Basic trout spiinners are simply some sort of weighted body strung on fine, stiff wire with a clevis and spinner blade at one end and a hook at the other. It's as easy as it sounds, especially after you've practiced making small, neat wire loops with round-nose pliers. Once again, it's easiest to start by copying a favorite commercial lure, which makes ordering the right component sizes very simple. Make sure to use wire-type clevises, rather than the folded, stirrup type that don't spin as freely. Be careful, too, that the spinner blade has ample clearance to spin below the top wire loop without binding. Finally, the small hollow brass bead often used as a bearing surface on the wire between the body and the spinner-blade clevis sometimes has an imperfection. These beads are usually plated, and the plating process can leave a small burr or point at the edge of the bead that will cause the spinner blade to bind. Check your beads carefully before assembly.
