|Thanks for the response. I did find that excellent article you referred to and that is why I was questioning the correct sized fibre. Having referring me to Black Arts I had forgotten about, I now have other concerns on rubber hose, scoring, warping, cutless bearing, replacing my 2 blade fixed prop and many other topics referenced. Lots of time to plan my attack in the Spring.
Thanks to all those who have contributed to the site.
