of the 18th century, before that there was no such thing on French ships.

Hi Tony, very good progress. You are really fast, keep it up.

Thanks. Winter is here. I work everyday all day on it that’s why.

Hi Tony, what thickness did you end up using for the keel, stem and stern parts? I saw some discussion on whether 6.95mm or 6.75mm were correct… Also, are you also using beech for those components? Thanks again for leading this novice.

 

[Tony P]

The results of quite a few days work. Ill
Never take these keel assemblies for granted as “easy” again ! Perfect no but I think once I add the paper “caulking” it’ll look fine.

Using Beech yes since I have it left over from Blandford so I’m using beech for the entire keel, frames, deck beams etc. when I get inside I may change it up or wait till I get to furnishings and topside to change up the wood type a bit. It comes out to 6.55 nominally what I’m using. It’ll work. Yes 6.75 is the correct size.

Hello Toni if I may say so.

This little slope is not right, if you could show the plan briefly then I can better explain what I mean.
