So im getting ready to sinew back a couple of bows and I really cant recall how many leg sinews I used on my other bows. I remember using about 4 for a 55 inch bow. The bows im backing are 55 inches and they will be elk leg sinew about 8 inch long. I just needed an estimate on how many to process for each bow. Its been some time since I sinewed a bow and the last one I did I used cow and moose sinew. As I recall cow sinew is extremely fiberous I couldnt believe how much fiber I took from it, it was exellent. Anyway any imput is appreciated.
