Now I'm a little confused with the bow planking

[Don Case]

When I line out the hull one of the sections comes to a point before it reaches the stem. All the tutorials I've read say that planks must lay naturally. This won't work in this case so I must be misunderstanding something. Is it that the planks should lay naturally "after" they are spiled?

 

[Gennaro]

That's my understanding - they should "lay naturally" after they are spiled. Take a look at David Antscherl's outstanding tutorial on hull planking http://www.admiraltymodels.com/Planking_primer.pdf Merry Christmas!

Hi Don "must lay naturally" is a rule of thumb for very thin planks otherwise the edges will cup. Usually refers to second layer planking on kit models. On full sized ships the planking was bent in both directions to eliminate what you have shown. Move the ends of the lower two lines or spiling lines down a little to even out the spaces on the stem. You will have to fit joggle planks and the planks bent edge ways somewhat.
Looking good.

i agree with Allan

the 2 belts of planking under the wales should not come together to a point and from what i can see the bottom belt is a bit to high on the stem.

someone did a lining off the hull somewhere on the forum but heck if i can find it

 

[Dave Stevens (Lumberyard)]

lining off should look more like this with enough space at the bow in each belt.

 

[Dave Stevens (Lumberyard)]

here are another examples i found on the forum note the space of the belts at the bow.

as far as planks laying natural that is the planks are cut and shaped to conform naturally to the shape of the hull so they do not buckle or have to be bent edgewise

It's a very bluff bow, it's very close to a semi circle at the forecastle. Where I seem to be having trouble is the three points where the lines hit the stem. I can move them around a fair amount and still have it look reasonable. I'll go though my method and see if you can see any errors.
I lined it out into four equal sections. Determined that there are five planks per section with 1/4" planks. At the stem for the first section under the wale I assumed that I would need full taper so 5 1/8" makes the first section 5/8" at the stem. That's where I am in this picture. Nothing glued. Darn clamp is in the way but maybe you can see how the planks are laying.



Now I get confused. The next section is very close to the first at (I think) about 5/8" but as I go further down the stem to the third and fourth section the planks are hitting the stem at a decreasing angle so I need to leave more room. So I guess it's the curve of the stem that's messing me up. I'm thinking as I'm writing so my thoughts may wander. Should I be marking the points on the stem equidistant (vertically) from the wale to the keel/rabbet? Anyway thanks for the help. Merry Christmas

Dave do you have a link to this build? It looks like I could learn something there. Sure wish I knew how you guys find this stuff.

Thanks, I notice that they don't seem to worry about the width of the planks where they meet the stem unless that's just the drawing. My initial impression with the Discovery is that I won't need any stealer/drop planks if I'm really careful. that just adds to the difficulty.

 

[Walterone]

they don't seem to worry about the width of the planks where they meet the stem

There must be at least 2/3 of the initial width.

 

[Don Case]

There must be at least 2/3 of the initial width.

Everything I've read says 1/2. I wonder if Steele has anything to say about that. Rats, puzzled again

 

[Walterone]

In theory even 1/3 is enough, but the more the better.

Hi So I'm going to go ahead and start a build log of the Winchelsea, It will based off Syren's designs with a few modifications of my own. My main reason for building her is because she was once captained by Pellew and I intend in the future to build another of his ships, a 1:48...
