This ugly carp skinned bow is American elm, 66" ntn, 1 3/4" wide at the fades tapering to 5/8" nocks, 47# @ 28".  I toasted it into reflex and recurved it, but I lost the reflex and a lot of my recurves during tillering.  The backing is common carp skins.  I put them on green, (freshly fleshed) using TBIII glue.  The bow was shooting quite nicely at 50# @ 28" before I put the skins on.  It lost 3# because of the thick, heavy skins and too much glue.  Oops!  Guess I should have stretched and dried the skins and sanded them thinner. This bow is pretty slow and not exactly a joy to shoot, but I learned a lot about tillering recurves and fish skin backing from the experience.  Maybe I can kill a carp with it next spring.
