Native American inspired horn bow
bosko:
Aaron: I put the sinew in two sessions, first 3 layers with about 20% hide glue (about 45 g of sinew) and the last sessions 1 layer with about 16% hide glue. From my experience with making asiatic style bows I found out that less concentrated glue for the last layer is better, but the problem is I never glued sinew directly to horn, so I hope that it won´t come off. I really hope that it would be stable, because there is no wood core and I do not have any experience with just horn and sinew bows, so I rather sacrifice some speed for stability for the first one.
Aaron H:
Did you size the horn first with any thinner glue? With horn being very dense, I'd be worried that the 20% hide glue wouldn't penetrate deep enough into the horn.
bosko:
Well Aaron I do not recall it exactly, but I believe that I put 3 or was it 4 coats of 6-7% hide glue for the sizeing and the horn was a bit glossy before I put sinew on. I learned the hard way that the horn must be sized well with thin glue, my first 3 turkish horn bows had glue failure and the horn delaminated from the wooden core. Aaron you think that 20% hide glue is to thick for the first layer of sinew. In Adam Karpowicz's book he suggests the glue concentration between 20-25%, but yes I know in asiatic style bows you glue the sinew to wood and really I have zero knowledge glueing sinew directly to horn. So Aaron I really hope you are wrong :D , because if not, we have a fast breaker here, not a fast shooter :P
Aaron H:
I hope I am wrong too bosko. I think if you used the 6-7% glue first, and got the horn glossy from the glue before you added any sinew, then you should be fine.
bosko:
Aaron: I even roughed up the surface of the horn before applying thin coats of hide glue. So I really hope it would be fine. Thanks Aaron for your advices, they are much appreciated. If this won't work, than I will be using thinner glue for the first layer of sinew next time. I will be posting the progress as I go.
