I made a long bow and used this fiberglass on the outside of the bow. Glued it with epoxy and for some dumb reason there may have been an area not holding, therefore spliting. very disapointing.

The product is exactly what I hoped for and more. I didn't expect it to be so strong and yet so flexible. My very first bow turned out great. I used Smooth-On EA40 epoxy and it was the perfect combination of material.

This is a great quality product at a great price. I have used this glass to build a couple of very nice longbows. This glass is easy to work with, adds power to your bow, is very durable and looks great either black or clear!

I used the glass to build a deflex/reflex long bow.I ordered 1 strip 1 1/2x72x.040 and 1 strip1 1/2x72x.050.They came marked right,but both were .050.It didn't hurt me as I grind some of my laminations anyway.They worked fine and made a sharp looking bow.

If I am using Gordon's Bo-Tuff Fiberglass for a red oak Hun style bow, which is 1/4 inch thick, 1 1/2 inch wide, 24-inch limbs x 2, and two 9 inch siyahs, how much weight would .04/.05 thickness would it add to the bow if I am adding one layer to the back
It's difficult to give an exact number as it depends on the bow

It's difficult to give an exact number as it depends on the bow itself, the style, etc. I would guess that you might gain about 5 pounds. But really tough to give a number.

Exact weight may be 1 to1 1/2 lbs to heaviness if that, draw weight will still depend on limb design. I have made several hickory long bow backed with this fiberglass and they make fantastic bows.

You can do this, but it will not add to the performance of the bow. That comes from the backing. It will not hurt anything, but not helping either.

how long are the strips. I am in the process of building a holmegaard bow and it seems a bit low in the draw weight so I think putting fiberglass on the back would help but how thick should it be (end weight approx 45-50 lbs)
These are 72" long

You will add about 5-10# depending on the thickness of the glass. I use the Smooth On EA 40 epoxy for gluing up bows.

It really depend on the type of bow and personal preference, but it is not required that you put fiberglass on the belly of the bow. Yes, you can cut the fiberglass in half.

I always rough the gluing surface up and then wipe it down with something like Acetone. If you just used as is, you probably wouldn't notice any difference, but I would not risk a failed glue joint by not prepping it.

I don’t think so, Shea. Fiberglass generally requires an epoxy adhesive which matches the strength of the resin already in the fiberglass. Tite bond is good glue for what it’s made for, but not this.

Personally, I wouldn't try it. Smooth On epoxy cured for 16+ hours at 160 degrees is a sure thing. You will never have to worry about de-lamination.

The tite bond glues are excellent for rawhide or skins but they will not hold the fiberglass. You will need to use a two part epoxy and it must be flexible. I use and highly recommend the smooth on.
