I haven't ordered lam stuff in a couple years and I just looked at Binghams and Fedoras and both have Gordon E glass ULS and UL....whats this scrim stuff their talking about and what doe sit add/subtract form performance????
second question....I'm building a takedown recurve shooting for around 60#s....whats your opinion....actionboo or cane???
-
er.....anyone?
-
Scrim is the horizontal weave within the glass which helps stabilize laterally.
Only ever built lb so ?? on ?#2.
-
i recomand actionboo for a recurve.
the scrimm are layers of glass that run perpenicular
to the glasslam.
usualy about 10 percent.
in my opinion its not the way to go.
the glass that i use is 100 percent unidirektional.
it just performace better.

both these gentlemen are correct about the glass but I disagree with shantam. The glass with scrim is a much stronger and stable glass than without. the only advantage to glass without scrim is that is a bit clearer, more transparent but it is not worth the trade off. especialy for a recurve.
-
the main advantage of glass without scrimm ist
speed.
compared to the glass from gordon i can build my
limps 0.00394" thinner.
i stick with the no scrim glas.
but since i only build longbows,i dont no if you need the scrim for a recurve.
just my point of view

Highstick, I talked to one of the suppliers of Gordon Glass about this. What I got out of the conversation was this, the scrim glass is a little bit better grade because of the unidirectional support. He said when handling it in sheets it was definately less likely to brake. BUT, once it was cut down to 1 1/2" or 2" it really didn't make that much of a difference.
That being said I always use the glass with scrim because in my experience I've found it's usually looks a little better and has fewer blemishes or streaks in it.

I use ULS in all my bows, just cutting it one can see the UL isnt as strong, some say it doesnt make a difference in longbows but ULS is highly recommended in recurves for the added stability of the scrim layer. Both have streaks and spots from time to time, its just the way it is with clear these days.
-
thnx for the info guys! I'll be placing the order tomorrow and will let you know how it goes.

I only use glass with scrim. It keeps linial glass cracks to a minimum. In otherwords the bow will last longer. It torsionally stabilizes the bow limb and cuts down on vibration , Its better quality glass with fewer streaks and spots. Just all around better glass. Only problem is that it only comes in .043 and .o49 thickness. Directional glass splits much easier. In fact there is a Vision on here ritht now with that very problem. They used directional glass on a fast flight bow and the fastflight over time splits the glass and eventually the limb. I recommend uls God Bless and have a great time , Steve Tallant , EagleWing Bows

How long has ULS been offered? I can only remember seeing it the last few years.
I've always used UL glass in the 40+ longbows I've made. Never had a problem with UL but have a problem with spending over 20.00 for a single piece of glass. Man that stuff is expensive. Chad
