1st Boxes: proper sizing of hinge components & spring materials for catches
Posted 08 February 2011 - 12:52 PM
Secondly, I've seen pictures of spring components using copper, brass & silver, but I don't understand the considerations & processes that go into their fabrication.
I've worked almost entirely with steel over the years making cutlery, hand tools & ironwork. I'm relatively new to jewelry and have really enjoyed exploring this new world and its smaller scale-I find it very exciting (and am happy to see that many ferrous metalsmithing techniques transfer over to jewelry!). Thanks.

You want them to be sized, to support the weight and usage of the lid. and also that they are large enough so the can be solder properly in place and still look in keeping with the piece. You also want there to be enough material so you can Broach the holes to line up the hinge pin if it is slightly out of adjustment.
Then depending on your design the hing pin is made and installed the one end is rivet headed in place.
Each style and type are different.
As to springs music wire is preferred but hard drawn brass and nickle silver can be used. The other material has little spring and goes away fairly quickly (copper) in my experience.
Here is the best book for general information in the art metal area
I can't say enough about this book other then to say get the pro edition rite off the bat as most soon end up buying each edition as they have more info in them. He also has a book on boxes, hinges and lockets among others.
This book along with Oppi's second book are must haves
Here is my review of it
to the forum.

I will elaborate on Glen's comments about Tim McCreight's book called "The Metalsmith's Book of Boxes & Lockets". Although it does not give hard and fast rules on specific gauges etc. it does have a lot of good stuff on reinforcing the hinge area, how to construct a hinge, what's important, etc. Plus it's chockful of eye candy.
