Title: laminate glues
Post by: Beanbag on April 01, 2011, 09:37:00 AM
Was just over on the Pow Wow and a few guys mentioned that they used Gorrila glue to attach adapters to broadheads with good results. Has anyone tried/used the stuff for laminating? It's a polyurethane base and is pretty tough. I have used it for R/C aircraft wing laminating and it amazing how it stiffens up balsa wood. Just a tought. Jim G

Its crap...the foaming action creates too many voids in the glue line to deal with the stress put on a bow limb. Stay away from Gorilla glue for bow building applications.

I respectfully disagree with using this stuff in all bow building applications. The impact resistant GG Ca is excellent for tip overlays and even limb butt overlays that are not flexing too much.

i do not think i would use it for laminating limbs though... Smooth on is the way to go there.

Gorilla Glue doesn't mean what it used to.
Originally GG was just the polyurethane and that is no good for lams.
They now produce cyanoacrylate (super glue) and
aliphatic resin (Titebond type wood glue)
as well as duct tape and other products as they have extended their product line.
Each glue has it's proper application.

My bad on that one...I assumed he was talking about the polyurethane glue.  The CA (impact resistant super glue that Kirk was talking about) is indeed useful for overlays (handle and tip) I also use it for my inserts on carbon arrows.  So far so good on those but time and misses will tell.
