Dr PR Posted April 24 Share #91 Posted April 24 You were talking about making sails and looking for a material of approximate scale thickness. I am currently working on sails for my 1:48 schooner and I am using the thinnest #00 silkspan. It is 0.0015 inch (0.0381 mm) thick. Here are some scale thicknesses for comparison. Scale thickness inch mm 1:1 0.0015 0.0381 1:24 0.036 0.9142 1:48 0.072 0.3048 1:64 0.096 2.4384 1:72 0.108 2.7432 1:96 0.144 3.6576 1:200 0.300 7.6200 1:350 0.525 13.335 So silkspan is a reasonable scale material for sails at scales from 1:40 to 1:96. It may be a bit too thin for 1:24, and too thick for 1:200. Another thing you might try is parchment paper (used for cooking). It is only 0.0005 inch (0.0127 mm) thick. The resulting scale thicknesses are 1/3 of what is shown for silkspan. It might work for scales down to 1:200. However, it is fairly stiff and might resist any complex shaping - especially for furled sails.

Kevin-the-lubber Posted April 24 Share #92 Posted April 24 Apologies if I'm misunderstanding but isn't that table the wrong way round? I don't think the sail material would get thicker as the scale gets smaller! I don't know what the sailcloth thickness would be at 1:1 but if I assume roughly 1mm, then: Scale mm inch 1:1 1.000 0.0394 1:24 0.042 0.0016 1:48 0.021 0.0008 1:64 0.016 0.0006 1:72 0.014 0.0005 1:96 0.010 0.0004 1:200 0.005 0.0002 1:350 0.003 0.0001 Tissue is about 0.05mm so true to scale at 1:24, though it seems to give quite a credible representation at other scales.
