    Laminating crossbow limbs

    Post by Hermit on Sat Sep 21, 2013 11:09 pm

    There are 2 types of resins available for use in fibreglass moulding.One is polyester.This resin is readily available,and fairly cheap.I think it is commonly used in crossbow prods and limbs,and seems to work well in solid form.The other is marine epoxy,the best known being West system epoxy.The reason that marine epoxy is different,is because polyester resin tends to 'float' on top of wood,and not soak in a fibreglass sheathed wooden hull can 'deglove',and the fibreglass come away from the hull.Marine epoxy soaks into the wood and bonds to it much better.With regard to laminated wood and fibreglass crossbow limbs,it seems to me that marine epoxy would do a better job.Marine epoxy does have one fault that polyester resin does'nt,it needs to be painted or varnished,as the U.V. rays in sunlight will cause it to break down.Marine epoxy is more expensive than polyester.

    Good analysis of epoxies there, Hermit.  Since I live on a boat at a marina, access to marine epoxy is relatively easy and inexpensive for me -- my friends wouldn't mind me 'borrowing' a brushload or two while they're deeply involved in 'glassing a deck with a gallon of epoxy.

    Strangely enough, I'd say the vast majority of crossbow builders don't make wood-glass laminates although it should be an easy setup to make a simple slightly recurved molds for a couple different sizes out of a piece of 2x4.

    Ea-40 smooth-on is the best bow glue I have found. I have used marine epoxy, standard fiberglass epoxy and a few others.
