These are c-1 carbide blanks. It is the same tungsten carbide used to make solid carbide end mills and similar. The reference cube is 1".

How would you use these pieces of carbide?

Hello Evan
The triangle could possibly be made into a hardness tester. Carbide dust is pretty nasty stuff to breath. I'm thinking that only diamond or those green wheels will cut it.

Carve out a small, altar-like, rock grotto somewhere on your property. Arrange
the pieces as shown in the grotto, then cover with volcanic ash and allow it to
concretize in the rain.

Go to bed in the firm knowledge that, eons from now, you'll be the subject of
endless speculation at an international conference of archaeologists.

a screw machine shop might use them, they buy a dovetailed 4140 block, machine it to hold the carbide,silver solder the carbide to it and then wire edm them to make roughers and shave form tools.

I have made alot of them.(the machine and silver soldering part not the edm)

the tool and die guy at the screw machine shop would take round carbide blanks and make very cool multi diameter form spade drills, totaly amazing.

You could send those pieces of carbide to me and I would give them a good home

That pyramid shaped one. If you had a bunch spread them inside youre front house entrance so burglars will step on them. AH well maybe just toss em out cant keep everything even though its nice too keep everything.

I like mklotz's suggestion the best.

I'd shave the top of my head and epoxy the pyramid to it. The density and molecular structure of the carbide will channel cosmic rays from the chronosynclastic infundibulum into your medulla oblongata better than the aluminum pyramids most folks use...
Trust me on this one.

C-1 means woodworking or wear pads,or in my case bandsaw guides that never wear or need adjusting.

Or if you drill a hole in the corner the pyramid would make an excellent nose ring http://bbs.homeshopmachinist.net//biggrin.gif

It may be too late to dismantle them ... you've already summoned a distant alien race which is at this very moment, speeding to your destination, homing in on terrestrial microwave broadcasts re-shaped by the double carbide pi network http://bbs.homeshopmachinist.net//eek.gif http://bbs.homeshopmachinist.net//eek.gif

How about ultra hard wear pads to protect something else ... although they may be a bit small for anything of that sort.

I am not exactly sure what I would do wih them, or the cube of the pyramid, but it sure would be a nice problem to have.

I have a bunch of misc carbide also, probably a couple pounds or so. A shoert stick of reounded triangle, right for slicing off cutters, a couple odd form cutters an inch or so long, a bunch of pieces to be held in some unnameable holder, or brazed onto things....

Sounds like they aren't very useful, and nobody recycles the stuff (unless you have drums of it).

Looks like its going out to annoy the landfill diggers in a hundred years or so.

The pyramid shape isn't carbide fellows.

Evan,
It is very hard to tell what they could be used for without a closer examination. Send me one for my professional opinion. http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

Hey Evan I'd use them to make brazed carbide lathe toolbits, a carbide tipped scriber or some other layout tools. BTW I'm going to be driving through Williams Lake in a few days if ya don't want em.

Tryp,

Stop by my shop on the way and I'll give you one. I would tell you to stop at my wife's shop but she will be attending the Saw Filers convention later this week in Prince George. If you are in PG on Thursday 6:00 to 10:00 pm or Friday 3:00 to 10:00 pm you should drop in and see her. Admission is free, just tell the person at the door you are visiting Janet (my wife) at the L&S Industries booth. The convention is at the civic center. You might be able to pick up some freebees from some of the exhibitors.

Evans carbide is excellent stuff. I modified a tool holder that I never use (it came with my lathe) to hold a piece.

From the Morse Cutting Tools site about C-1 carbide:


<font face="Verdana, Arial" size="2">Heavy-duty roughing to extremely heavy-duty roughing of cast irons, 200 and 300 series stainless steels, a broad variety of high temperatures, high strength alloys. Intended for severe applications at relatively low cutting speed.</font>

Ya,at HSS speeds and feeds and when they say rough,that applies to the finish as well.About the same as you get dragging it down the road behind a car.

It will take lots of impact thou.
