Well, getting ready to try my hand at sinew. Not sure if I should mix teh back sinew with the leg sinew. The back sinew seems much stiffer. I can't believe how much work this is. I have a osage that is a little light at 40lbs. I plan on piking the tips bymaking the bow 62" instead of 65". And figured with this sinew, with 3 courses, I might be able to get her back up to 50ish.
Have you reflexed the tips any. Usually you can get about 10 more pounds when you reflex. Osage is real easy to reflex with a heat gun. Then when you sinew, it will hold the reflex better and give you more pop.
