Hello
Is it possible to make, say, a round tapered collet for an 8mm stone from a strip of sheet approx 1 cm x 3 cm, soldered, then punched in a plate?
I'm trying to work out the cheapest way of making one and am comparing tubing, strip of sheet (above), piercing an arc shape from sheet (creates wastage) or doing one in base metal then getting it cast up. Strip of sheet seems to come up cheapest for silver, and casting from base seems to come up cheapest for gold.
I'm struggling with the maths..
Thanks
