    Re: Tarring hemp

    If you are seriously thinking about tarring a boltrope you also have to consider what it does to the handling characteristics of the line. You don't just sew rope to the edge of a sail and be done...

    Re: thunderbird #2

    The color is Thunderbird blue (as in Ford Thunderbird). It's one of those colors that tends to be pretty questionable on a car as well - you can't miss it, but you're not at all sure you like it.

    Re: Tarring hemp

    Why do you want to tar the roping on a sail? It's just going to get all over it (and you) when you use it and it will make sewing the roping on a real pain in the ass. I could possibly see hemp on a...

    It could be done, but I'm not sure it will make you more efficient. If you store the proper amounts of resin and hardener in separate tubs and mix them as you go, you will need to be quite meticulous...

    Yes, you should always patch fiberglass by putting the smaller patch on first, then the larger one. It reduces the amount of excess resin in the patched area and will also go a long way toward...
