I now have more items stuck together permanently than God ever intended! :D <br /><br />Must say though that the stringer install is going better than expected, although slower than I anticipated. That raises a curious question though..<br /><br />Should I attempt to duplicate the thickness of the layup that existed when the crummy factory stringers were laid up? I'm laying 1 layer of 1 1/2oz mat, followed by a overlaid layer of 17oz bi-axial, followed by 2 more layers of 1 1/2 oz mat, but it still seems thinner than what was originally there. I'll grant that the original was a mixture of mat and chopper glass, and was not adhered in many places, and not even wetted in more areas than was probably safe, but I still think it was much thicker (1/8" or so) than what I have now. <br /><br />BTW, it's stitched epoxy mat I'm using, I researched it thoroughly....<br /><br />Thanks!<br />Roger

Re: You have to love US Composites epoxy...

That particular lay up should yield about 1/8" to 3/16" total thickness if i remember correctly...<br /><br />If it were me, i would have added at least one more layer of biax, and would change the direction of the strands in the biax (i overbuild)... Biax is best put to use in two or more layers changing the orientation of the strands.. ;) <br /><br />Since your using epoxy, your probably ok as is (maybe add a 3'rd layer of mat)...
