Yeah, it is harder with tb as it's thick and sticky. Maybe if you watered it down it would help? I tried sinewing with tb3 once, and will never try again. It dried on the outside but the sinew never dried on the inside. It was still squishy after a month. I will never do that again. It was not near as snappy as a sinew bow normally is, and took a lot of set. I just sinewed a bow a couple days ago with some hide glue I got from woodcraft. So far I am very pleased, looks and smells like the hide glue I used to make from sinew scraps. I almost got some that was labeled "industrial hide glue", but than I read all the warnings about ventilation and how not to come into contact with skin, etc. I found some other stuff though that was more expensive, but seemed to be just good old hide glue. It was much easier to make then cooking your own too, took an hour or so and it was ready to go.
