Thinking about sinew
bjrogg:
Thanks Dave.
I really appreciate your response. I know I have a lot to learn here. I have never used hide glue so just figuring that out I’m sure will be a learning experience. Speaking of hide glue I still need to get some.
I did wash the sinew when I harvested it a couple years ago. It’s very dry now. I think my next step will be more separating and combing to get it hair like. Also weight and bundling.
In the meantime trying to get some hide glue. And set up some type of double heater.
Gotta few other things I have to do this weekend. I will magically transform into a Jolly St. Nick several times in the next ten days. Everyone knows how busy Santa gets this time of year
Thanks again for the support I’m thinking Santa will put you on the nice list.

No problem at all. Glad to help. As for hide glue you could make your own but it is very time consuming I found. It’s novelty wore off pretty quick. I just buy mine from 3 rivers archery. It’s the granular stuff and it holds very well. The mix instruction say 1:1 by volume that come with the glue. If buying from another place just stick with 1:1 ratio by volume for mix or basically all I do is put enough granular glue in my mason jar and put just enough water to cover the granular. Works every time. The other measure that works good too is by weight. I general use 2:3 ratio of dried glue to water by weight. This is what I stick with for horn glue ups. For sinew I go a little lighter 1:3 by volume. Some may say this is too light but I like it for sinew. Not all my glue in in small granular. My sturgeon glue is in bigger squares so I use the weight ratio instead. Still works good. Basically looking for a consistency of a med to light syrup thickness when hot. As you let it sit in double boiler it will get thicker as it looses moisture. Just tiny bit of water to get your consistency back to where you want. For my sizing ratio do this by volume again to get your 5% for at least first few coats. Doing the math it would be 1:20. This may seem ridiculously thin but you want it basically like water to start with for sizing. Then go to 1:10 ratio for rest of sizing coats. Heat up with radiant heat your limbs to really soak in the thin glue for those first few coats. As you get used to the glue and mixing you’ll get a good eye for the Color and consistency you want for subsequent bows. It’s not as mystical as it may appear. Good luck with it. Here’s my simple basic double boiler set up. The last pic is my latest haul for back and leg sinew.

Interesting thread. Maybe y’all can convince me to try one. My problem is patients. I’m sure it will turn out way cool.
