Aware that making hide glue is difficult under paleo conditions I posted this question back in October-5-00 Still hoping someone will give it a try and report.
"Would someone try this experiment and report back:""
Blood is pretty good glue. The next time you have a few ounces of fresh blood would you try using it instead of hide glue while sinew-backing a bow? Blood glue was used to make plywood before the '40's. A small amount of lime powder was added. Possibly about 5%, possibly to make it somewhat water resistant, as with milk curd glue,"
Someone asked if the idea came from an bow-building book publishes in Transylvania. And someone worried that the blood would clot before use. Others that blood glue might be too weak.
My responses then:
"Blood doesn't clot in the animal, so maybe keeping it warm and away from the air... would hold it ... Some California Indians are reported to have used soaproot glue for sinew backing, about the weakest glue there is. And fish skin glue has been used, also pretty weak..."
So will someone give this a try?
