Rob, I love the cow sinew....especially since you had already shredded it.
This is my third sinew backed bows with it. Thanks again.
Brad, I didn't weigh the sinew. I just put down one course, let it cure until transparent and fill in the thin spots with a second course and if necessary smooth out with a third course.
Bill, you probably can speed dry sinew. I doubt that a sinewed bow ever cures out completely in humid areas. In dry climates it can increase in weight for a year or more as it dries/cures.
Once I've added all the sinew I'll place the bow over our hot water heater for 3 to 4 weeks, add a snake skin cover and place it back for another couple of weeks. I prefer a long cure time, others take a shorter route.
Matt, you should have seen the yellow water running down the drain. I like using the Dawn wash and boiling water rinse because it "wets" the wood and I think it helps the hide glue sink into the wood better.
Stay tuned James.
