Pearly may be right but its good to verify all the bones , Bow CSI...,lol , I personaly dont trust kiln dried lumber for backing , just because you really dont know how it was treated , I make my own air dried backing , core wood I have no problem with kiln dried but Im selective where its coming from , Jeff your getting a belt sander you have the jointer & band saw its pretty easy to make a make shift thickness sander out of one , Ben on here did a effective simple set up like that & the backing strips dry quickly if you dont have seasoned wood for it , at least eliminates the bone problems in the exspermentle world !
