I believe Gordon use Vinylester and glass fibers and that BP use epoxy and glass fibers. I do not know how that effects stiffness, if any.

I have heard that black glass is a bit stiffer but it takes a chrono to tell the difference. :bigsmyl:

My only beef with the whole thing is: from the same manufacturer, there shouldn't be any difference in stiffness between two colors (or lack thereof) in the fiberglass.  I never had that problem with what built using glass made by Gordon's.  It has happened twice actually, the first one I thought maybe my caliper was off a bit when making the cores, but it wasn't, I check, I had the stack right where it needed to be. But the sad part with the first time; was the guy sent me some veneers he had, to use on the bow he wanted me to build, and it came out light.  I had to shorten it some to get his draw weight.   He told me no problem, but I could tell he wasn't all that happy about it.  I wasn't, I know that much.   

In the future, I think I'll use the bb glass if I'm making something that doesn't need to be at a draw weight somebody ordered.  I got too much going on to have to make additional calculations.   It is more clear, but most of the guys I deal with would rather have the draw weight right, and the length right.

I was there talked with them. Not sure what will happen they say they are aware of the issue.  He said they are working on it.  I have always found Henry a bit arrogant, But that just may be him having a trouble with the language difference so not sure if he even believes there is a problem or not

It is def clear!!  :thumbsup: And if it stays constant, I don't mind adding 4# to stack.  From what I can tell it doesn't make much diff on performance.
Stay sharp, Kenny.

I am completely in agreement with you Kenny (cuz I build soooo many bows per year  :laughing: ) but I have to say I am concerned about consistency. I think it's been mentioned earlier but are we sure that it will always be a 4# addition the stack for say a 45# bow? Or will the next one have to add 6#.

Oh sure if you read it that way  :goldtooth:. I took it to mean if the clarity stays constant. :banghead:

Tim Cosgrove said some bowyers Black widow for intance say it has also been inconsistant with in a roll. Some bows have been light some have came out heavy.   But it is very clear that we love.   Just wish Gordons would up there game but I don't see that happening.  Would rather buy a US product

Don't hold your breath on this one. Gordon composites was bought by PolyOne corporation in 2016. It's quite a large corp. with manufacturing locations throughout the World! Like any large corp. they will be looking to increase profits at some point and that means moving the manufacturing out of this country.
