This is a different approach, but I am adapting yet another series
of techniques, so here we go.
I have cast some large cups, both in sterling and fine silver.
(total cast was about 800 grams, trimmed down to about 575 grams
after sprue and gate removal).
Now, one of the steps I am doing is machining these on a sherline
lathe - lets me superimpose a perfect machine circle on top of a
hammer finish, for contrast.
Anyone in the group have experience machining sterling, I am having
some trouble with “galling” when cutting.
