Thanks. I am trying to keep it 'period', if not 100%, to the original plans, which I've managed to get a copy of, and it'd already been converted to r/c, so I've tried to tidy that up.
In remaking the wire rigging, I've been trying to get replacement 'thimbles', to go in the eyes.
The model has four stays, one in each corner, and no shrouds. For ease of dismantling/erecting, (I guess), two of the stays had rigging screws, while the other two were shorter with an extension of cord, tensioned with a bowsie. The thimbles act as a pulley block to allow free movement of the cord.
For some reason, these thimbles are not easy to obtain anymore, although Cornwall had some really tiny ones, way too small.
The chap in our local guitar shop kindly gave me a number of old strings, which use a bead , or ball end, as they're called, at the bridge end of the string. These are still a bit small, but should do.
