Hi, here I put rope diameters (above mentioned) .

Many thanks for your advice. I think you have confirmed what I had worked out from looking at pictures of model barges and other craft, however the very comprehensive dimensions you have given on facebook are very welcome and will help me a lot.

Hi,
on Facebook I have added for you to the dimensions of the rigging corresponding rope diameters for the 1:24 model. I think the wires are more suitable for a static model. On my models I used black waxed cotton(?) string with a diameter of 1 mm for shrouds and fore stay. For other ropes I use cotton strings and cords produced by ropewalk . For main sheet , vangs and jibsheets I use braided fishing lines.
Ivor Bittle reccommended black leather strings for main shrouds

Hull is a 30" generic Mastman hull. Will be RC. I have all but finished the hull, now making spars. Photos I have seen all look like rigging rope, available from various sources, Mastman etc. but I was wondering if it would be better if I used a wire. if so, what do I use. Cornwall model boats don't seem to list a wire. Bear in mind, difference in thickness for mainmast rigging to topmast. Any ideas?

Question, is this intended to be a scale static model or are you building a sailing RC model?
