Uwe ladies nail files are good for removing char, and cheap.( The paper type, not the steel ones)

I will give it a try - thanks for the hint

I checked the joints of the second frame and it is better - not good, but better

on the top the second one


and a closer look


Yesterday I spent 2 hours for preparing the third frame - and I tried even more sanding away the char - the real problem here is the type of the joint with these flat scarf joints. You have to be very careful in sanding, only so much on every part, that they still fit together. A normal butt joint would be much easier to prepare.



To be honest, with 2 hours work per frame, I could also cut them scratched with my scroll saw -

Maybe the manufacturer should start to combine in their kits laser cut parts and also cnc-cut parts (for elements where laser char is a pain)

Hello Uwe,

the ZHL model looks good.
I wish you a lot of fun and success in the construction
of the cross-section.

Hi, Uwek!
Several years ago I've built this model. The kit was not very detailed, but the result looks not so bad)))

Very good model - so you put the level now very high for my built
We will see, how my section will look like at the end

Sure it will be better!!!
One advise meanwhile - try to avoid using the photoetched parts from the kit - make yours parts using wire etc

G'day koreets, that is a very nice model of the cross section you have built,

best regards John,

 

[Uwek]

Step by step...... the joints of the third frame are slightly better (the latest one on top) - It is acceptable for me now, so I will go forward with the same way

 

[Uwek]

I want to show you also some excerpts of the plans available and will asap compare them with the Boudriot planset of the HMS Bonhomme Richard

Here the drawings of the kit

For those who interested. One of the photos from Koreets (Roman) was an award: a diploma and silver medal for his section model presented in 2015 when he participated in the Russian Championship. Bravo!!
Uwe, sorry to higjack your thread.

Excellent looking model. Can you please advise what you used for the trenails?

Thanks

Uwe, sorry to higjack your thread.

No problem, I am happy, that there is some talks in this topic....
Because I realized the medal, I mentioned, that the necessary level for me is high now -
@Koreets ,
thanks for the tipp with the photoetched parts - I will see, what can be done

 

[Uwek]

Four frames finished and dry-fitted in the jig - upside down
Frame number five was today glued and is drying - all together the section has nine double frames





Sorry, but it in moment a little bit boring....... but in some days the framing will be finished

 

[Uwek]

Yesterday I showed some excerpts of the kit drawings, but I forgot to show the cross section of the model - not shown is the internal construction (add-on of the kit)



And in the following the excerpts of the Bonhomme Richard drawings from the Boudriot monographie, in which I marked the part of the section with red lines
Sorry, that the photos have a different scale / size.......







And the cross-section - It is obvious, that several details were changed or adopted - f.e. the hanging knees, thickness of the inner planking.
I will see, how much I will adjust the kit in order to get closer to the planset "version"........



Many Thanks for your interest ..... to be continued ......

Wait...I have noticed that one of the frames laser char wasn't cleaned. Did you change the game plan and will sand once all 9 frames assembled or?

Hi Jim,
I think, that I will sand them outside of the jig, minimum 90% of the char.
The first three I made it only on some parts, in order to check the joints...... Many thanks for your comment

Thanks, John!

For planks - the pear sticks, for wales - the black hornbeam sticks

Today I want to show you a small but important detail of this kit, which is the first time I saw this in section models.
If you look at the section models of other suppliers, like Victory or USS Constitution, I think the frames have over the length of the section everytime the same form.
But in reality, off course the hull form is following the lines of the ship, so every frame has a slightly different form.

Here the excerpts of the Boudriot drawings showing the lines of the Bonhomme Richard




Here you see once more, which frames and which section is part of the Section model


Unfortunately in the drawing set of the kit, there is only one cross section drawing, so we have to calculate by ourself the difference and mark it on the drawing in order to have guidance for the frame elements.

Here you can see the small difference of the width in the jig, with the frame 9 which has the smallest width


To make it more clear here the side of jig and the cross section drawing of frame 1, which is very close to the midship-section "M" (see Boudriot drawing)


and now we take a look at frame Nr 9


Here a short notice on the sketch copy
The width of the of R1 is appr. 18,6cm - R9 only 18,1 cm so 5mm less

For the frame Nr.6 with I made yesterday evening we hav appr. 18,3 cm which is marked with pencil lines -> The frame elements of frame Nr.6 have to fit this marks

you can see, that the elements are not following any more the cross section sketch

Visible also very much already at the floor timber, when you compare the form with the drawing




To be continued.......

Hi Uwe,
So if I understand correctly, is there a slight narrowing of the cross section towards the stern?
