I need to create oval bezel settings for a set of six 18x 25mm
The style is southwestern, somewhat “concho-like”. I’m also planning
some decorative wire work to go around the outside of the setting in
concentric rings, to be soldered onto the backplate. So they will
also need to be ovals of the same proportions, but larger still.
As far as I can tell, commercial mandrels don’t come in this size -
it is too large for a ring mandrel and too small for a bracelet
mandrel. This is a problem for me because I am accustomed to
hammering the bezel/decorative concentric wire rings on a mandrel
after soldering in order to achieve the correct shape and size (I
always use calibrated cabochons).
Any advice on how to either make a mandrel or get by without one?
