It's time to drill the holes for the scuppers. I'm concerned with the planking splintering when the drill breaks through. Does anyone have a slick method of avoiding this?
 
Thanks, I'll try sneaking up on it. I want to make a jig so all the scuppers are at the same angle so I guess I will have to increase the hole size in the jig as I increase drill sizes. I was going to use a small rat tail file but the hole I want to drill is .089", quite a bit smaller than my smallest jewelers file.
 
Gluing through, lacquering or painting the exit side of wood block will also diminish it to splinter on bit exit.
 
I'll do that :)

While I'm here, are scuppers evenly space along the ship? I know there are 5 or 7 on each side for a Sloop of War but I don't know about where they go. Is it a no no to put one in the middle of a gun port for instance?
 
Thank you Uwe. On your ship and on the Swan series the wales are just below the main deck. On the Discovery the wales are 4 feet (1.22 meters) below the main deck. Do you think the scupper should still exit just above the wale? The red deck is the original that I am using.

If possible clamp or secure a piece of wood on the EXIT side of the hole. That will eliminate splintering completely. Works on bg holes asc ell as small holes. And where possible, use brad-point drills for your holes as they score the entry for clean drilling. Another trick for tiny holes is to first dimple the hole with an awl before drilling. And as always, try it on scrap if you're unsure of the results.

I do not think, that you have to bring down the scupper outlet above the wale, in an angle down (30 to 45°) it will be correct

See this drawing of a ship of line which has several levels of scuppers

Proposal for fitting scuppers to Ships of the Line
Scale: 1:8. Plan showing a part section illustrating the fitting of scuppers to the upper deck and lower deck for Ships of the Line, as proposed by Mr. Lang.


 
or this one

Canopus (1798); Armada (1810)
No scale. Plan showing a part section of the upper deck for Armada (1810), a 74-gun Third Rate, two-decker; and a part section of the deck (for both upper and lower) for Canopus (1798), a captured French Third Rate, now fitted as a 80-gun Third Rate, two-decker. Both sections are illustrating the fitting of scuppers.

 
Thank you again Uwe. Those drawings were just what I was looking for. I wish I could read the text on the first one. I tried converting it to black and white but it just gets blurry.
I've never had much luck searching the RMG. I'll have to try harder.
 
Cant say for sure on number or exact placement, but not below gun port, if on an armed ship, but normally located between frames as needed.

On bigger ships like Uwek shows are more complicated, but on smaller crafts, they may just be level with deck cut thru side of hull almost level with deck.

It's looking to me like they are evenly spaced but I would think that there would be more scuppers in the waist where it's the wettest. I don't really see any need for them under the quarterdeck(like in the captains and officers quarters) but sometimes they don't do things the way I think.:)
 
keskin uçlu bir matkap kullanın ve yavaşça delin
use a drill with a sharp tread and drill it slowly. Google translate worked great on this one :)

What I ended up doing was drilling with a small new drill from both sides. Once I wiggled it around so I could get a thin wire through I could see the angle it had to be. Then I used a sharp drill the right size and enlarged the hole. Any splinters are inside the bulwarks and can't be seen.

Sonunda yaptığım şey, her iki taraftan da küçük yeni bir matkapla sondaj yapmaktı. Bir kez kıpırdattığımda, ince bir tel geçirebilseydim, olması gereken açıyı görebiliyordum. Sonra doğru boyutta keskin bir matkap kullandım ve deliği büyüttüm. Herhangi bir kıymık siperlerin içindedir ve görülemez.

How did that translation work?

Take a look at this topic.


a lot of the NMM drawings are also available at a special area on wikipedia, with often very high resolution.
Maybe you find there the drawings
