nonjic Posted May 26, 2010 Share Posted May 26, 2010 This is my first try at anything 'crafty' and im pretty pleased with the results. Gonna try a few different things jewellery wise (stainless 'mascus, mokume , siversmithing etc) but weve all got ot start somewhere ! turned it on a rather large lathe Its 15n20 / 20c & pure nickel, straight laminate (nothing fancy, I was just testing the process!), so its gonna need plating. If I get a couple more done I will have a looksy into hard chrome plating (know an industrial shop that will sort it for me!) all feedback appreciated!

thecelticforge Posted May 27, 2010 Share Posted May 27, 2010 Brilliant! I would love to know the process you used to get the ring shape. It has to be better than what I do. Quote Link to comment Share on other sites More sharing options...
John B Posted May 27, 2010 Share Posted May 27, 2010 John N If you are going to chrome plate, aren't you going to lose the pattern to a degree? Quote Link to comment Share on other sites More sharing options...
nonjic Posted May 27, 2010 Author Share Posted May 27, 2010 I turned this on a lathe from a piece of soild bar, John, Im 99% sure that hard chrome plate is a clear coating. Im going to make a couple more, and experiment with depth of etch, and leaving more of the black on the 20c after etch etc(this one is buffed shiny) Ill do a few to make it worth taking them to the platers and see what they come out like. I dont have a much time investment in them so just keep playing untill I get nice results I really need to start welding stainless! Quote Link to comment Share on other sites More sharing options...
Mainely,Bob Posted May 27, 2010 Share Posted May 27, 2010 John, Im 99% sure that hard chrome plate is a clear coating. Are you sure you don`t have hard chrome confused with hard anodizing? Hard anodizing is in fact a clear coating. The hard chrome I`ve seen on hydraulic cylinders and other things was a shiny metal skin much the same as the chrome plating on a car or motorcycle only much more durable.

nonjic Posted May 27, 2010 Author Share Posted May 27, 2010 Hmmm, Ill have to do some reading, but I thought the chrome was clear, but for decorative applications it was applied over the top of a previously applied electro deposited 'shiny' base like nickel? and for applications like hydraulic cylider rods it just looked metal coloured, coz it was applied over a ground rod. I could have looked this up in the time its taken me to type this , research tomorrow! Quote Link to comment Share on other sites More sharing options...

I could have looked this up in the time its taken me to type this , research tomorrow! What you may be thinking of is the standard process of properly chroming steel,what some call "triple plate". The part is first plated with copper because copper bonds to steel better than straight chrome does then it`s plated with nickel because chrome will not bond to copper as well as it does nickel then the chrome is the last to be plated on.That`s the short version of what the hotrodders and MC boys pay big $ for. Each is an actual layer of that particular type of metal and as such it is opaque. I have never heard of an electro-plated metal you could see through(doesn`t mean it doesn`t exist,just means I haven`t heard of it). Quote Link to comment Share on other sites More sharing options...
nonjic Posted May 27, 2010 Author Share Posted May 27, 2010 Thanks bob! Ive just had another read up, and the chrome layer is a silver grey metallic colour, what youve written makes prefect sense now. I was under the impression that a very thin layer of chrome would still allow the base metal 'colours' to show through. :rolleyes: Quote Link to comment Share on other sites More sharing options...
Bentiron1946 Posted May 28, 2010 Share Posted May 28, 2010 Perhaps you're thinking rhodium plating that they put on top of gold and other precious metals to protect them from tarnish and dulling. :blink: Quote Link to comment Share on other sites More sharing options...
nonjic Posted May 31, 2010 Author Share Posted May 31, 2010 Had a play with some 925 sterling silver today, pleased with the result! The steel is another section from the bar I made the first one from,. Quote Link to comment Share on other sites More sharing options...
tzonoqua Posted May 31, 2010 Share Posted May 31, 2010 These are very, very nice!!!! Wish I could do that, but I've never even attempted pattern welding!! On a side note, you are probably aware (as you mentioned plating/coating the nickel version) but I'll mention it as others may not be, but jewellery containing nickel has some pretty precise regulations in the uk (and probably best avoided in anything that will have contact with skin). Again, nice work! Quote Link to comment Share on other sites More sharing options...
Sask Mark Posted June 1, 2010 Share Posted June 1, 2010 I would wear those and I'm not much of a jewelry wearer. I think they're great. Quote Link to comment Share on other sites More sharing options...
beth Posted June 1, 2010 Share Posted June 1, 2010 yeah they are wicked john! like colleen said some people can react to nickel and the pattern welding of any sort would be a prob to hall mark but i havent let that stop me mixing silver and gold for jewellery. makes it more magic i reckon! i have never attempted pattern welding either but would love to one day - they look great. are you going to try forging some or is it specifically the machined style you like? the silver one looks beautiful.

nonjic Posted June 2, 2010 Author Share Posted June 2, 2010 Thanks for the nice words! Beth, I did forge the steel before it went in the lathe, so it almost counts! Quote Link to comment Share on other sites More sharing options...
beth Posted June 2, 2010 Share Posted June 2, 2010 john, i meant forge the ring shape - i know youre more than capable! just wondered if you preferred the lathe look ;) Quote Link to comment Share on other sites More sharing options...
Bentiron1946 Posted June 4, 2010 Share Posted June 4, 2010 That nickle in jewelry is sure a problem, I made some "German Silver" rings in the seventies and a woman bought a half dozen of them and then her and her two daughters fingers all broke out something fierce with this awful rash that looked like blisters. She thought that German Silver was like sterling silver, no not so! Got to watch what you put out there for sale or as gifts these day, someone will sue your butt blind. Nice looking rings whatever they are made from. B) Quote Link to comment Share on other sites More sharing options...
