#9380, "Scale equivalents" In response to Reply # 4
indirectly, the Rigging Reference section can help you. If you look at the Scale Sizes table (posted here for convenience), it will give you the answers you need. Diameter is diameter, whether it's a pipe or a wire. Look at the right column (144) and find the actual size as was used on the ship. Follow it over to the second column (actual diameter) which will tell you what size rod you'll need.

Just experimenting with soldering various gauges of wire to make my own railings without having to buy any. I prefer to try and scratchbuild parts before giving into the temptation of just purchasing some. If I can't achieve the result I'm looking for, then I'll buy PE ones.
