Hi there
This forum is great. Here I am posting a question for a tiny hinge and the strange thing is I might even get a response or two. I need to hinge two pieces of 6mm steel bar. One is upright and horizontally on it. T formation. The easiest way to describe it is if you take a pen and hold it vertically and place another pen horizontal across the top of it. T From this position the two must be able to hinge so as to end up pretty much parallel. It sounds simple at first but its really not! Its a strange request but no better place to ask...Any ideas would be great. Thanks Steve |

Side by side parrellel? one on top of the other stacked parrallel? I can think of several types of inges, but I do not know if they would be small enough or if you would have to fab them up, think barrel hinge, or tab with an eyelet/rivet hinge, and it might even need more than one hinge conjoined to get hwat you want, I suggest building a paper model and then making 'origami' folds till you get where you want, then back up and see the connection locations and directions.
sorry not much help! kay

Thanks guys
I can't really describe it very well. I'll try again. take a bar and stand it upright. Place another on top of it to form a T shape as you look at it. Now as you see it take the left end of the horizontal and push it downwards. the right end lifts. The pivot point is the top left point of the upright bar. From a plan view both bars remain aligned so I suppose - stacked parallel. Two plates and a pin could work but I need to keep it all very small. I was hoping there exists a manufacturer of small hinged couplings or something. thanks for the interest Cheers Steve |

From what I think you are describing an "eyelet/rivet" combination as was previously mentioned sounds like your best bet. But then again I could simply be misunderstanding your need.

Consider eyeglass or jewelry hinges. Here is a company that makes them: http://www.bkoptical.com/products.shtml#Hinges
You may also be able to find a suitable hinge with some creative scavenging in those areas... maybe a tiny locket, a hinged clasp, or a pair of old sunglasses? You might have to modify with a small file or Dremmel tool, but I see no reason why it wouldn't work. Can't solder to steel, and screwing them in place is highly unlikely, but a touch of some serious epoxy, like PC7 just might work very well. If you plan to stress the joint, the hinge will likely give long before the PC7 would.

Hey Tabman,
I use a mini Oxy./Acetylene torch to silver solder with. You need the heat to get the piece to heat up hot enough for the solder to melt and give a good bond. Silver Solder actually gets cherry hot, so it recquires a lot more heat than your standard lead/tin type of solder. You can even Silver Solder Stainless steel which is a bonus!!!!! Hope this helps?

Thanks Mike. I learned to braze with a torch when I was a kid but don't have a gas rig now. I have a small MIG welder and a large soldering iron, a butane torch... the usual stuff. Does silver solder flow like lead solder??? Do you use a flux???

If you use silver bearing solder, it gives almost the same strength as silver solder but melts at a much lower temperature. It melts about the same as Rosin core solder.
Tabman is right if you can braze it will be the best but that take a little practice on something that small. Richard

Ok. I stand corrected, but I guess the question now would be, "Could a tiny hinge take the heat?"

Silver solder and the flux can be purchased at most good hardware stores.
