Selecting Fittings Sizes for Your Scale Model
In considering fittings for your ship model, you would use the scale ratio to select the appropriate size. If you’re building an 18th century ship model of 1/64 scale and want to buy the right size barrels for the model, you would start by determining the size of real-life barrels as they would have been used on the real-life ship, and you might have to exercise your Google skills. One excellent source for estimates of real-world sizes is modelshipworld.com. In the case of barrels, you’ll quickly find there was no standard size for 18th century barrels, and unless you can find a photo of your real-life ship or specific reference, you’ll have to make a best estimate.
In the case of water casks, I think they might have been 34” to 36” tall. If you accept my estimate, a water cask for your 1/64 scale ship model should be 36” divided by 64, or .56” tall which is slightly over 14mm. As I write this, Model Expo offers a walnut barrel 14mm tall by 12mm wide, which would be about right. To select any other fitting by size, the formula is simply real-world-object-size divided by model scale!
So why don’t we just label our 14mm x 12mm walnut barrel as 1/64 scale? For that matter, why not label all ship fittings with the appropriate scale? The reason is that the scale derives from the size of your specific real-life object. If you wanted a 1/64 scale “hogshead” or “butt” for example (which were barrel sizes typically larger than water casks), you might want a 17mm tall or larger walnut barrel fitting. But the same 17mm walnut barrel might make a fine water cask for a 1/50 scale model. So it all depends!
