This is a method that can be used to bend loops in bare wire for making in-line spinners. Credits to gldnbear93 for sending me some photos of how he does wire loops in hard baits. I adapted his technique for making the loop in bare wire. Enjoy!
You will need needle nose, round nose, needle vice grips, standard vice grips, and side cutters. Ice cold Linenkugles is optional but highly recommended.. The round nose pliers are hard to find in your local hardware store but are key to making good loops. Knipex make a good set of heavy duty round nose pliers and you can find them by doing a search for "Knipex round nose pliers" on the web.
Bend a 45 degree angle in the wire leaving about 2.5" to work with on the end. The more you leave on the tag end, gives you the leverage you need to wrap the wire so don't cut yourself short.
Using the round nose pliers, wrap working end of wire around the pliers. The initial grip should be tight to the 45 degree bend you just made.
When you get about 1/2 way around the pliers, you will need to release your grip, rotate, and regrip with the pliers to allow the wire to fully wrap the jaws of the pliers.
Clamp the loop with needle nose vice grips perpindicular to the wire shaft then clamp the tag end with regular vice grips.
Make about 3 wraps around the wire shaft with the tag end. Again, leaving more to work with on the tag end gives you leverage and allows you more control to keep nice tight wraps stacked together.
Cut off extra with side cutters.
