summitlures,
There are two basic types of hinges that I've used, with success.
Back to back screw eye/wire loops, and screw eye/wire loop with hinge pins.
Depending on your skill level, the material you use to build your lures, and what's available to you in terms of lure building supplies, both these types of hinges will work.
Rofish posted pictures of twist wire hinges used in Europe, and I'm sure there are lots of clever people out there with their own ideas.
And JRHopkins has his own unique hinge that works.
I now use the screw eye/hinge pin method, because it works for me. I can adjust the width of the joint by adjusting the depth the screw eye is inserted, with the finer threads making small adjustments easier, and the hinge pin of sst spinner bait wire, with one end bent to 90 degrees, gives me the ability to take my lures back apart for "service".
I'm still learning, so some of my past efforts now require tuneups, where previous paint schemes, gluing methods, or top coating efforts have failed, for one reason or another.
I don't sell my lures, so I have been able to learn as I go, without worrying about customer satisfaction.
Aside from my weekly fishing buddy, who I've given lures to, and who doesn't hesitate to make "constructive criticism" and request customer service, I'm the only one I have to please.
Correction. Me and the fish!
