In one of the issues awhile back there was a write up about a guy who said he increased the draw weight of a bow by some ten pounds by applying antler shavings mixed with hide glue to the belly of a bow. Has anyone else ever tried that, and what results did you get? It made me wonder as I have never seen anyone on here talk about this process.

Would make sense, I mean that's what Grozer uses in their "biocomposite" bows, they use ground up horn in a resin for their horn bellies. Sure wish their marketing were clearer about that though, lots of folks think they are using real horn.
-
shavings are probably not going to get you the compression factor that is needed,, the conglomerate that is used in Grozer bows, having horn and matrix mix, is more of chunk shaped and sizes, knowing the ratio is very important,
good luck though, please keep us informed with your progress

Wasn't grozer having problems with the biocomposites failing somewhat?
-
While a small amount of antler shavings. Helps with the glue to hold it together. Cooketarrow did this to all his hid glue. He also add a dryed root bark to his glue. I'd tell you but I'd have to kill you.
But like jame's said there no compression in shavings.

So then how would this increase the draw weight 10 pounds? that is my question. Is it a viable method for increasing weight on a bow? i have lots of antler at my disposal, Far more than horn, or sinew.

Even if it did add 10# to the draw weight the physical weight of the antler and glue would decrease cast. If you need to add to the draw weigh add a belly lam of a compression strong wood like osage or ipe and re-tiller.

I've only come in under weight once, and that was fixed with a sinew back. I just found it strange in an article in the magazine, and had never heard of anyone doing it, so I was curious if it really was a thing. If it was, well then I would have something to try. Seeing as it might be, but none of the guys here who's experience and opinions I value and trust, I will have to put it in the "Maybe when I don't have anything better to do" file.

That just shows you can't always beleive what you read.

That is why I was surprised to read it in Primitive archer!

Which issue? Not the bow soaked in salt water and buffalo urine?
-
Might it be some materials are more efficient at what they do than others.Per mass weight of themselves for what they do.I know epoxy has a modulus.Be it compression or tension.
-
Putting the composite materials into more stressful profiles to get better performance out of them has everything to do with this too.

I read that in Primitive Archer also. It was volume 24 issue 1 / February - March 2016. In primitive ethics and logic. By Thomas Holt
