Looks just like the foam glue called "Gorilla Glue ". When I use it it has to be moistened on both surfaces. When it set it foams up like your picture. I have not tried it on bows yet. For woodworking though it is messy and foams out of joints that later have to be trimmed down. Not my favorite glue right now.Tim Baker wrote: Here's a piece of the mentioned hide glue foam:

I've got to sinew it first.
Here's some stats:
1 3/16" wide a widest.
1/4" at the nocks
4 3/8-oz before adding the glue belly.
5 1/2-oz after -- 1-1/8-oz of dried glue on the belly, about 1/4th the weight of the bare bow.
I'll apply the same 1-1/8-oz mass of sinew on the back. With the glue in the sinew the finish bow should be at about 7-oz.
As the glue dried it pulled itself into a bit of deflex. The bow will be pulled into several inches of reflex when applying the sinew, putting the glue belly into strong tension, a big compression safety head start when drawn.
This might be a totally dumb idea, the glue belly failing in compression, but maybe not. Way cool if it doesn't
The bow pulled into deflex by the glue.
from blancoh0: "All this gluing and testing and measuring ! I wonder if this would make the Native bow makers crazy ? I think and guess that they did not do all of this stuff. Not sure who or even when all this sinew stuff started. Same as when fire making was discovered. I am sure different methods were discovered at different times. Flint and steel, friction boarding, bow and spindle, etc... FYI "
