[bolger] Re: Xynole

I'd be concerned that the xynole would not follow the inside or outside corners
at the edges of the planks. Id' try laying up a small area and see if it
followed the corners. Pull it off and wipe off the resin before it cures. If
there's a problem, you might need to round the edges of the planks or apply a
small fillet before laying on the xynole.

Xynole is itself lightweight stuff, by which I mean it's not very
dense. (Supposed to be a breaze to work with and very tough standing up
to rocks and stuff.) Hence, you should compare the 4 ounce stuff
Defender sells (at least I recall the only weight they sell is 4 oz) to
8 ounce fiberglass. Both are supposed to be equally durable, but both
take the similar ammounts of epoxy to fill.

Thanks for the info. It sounds good enough to try. We have very shallow
water, and equally hard rocks, so if the boat is a little heavy, I won't be
overly concerned. I'm going for it.

Chuck,
I do know a little about Xynole, it's the canoe I don't know anything
about (no sail). I am told that Xynole takes "much more" resin to fill the
weave, so for me this would raise the question of weight. How heavy is too
heavy for a canoe?? What is the weight of resin you would use for a regular
glass canoe? The catalog says that Xynole is available in 4 oz only and
Defender gives the following info:
Glass Xynole
24000 15000 Flexural strength PSI
79000 61000 Tensile strength
322 88 Stiffness
fair good Abrasion resistance
fair good resin impregnation
I am told that the Xynole is much nicer to sand, with none of the usual
FG itch afterwards.
Regards, Warren
Since there is so much knowledge about this material in the group, I will
pose the following question:
Would xynole be suitable for covering the outside of a lapstrake ply canoe?
