Wow !! what a hinge. Dont know how you made that but it looks like it would be extremely stable allowing only lateral movement of the swimbait sections. Is there any binding at all?

John- This is a bit confusing, but I posted a reply to questions by 'bbduc' in the HB Gallery 'First Swim Bait Green/pearl', but after typing a reply could not load pictures, so had to load them here, sorry for the confusion- I think I stuffed up here.pete

Absolutely ingenious :yay:, Pete !

I have cracked my brain ocassionally on a similar hinge , made some brief sketches , but could not get a clue of it(haven't even tried to build one for testing) .

If the hinge is moved sideward , does one part not move up,-or downward according to the pitch of the coils ?

And I suppose , that you just interlock the two parts by pushing them together in the position shown , the pitched coils are sufficiently accurate to accommodate one another ?

A truly great design , hats off to you:yes: !

diemai- This is the text from the gallery post, hope it explains it a bit, sorry but it's very simple to make, but very complicated to explain-

I have done quite a bit of searching, and can't find anything like this. Essentially it's a 'double helix', which is a spiral within a spiral, made with hard S/S .9mm Mig wire, and took about four nights in the shed to 'perfect' it, and four days at work thinking about it, with many yards of twisted stainless wire wire, laying on the shed floor. Because they are made with a double helix, I have decided to call them the DNA Hinge .

Once the sequence was cracked they are very simple to make, and made with this wire (.9mm), have a joint, or barrel width of 2.7mm (.106299

Pete, Thanks for posting the pics and the detailed "how to".

You're right though when you try to explain it, it's difficult but you did a fine job. For me a picture is truly worth a thousand words.

I think I'll grab a few yards of wire, a beer, turn a game on the tube and take a run at making a set of these critters. I may need more beer.
