More from Kaltezar
It's taken me quite some time to get these items finished.
The first set was over 22 hours of work, and when sent to the US to their final destination, the items were stolen and only an empty package showed up. So this is the second and hopefully the last set that will be made.
What you see before you are two 'coins' which I made from a large blank of 30mm Stainless Steel round, 316 grade. This means it will never corrode. First the blank was lathed to the 28mm diameter they are now, then the 6 half radiuses were CNC'ed vertically from the face down. Next the pattern was etched into the surface using a 0.4mm bullnose carbide cutter turning at 5,000 RPM and only cutting 1mm per minute. (yes that's very small, very fast, and very slow) Finally after the pattern was cut in, the blank was put back in the lathe to very carefully and slowly part off the thin coin of 1.5mm from the larger blank to arrive at what you see me holding in my hand.
Between each step roughly 1 hour of sanding and polishing was done to every available surface, so when the final piece was finished, each surface would be mirror bright. Because these pieces are stainless steel, and not silver - their ability to resist abrasion and scratches is much better and they will not tarnish easily.
The two holes at the top were put there to loop a chain through. The backs which are not seen, have a basic machine finish and will likely get some kind of engraving later down the road.
(Yes, these were made by request, and no I will not be doing anymore as I'm no longer in possession of the CNC equipment that I used to do this work.)

Thanke Rara, You have no idea how enraged I was when the origionals were nabbed. I wish I could post a picture of what the origionals looked like with this, but they were pretty much the same, but didn't look nearly as polished or finished. In a way it was good the first set was nabbed, because the second set turned out so much better.
hrrrm you know, you can get simple components like that factory made and shipped to you by this thing called E machine shop. if you order like 100 of them and have them made in a certain way, ie: machine stamped. it could be as cheap as maybe $5 a peice... assuming they're not made of silver or something.
can't immagine it's too hard to make them by hand, except the engraving part.
I suppose it can be done using a softer metal. I've worked with stainless and it's tough as nails to cut and file and it was only sheet stainless too.
Orrrrr... if you're the blacksmith type, you can heat the metal up till it's red hot and then carefully try and engrave it.

Argh, helps if I hit the right reply button...
Sadly, whenever I build something, the first concern is longevity. This is why 316 was used, it's medical grade stainless and other then titanium, platinum and some other virgin metals, is exceptionally difficult to corrode.
So, This is why highspeed carbide cutters on .001 precision CNC machines are required to effectively work this metal. of course I could make these using substandard materials which are easier to work, but sadly my work ethic prevents that :}

Stainless by it's nature resists acid, for example the compound used to clean a stainless steel weld is called 'pickling gel' which is basically Hydrofoloric acid in a thick suspension. Very nasty stuff and yet does nothing to the base metal.
The reason I went for engraving was because it will last for a very, very long time, through repeted polishings and cleanings.

Believe it or not i once had the same thing happen to me... it kinda puts me off on international orders, you know for a fact they will be "opened and examined" and the more hands something moves through, the easier it is for someone to just say "dont look at me, was empty when it got here"
Was kinda worried thats what happened with my goggles... but i was determined i wasnt going to ask the maker about it cause i didnt want to sound impatient...as it turns out he sent me message he got backlogged and was really nice, and apologetic about the whole thing, i love dealing with nice people, it makes my whole day...

Right-O! Lemme know when you've got the equipment ready an put me in for- les'see 30 mm...times 48 up and down and 48 round and say 18 times twenty times two...cary the square root of -9 and...Yeah better make it an even 6000 pieces to make a short sleeved scale jerkin for me...so at 22 hours for each two with speed/skill increases over time...say moritized(SP?) down to 8.733+/- hours each...so half a year to turn out that many...and then twenty years for me to sew it together...yeah sounds like a deal *Skirk!*
Damned cool work dude!
