I never cared for 1/4 sawn osage but I use 1X2X72" slats all the time for backed bows. I don't like my bely slat any thinner than 3/4" because I don't like using a power lam to keep the handle from flexing. I prefer 1" think if I had someone sawing it for me. You can back osage with a lot of different woods, bamboo, maple, red oak, white oak, hickory. I would take all I could get. I will even buy some from you if you are selling any.
