Furnaces to wooden sail boats.
I was reading The Riggers Apprentice and I came across Grommets. Nylon Rope is a poor starting point, but it was the only three strand I had. It simply does not hold it's lay, and it unravels faster than a middle east peace accord. I did soak it in a mix of water and hair gel - not sure that helped much, but it smells odd now. I also tied off each of the three strands with constrictor knots to stop each strand unravelling. The small one was my first try. I should have tapered the strands as I tucked them.
I did taper the strands on the second one, it came out a bit better.
A copy of The Sail Makers Apprentice just arrived, so I have reading material for a few weeks.
