The following "hand-activated, metal pushers" are famous with pushing metal against & over gemstones. In this essay, I will briefly explain how to use them in Gemstone Setting.
In this close-up photo of using a round bur to make a recess that will cover a claw to be 'gently' moved. It is advisable not to make the hole too wide, or even too deep, lest it could be not operable.
In preparation of a 'pushing tool', the front-face needs to be indented with a hole larger than the size of the claw. This recess will fit easily over the tip over the claw(s).
The hole can be created with the help of a round bur, I don't approve of a large tool face as if it was made larger I wouldn't be able to see where the claw is being used.
It is better to 'shape the tool' face just slightly larger than the hole in question.
I use different 'shapes and sizes' of handles for easier identification at a moments notice.
If the need is to use a Steel pusher, then the 'face' needs to be prepared for the 'pushing' to take effect.
I would use a "Separating Disk" of 3/4 inch diameter to cut little grooves into the steel face. This will eventually grip the claw and prevent any slippage when being used. This will only have a 'textured' face, but it shouldn't be made too deep into the steel.
I always keep my three "coloured handles" kept separate for easier identification in my setting bench. A 'freshly-contoured, soft metal face' is the most important aspect of using these pushers.
If the hole for pushing is getting too worn, then stop and re-drill the hole 'when and where' needed.
We need to have the metal moved, but no little marks remaining on the claws.
This Copper pushing tool is so badly worn, that it needs to be completely refurbished.
Brass doesn't need to be repaired too often, as it is quite a hard substance and resilient to being worn as often as Copper.
I'm hoping that this tutorial-essay helps you with using these 'metal pushers'.
