These plans show S hooks for attaching the breaching lines to the bulwark eyebolts. What gauge wire would you suggest, and would wrapping the wire around assorted finishing nails give good results?
I typically use whatever solid copper wire I have lying around - I have so much leftover from my pinball days. For small eyes and the deadeye strops and chains I use wire from Cat5E cable. Just strip off the insulation and bend around pins or small nails. For larger ones, such as the breach lines, use a slightly larger wire. BE SURE the hook or line will fit in it - if not, use a bigger pin or nail. I mounted a bunch of eyes that took one hook just fine, but needed to get 2 hooks in there, and just couldn't do it. Had to replace them all. You could also use a pair of jewelers round pliers (I have 3 different ones with different tapers). I went with looping and seizing the breach lines, then securing them to the eye with a pin.
Would you solder the eyes shut?
Since the guns will be glued down, I wouldn't waste time soldering. There will be little to no tension to deform the eyes. Anything under tension, such as deadeye strops and links, I always solder.
I made tampions for the 24 pdrs using small toothpicks and painted them red. Two pics are on fotki.
Cool idea. Mine has the flashing cannons, so no tampions for me.
