I would think that one good whack & a carbide ring would be in pieces.
Given the kind of work you do, a whack is inevitable. Do they tell you
what grade of carbide? Some are more impact resistant than others.
Carbide will also be heavy. I think you can achieve a similar look with
hematite. It may be no more rugged, but I suspect it's cheaper, so you
could buy spares...

I have a tungsten carbide wedding ring, and it is totally great. I do
not hit it with hammers or anything, and it holds up just fine, does
not get scratched etc.

Note that cheap rings are made with cobalt binder (like end mills) and
the better ones are made with nickel binder, which is better in
jewelry applications.

Having had an earring pulled out I'm going to say tattooed ring if
it's forever. Titanium probably sounds more high tech than carbide.
Looks like alloy determines hardness.

I kind of view rings and other jewelery as an opportunity for power
equipment to rip and/or burn my fingers off. The only reason that I wear
my wedding band when machining is because it won't come off without
cutting something up (yes, kids, your joints _do_ swell up as you age!).

My hair was down to my waist when I was in college -- once I got out and
had time for machining and leaning over running engines again, my hair
got short, quick.

And if you play with high-voltage electrical devices, they're great

I lasted about three months wearing my wedding ring. My wife
understands...

As for titanium rings, Ok. They're light, moderately
scratch-resistant, and, if they're the right alloy, they'll stay
bright.

I can't imagine why one would want a tungsten-carbide wedding band,
but whatever turns you on. If you could use it for striking a fire,
scaling a fish, or something else useful, I'd consider it. d8-)

They are indicating that the good ones are alloyed with nickle rather
than cobalt and that makes em tougher.

Maybe. It depends on the grade of tungsten carbide with nickel binder.
Some are tougher than cobalt-bound, others are not.

The reason to use nickel is that it's resistant to acidic corrosion
from sweat. Cobalt will corrode in acidic environments.

It may be, but it's unlikely, that jewelry companies select a
particularly tough grade. Their main issues are related to brightness.

As a maker of titanium jewellery, including finger rings,
This metal in is pure form is ductile, so it will bend if you get it

Tungsten carbide is much harder but not as durable as titanium, tho it

Nickel is now banned in jewellery here in the Uk as well as throughout

Tungsten isnt as durable? Everything Ive read so far says that the

effect even the nickle sensitive.

Are we sure it's really tungsten carbide as in carbide inserts? Good old
AISI T1 tool steel (what we call 18-4-1 in the UK) is 18% tungsten, and
the hot hardness comes from the fact that there's a lot of tungsten
carbide in there. But I bet it makes a pretty durable ring.

Unless it's a pinkie ring, I don't think that's a problem, but iron

stainless steel rings these days.

This was why *I* was thinking that the carbide would be
*preferred*. If something happens to pinch the finger and the ring
between two hard points, the titanium could crush onto the finger and be
pretty much unremovable until you removed the finger. The carbide would
break, so removing it is automatic.

For the usual gold alloy rings, there are special pliers which
have a split jaw which hooks under the ring, and a key turning a small
circular saw blade in the other jaw to cut through it and allow it to be
removed. Given how titanium work hardens, I don't think that would
work.

The engineers iron ring has a fair amount of tradition and ceremony
involved with it. Up until the mid seventies, it was made from a beam from
the original Quebec Bridge. They were hand hammered and left a brown oxide
stain on your finger. I lost my first one which was the original wrought
iron. As I was living in Australia by then, I got a friend who was also an
engineer to pick one up for me and bring it over next time he came here. By
this time they were making them of stainless.He picked one big enough to
wear on my thumb! I went to a number of jewlers to get it made smaller, but
none would touch the job. I took it into the workshop at the plant where I
was engineerin manager, and asked my best tradesman to cut it and TIG it up.
He did an excellant job and I've worn it for about the last 20 years. The
weld is only visible from the inside but as I can no longer take it off, it
doesn't matter.

How about getting a ring wire-edm-cut from a large
tungsten-carbine mill or lathe tool bit.. With such
a stiff material, I'd make it a "C" shaped, with a notch
at center of C, so if something horrible happens, it
might break before your finger..

Of course, requires a cheap edm place to be worth it..
With a fancy wire-edm, the outside could have almost
any 3d shape - like one side rectangular- and other
sine-wave or..

As metal workers, there are a no of symbols, that represent us and our
tools.
the first is the hammer,
the second is fire
the 3rd is the hand
the 4 th is the eye
and the last is the heart.
bring all these together and youve the basis of creative spirit you need
to make something original.
So,
to implement these symbols, the easiest way is to take some small cold
chisels both round and rectangular ends, say 4in long
anneal them in a propane flame or cutting torch, whatever you might
have handy,
hold them in a vice cutting end up
get some needle files a junior hack saw and some small drills
and file/cut up the designs you think represent the above.
Harden and temper to a straw colour.
The easiest one to start with isthe eye
file the outside shape first, then drill a small depression in the middle.
Try it out as you go on lead.
Then cut a strip of copper say 1/4in wide, by 3in long or even lead to
start with , easiest to experiment with, then hammer the designs into
the metal.
Whwn youve done a few youll see what im getting at.
THEN,
get some titanium sheet, say 30/40,000 tho in thick, cut to width and
length, file up to round off all edges, more on finishing another
time, then hammer in the design sequence you fancy.
whne youve done that, dress the ring strip around to fit the ring size
you have in mind.
then finish it with polishing wheels etc.
you can hold the ring against the polishing wheels with the ring on a
piece of tapered broom handle.
i made a set of 50 of these punches with all sorts of designs, used them
on hundreds of rings and bracelet sets

