Hey there,
I'm working on a brooch design and I wondered if it is worth elevating the tube for the hinge as I've seen some broochs or not and why you'd choose to do that or not do it?

I,m guessing it would depend on the design. I don't personally but not seen reason to (I might well be missing something though!)
Yes you do not say what kind of hinge you are using Kathryn.
Most bought in hinges are already a little higher than the back. This allows room for thicker fabric when the pins are fastened and allows for a shallow rest to add spring to the pins and keep them tight against the catch.
My picture shows this using bought in findings and a riveted stainless steel pin. Dennis
Opps that was very unhelpful of me. I'm making one using tube and steel wire, I'm still trying to decide if it need two pins for the weight or it is fine with one. I found this and I was just curious why some are elevated and some aren't but I think the thicker fabric might be the answer.
The 3rd and 4th picture difference of having or lacking a plinth as they describe it was what made me wonder.

For double pins my solution is to use a tube within a tube for the hinge. This raises it as mentioned with no need to solder the inner tube.
The springiness is created by filing away a portion at each end for the pins to rest on. Dennis.
That's clever and sounds more stable than a plinth.
I'm not sure I understand how you make the springiness mentioned, I'd that so they spring open when unlatched?

The inner tube fits the chosen pin wire and is out out of sight. The outer tube fits the inner tube and between them they raise the hinge.
You can ether cut away part of the outer tube as shown in my sketch for the pins to rest on. or simply add a metal strip. In either case they are as high as the centre of the pin, and that is enough to hold them up.
In fact it can be too much and need a little filing. Dennis.
Wow you did a diagram as well! Thanks that is amazing. I swear I want to blame baby brain for not getting that now I can see clearly what you meant and in the picture
That baby might be a warden of the Goldsmiths Company one day.
