Since it is just for added bling in the clock, You may want to think about building up a bezel ring around the clock face or other flat parts. I don't know if this company ships to the UK, But it may be of interest for you to look and see what the have available in the silver, along with other base metals ,wire stamping etc. metalliferous Bezel wires stamped flat wire strip metalliferous silver home page All are PDF downloadable catalog pages, They do have an amazing amount of metals for modeling and jewelery and clock making. Or MadModdering, in addition to tools and other stuff you never knew you needed! Here in the states hallmarking has a different meaning then in your country. In general hallmarking is the same as a Makers Mark In the US since there currently is no law in the US requiring a Quality mark. The current standard is the National Gold and Silver Marketing Act the standards is 921 parts per thousand or .915fineness with solder taken into account. Plus if you quality stamp it it either has to have a registered trademark or makers mark, which if it doesn't (registered trademark or makers mark) the parties that produce the article is responsible, for producing fraudulently marked goods. And as you know, Silver, Mexican Sliver,German Silver, Indian Silver or any other names or markings are no guarantee that there is any silver content in the article. Since German Silver is the old name for nickle silver, which has no silver content at all. Silver from other western countries are marked with the parts per thousand numbers to denote the fineness of the silver content. The US and the old British Empire countries use the sterling standard. All though your registration of hallmarks etc. is more rigidly controlled and followed. The hallmark site in the above link is the best site on the net for information on the matter. |

Hi PTsideshow, yes, I believe our direct meaning of the term hallmarking is that the term "hall" refers to the assay hall in which the "mark" was stamped to guarantee purity. My understanding is that once I have a sponsors stamp, I then register for 10 years for £70. I can then drive to the assay hall (about 25 miles away for me) and wait while they test a sample of the metal and if they find it to be 995/1000 parts silver, will stamp it with the relevent marks. I really wouldn`t have a clue how to start building up a bezel but in retrospect, I do think that perhaps this would be the nicest parts to do. I`ll have to have a read about it. I`ve done some googling and other than making jewelry, I can`t find much on working with silver. I`ve seen a few vids of people working on making spoons and that is about it. I`ll keep searching and let you know how I get on. Of course with the cost of the silver being so high, I need to ensure I`m going to be able to make the parts I want before I go any further with the idea. Anyway...lots of time yet. I`m not going to attempt this until the clock is near finished. Chris |

All a bezel is is like the bezel that holds the watch or clock crystal in place. In jewelry it would hold the stone in place. I guess I should have said building up a multilevel silver ring around the clock face. Either with half round or assorted sized twisted wire. Using the bezel wire/strip or the open stamped wire. with the strip or twisted wire you can always do it up in copper to get an idea of what it would look like around the clock face edge. It would be a matter of doing a very clean silver solder job around build up sections. Plus there wouldn't be the outlay for the cost of the silver to find out you don't like it :doh: Brass wire and gas welding rod and strip would work too. Most of the jewelry supply houses here in the states sell it by the foot or ounce and they all have a pretty good idea of how much silver is in each inch let alone each foot. I'm sure they deal it the same way in your area. :thumbup: |

Chris, if you can find some and have some way of melting them down, pre-1919 coins are sterling silver. 1919 to 1947 were about 50%. How about finding a friendly working jeweller or silversmith who will submit the part for you, or are you intent on making up a stamp to impress your own initials/logo as part of the hallmark? Andy |

Andy, yes I realise I`m being a bit of a arse, but it is always something I`ve fancied doing; I want my own sponsers stamp! To be honest, it is for that reason I`m even considering it, otherwise I wouldn`t bother. Equally, I`d like to make the part myself or at least under instruction. Thanks for the info about the coins. I do believe I actually could melt them but I don`t have a press mill to flatten it neatly back down to shape. Maybe hammering would work!? PTsideshow - there is a video on youtube showing someone making a bezel for around a ring stone as you mentioned. The idea about the copper is a good one and cheap to just see if I`ll like the design. Thanks for all the suggestions and info...any more welcome. I`m actually leaning towards really wanting this to happen and think it possibly could. Mind you, I`d probably have to wait a few months for my birthday to register with the Assay Hall and afford the silver! |
