hi,
what's the scale of this gorgeous shield?
It is pierced and engraved?
Cynthia

Crquack,
Thanks for the comment. It took quite a while. It is made from a wax carving, had a couple weeks of straight carving into it.
I absolutely love your sundials, I could see using my process for something like that.
Cheers
Sam

So Sam,
what is the scale here?I can't tell the diameter at all.
And when you say you carved it in wax,is it then a lost wax casting? In silver?
Is that a variation of the Celtic "running dog"pattern or your own invention?
Lovely job...

Thank you. But I have a long way to go and much to learn before I equal this.

Sam,

It is a nice piece and I'd like to hear more about your electroforming setup. Obviously it works and it is a very interesting process in general, so can you fill us in on some of the specifics of your setup?

Rich

Feel free to say 'no' if this is a trade secret, but I would like to know what you use to coat your wax model to get the necessary electrical conductivity as a pre-requisite to electroforming.

I looked into this briefly as a way of making my sundial faces but could not find anything that was easily available or cheap enough.

OTOH I have had reasonable success with electro-etching :-)

Crquack,

When I did some copper electro-forming years ago I simply used metallic silver (aluminum) spray paint over the model to make it conductive. This worked fine in the cupricfluoboric acid forming bath I was using, though I cant say it would work in every possible solution.

Rich

Thanks. This is new since I looked last. Looking at the price and the kerfaffle using it (no brushing!) you'd better be serious about your work.

Which you clearly are.

I shall file away for future reference.
