Woodreaux I must congratulate you on how tidy you keep your work shop. All my working life before retirement tidiness was a thing I always aspired to but missed by a mile. Even my apprentices called my work bench "the Phoenix nest" though in my defence what came off it was always correct. And things have not changed even after I retired. Just one point about making moulds for casting metal out of metal the one major drawback is the metal mould must be the same temperature or a little hotter than the liquid metal you pour in, not doing this the mould becomes a chill with the resulting casting being distorted and having parts missing. Plaster and sand moulds work well and that is why they are still in use today because they do not take heat out of the casting metal to cause a problem, the use of metal moulds is another world of skill in its self.
The only lessons in my life I truly did learn from where the ones I paid for!

Are bronze/copper jaws too hard for action holding?

That's a slight of camera! If you could see it in real life, you'd see that it's a complete mess. I've got another project going at the moment, then I'm hoping to get the shop into sustainable order. The vise Jaws were a diversion from a mother in law remodel that is taking all my time at the moment.
I see what you mean about the metal molds acting as a heat sink. Am I correct in thinking that shouldn't be a problem with my frying pan method since the cast iron is both crucible and mold?

Are bronze/copper jaws too hard for action holding? Should be ok in terms of marring steel, I would think. I don't know enough about holding power to comment, except that the traditional method seems to have been lead jaws for both holding power and non marring.

Woodreaux your method of casting the lead is perfect for the outcome you want. Though Lead vice jaw covers do look the part though if the truth be known I prefer to use Red fibre jaw covers my self because they are quick to change and take a lot more rough treatment than Lead. And when the fibre gives up and starts to disintegrate you can replace it with wood or cork, cork versions are particularly good for holding plastic without marking it and if the cork layer is thick enough you can hold a gun stock without marking it.
