Parnelli:

Could you provide either drawings or photos Of your 'board'? I have been making furled leaders for about for years now, after Skip Shorb showed me his board and how to do it. Regrettably, I am thoroughly stumped on your procedure.

With respect to a spreadsheet, it will do for you, with just a few clicks of the mouse, what a calculator takes much more time to do.

The info on the Mercerized Cotton Thread is very interesting. Does it not rot rather rapidly if the lacquer finish gets cracked, and water gets in to it?

Cheers!
