Is this a good deal for roving?

[DualCore]

Hi all, I was poking around on Ebay this morning and saw this pack of roving and I was wondering if this would be a good deal?

25lb pack! 18-24 oz Fiberglass Cloth Mat Woven Roving!
Premium 18 and 24 ounce per square yard HEAVY FIBERGLASS CLOTH - 150 square foot bundles
$9.95 + $19.31 (shipping) = $29.26

I would be using it for a transom and stringers using Poly resin.

Re: Is this a good deal for roving?

That's the stuff I've used. It's nice, but keep in mind you don't get a continuous square sheet, you get edge cutouts from manufacturing.

The last time I bought a 25 lb box I got biaxial cloth (better than roving IMHO) and most of the pieces were between 2 and 6 feet across in the widest spot, narrowing in a triangle to something small, like a few inches.

Fantastic stuff for tabbing in things and building up patches and such quickly, or experimenting with molding glass items, or for anything else that can use smaller pieces of glass.

It's not so great for covering anything since you'll end up with a jigsaw of pieces that won't be as strong as a single sheet.

For a transom I'd get a sheet/roll of "new" roving and a box of this stuff.

This is a ridiculously low price for what you get, by the way.

PS: You reminded me to buy some more of this stuff for my restore job

Re: Is this a good deal for roving?

Erik, I was looking at the boxes of Biaxial too, like this one:

PREMIUM BIAXIAL FIBERGLASS CLOTH - 113 SQUARE FEET

32oz per square yard Biaxial weave (+45/-45) with Heavy Mat. US $18.58

But I'm not sure what 32oz translates to, is that 1708/1808/2408/etc... I'm still fuzzy on what weight I need. I was thinking to use it for tabbing (transom/stringers/sole) and then covering with whole sheets from US composites. Do you think I would be able to get long enough pieces to tab in my stringers from a box like this? I'd like to be able to save a couple of bucks on supplies but not at the expense of a quality job...
