My horn bow build-a-long
DC:
The glue joint appears solid. There are bits of the horn still glued solidly in the bottom of the grooves. The horn just self destructed. I'm very impressed by the strength of the glue joint. I've convinced myself that the design was the problem so the other limb is probably just waiting to break. Moot point anyway I'm soaking the sinew off as we speak. It will be interesting to see what the actual thicknesses of the three layers are. I'm still debating what to do next but I don't have any perfect maple. I know of a tree and it's just about loose bark season so I may cut it. I would have to make a decision on what to make so I can steam bend it while it's green.

I remember James Parker and his brother in law(disowned), Vinson Minor trying to brace for the first time James' first Asiatic horn bow(90#) and breaking it in the process. There were a few choice words blurted out.
Too bad your bow broke, DC. Lots of hard work in it I'm sure. Have you preformed an autopsy?
DC:
I think it was my design Pat. I misunderstood and glued a bunch of reflex into the sal area when I glued the core and horn. This put too much stress on the horn when I tried to bend it. The horn just exploded. The inside of the horn stayed glued to the core and the outside popped off so I'm confident that the glue joint was good. I'm soaking it to get the sinew off. It's been soaking for 4 days now and the sinew is starting to peel off in big pieces. The horn is just starting to lift out of the grooves where it tapers right out. This hide glue is good stuff.

Dc If the horn had been sound you would be amazed what a composite limb can take. Remember what Adam says about this subject. It wasn't the design.

OK, now I'm confused. You mentioned early on with the build that there was a problem with my bow. Adam says not to put too much reflex in the sal. I thought that was it. On a side point when I was first trying to brace it and it flip flopped the limb that bent the most was the one that broke.