As a maker of titanium jewellery, including finger rings,
This metal in is pure form is ductile, so it will bend if you get it
caught in a door or vice.
Tungsten carbide is much harder but not as durable as titanium, tho
it will probably hold its polish longer.
Nickel is now banned in jewellery here in the Uk as well as throughout
Europe on account of the fact it causes alergy problems.
If you can get say a bit of titanium bar, why not turn one up
yourself? If it comes out ok youl find that other folk will want one
of your rings too!!

Ted.
In Dorset
in UK.

Thats what I was considering, turning out a titanium ring myself.

Tungsten isnt as durable? Everything Ive read so far says that the
nickle alloy for some reason, when alloyed with tungsten, doesnt
effect even the nickle sensitive.

????

I thought about an iron ring, then did a bit of research and found its
status with Engineers..so backed away quickly from that idea.

I do metalworking, so was thinking about something unusual as a symbol
of the craft/hobby.

Would you have any other suggestions?

How about getting a ring wire-edm-cut from a large
tungsten-carbine mill or lathe tool bit.. With such
a stiff material, I'd make it a "C" shaped, with a notch
at center of C, so if something horrible happens, it
might break before your finger..

Of course, requires a cheap edm place to be worth it..
With a fancy wire-edm, the outside could have almost
any 3d shape - like one side rectangular- and other
sine-wave or..

Kristian Ukkonen.

Not..not a bad idea. But most carbide endmills are pretty fragile...they
dont have nickle as an alloy, as I recall

Ill ponder on that one. I have access to large (busted) carbide endmills
occasionally and can come up with the stock.

Note from the discussion above that the suggestion is to carve a ring
out of a solid piece of carbide. I don't know how much diamond that
would take, but my guess is that it would make a down payment and a
few monthly payments on a nice new truck. g

Diamond is great for sharpening and honing carbide tools. Using it to
drill and bore a hole for your finger, and to shape the outside of a
part, sounds a little over the top.

FWIW, silicon carbide will grind carbide, too. I don't know if it
actually cuts the tungsten carbide itself, or strips it out of the
metal matrix. It uses up a lot of silicon carbide wheel life and it
doesn't cut the tungsten carbide very cleanly.

But I don't think that's practical, either.

EDM has been used for cutting tungsten carbide since the mid-'70s.
Some wirecut machines are optimized for it, but they're pretty slow.
Still, it does work, and it's used to make practically all of the
leadframe dies in existence, as well as dies for most small electronic
bits punched with carbide dies in high-speed presses.

Any way you do it, it would be exorbitantly expensive to carve a WC
ring out of the solid.

Around 5 mm3/min machining rate for tungsten carbine with wire-EDM..
If the ring is 5mm thick and the edm leaves 0.35mm cut, that would be
0.35mm * x * 5mm = 5 mm3/min - x = 2.8 mm/min
The slice of 5mm thick disk from the D30rod would take some time too.
15mm*15mm*pi*0.35mm /(5 mm3/min) = 49min (per cut, 2 cuts)
So it could be done in a day.. Couple of hours to get the disk,
a few hours to finish the ring. Not unreasonable at all.
The machine with X,Y,U,V could do a fancy outside shape.

Of course, that requires a friend with wEdm doing it for you..
The real hourly cost of wEdm is not THAT horrible if there is no
profit to be made for that day of machining (on sunday).

BTW: I recently picked a used wEdm from ebay.. Brother HS-100..
http://www.mh-erodiertechnik.com/pdf...s100/hs100.pdf
Nice little machine. Max. 100mm2/min for steel. I'll expect
to make first cuts this week.. Took a while to clean the damn
rusty water tank, citric acid worked wonders though. Already have
the DI water running and 0.25 brass wire running ok.. Need to read
the fine manual a bit more on the CNC programming still before
first cut. That's the only SMALL wEDM machine I've seen..

Uh, not to pick nits, but you probably mean mm2, not mm3. Wirecut
cutting rates are expressed in square units of measure.

At what, $50/hour? For a day's worth of EDMing? That's an expensive
ring. g

If you own the machine and don't care about the cost of it, you're
looking at around $6/hour for wire.


The machine with X,Y,U,V could do a fancy outside shape.

Sure, as long as it's a curved 2D shape.

Eh, in practical terms, that's a meaningless number. It depends on the
kerf. Researchers may care about it, but EDM *users* just want to know
the travel rate through different types and thicknesses of material,
in square inches per hour, square millimeters per minute, or
hectares-per-lifetime. g

You can get fancy, but it's always a line (wire) projected along a

high, and you get unwanted curved lines from wire drag...

Loverly. Greg Langenhorst of Mitsubishi EDM used to make some things
that looked impossible. Then I spent hours trying to photograph them
so someone could see how impossible they were. But it rarely came
across in a 2D photograph.
