Re metal part. To play a vertical master would you not want an upside down U shaped stylus to fit over the inverted, hill-and -dale groove? Such as the fancy term you used, I think is what you mean, or are you staying two trunicated styli that ride both sides of the groove. Mostly likely play them back on a liner tracking turn table. You could make epoxy resin test pressings from them too Norman B should be able to help you do that, since they are making new Diamond Discs. It might be possible to make a metallic soap pressing I can practice this, with a regular lateral 78 stamper that I have and see if I can get it down to a science and let you. I imagine if the wax is fildterd 4 times it should be pure enough for a clean copy, and almost like playing a wax master.
