Over the past few months I have created over a hundred wax models for silver rings. I have not cast them yet as I have recently upgraded to a Neutec J2R-CE casting machine that has not yet arrived. As I was attaching a runner to a model I had a moment of panic, “Am I using the right gauge wax?” I have been using 4.1mm (6 ga. wax wire).
Most of my designs are not very bulky and are connected to the tree with only 1 runner. My question is: what is the ‘standard runner size’ that you reach for when sprueing up a ring model? I understand that “it depends” on the size and design of the model, but what is your ‘base wax-wire size?’ and… should I be using a runner with a reservoir as a matter of standard practice on all models?
