That's why carbide comes into the shop with an MSDS.
What lathe?

But does it come into Brad's shop? 
:msp_mellow: :msp_confused:
Seriously.. sure, it's well known in industry, but how many newbie home shops understand the follies of grinding of carbide?

You are correct. I would not have known.

I do have a diamond grinding wheel, but have never used it. I've never used any of the carbide chains.

As we're on the subject of safety...Brad I believe I've seen a few vids of you running saws with no eye protection. I hope you will not even turn the power on for the lathe without eye protection. Suffice it to say that any lathe is capable of producing projectiles that will take your vision from you.

Guilty as charged. I'm kinda bad for that. But that is solid advice. I should know better seeing what I do for a living. I've had a piece of metal embedded in my eye before, and I can honestly say its not a pleasant experience. Took two days to deal with it, first day they had to extract the metal from my eye, go home with a patch, second day had to spend hours waiting at the eye specialist to remove the "rust ring" from my eye, very unpleasant to have someone grinding on your eye, and I'm not even kidding, they use a small burr grinder and grind the stuff out of your eye.

I know Will, I've been there. I had a piece of cast iron embedded in my cornea. It got there even though I was wearing safety glasses while I was cutting it. Some of the most excruciating pain I have ever dealt with. Having someone use a porting tool on your eyeball is not so much fun.

Yup, I was even wearing eye protection at the time it happened to me, just goes to show you your never 100% safe.

years ago, Got a metal speck in one eye, while bandsawing something.
Was wearing basic safety glasses, but sometimes it still finds a way in.
And yeah that DR picking it out (little ting, ting, ting noises coming through sinuses to ears) and then bout 45 mins later sanding it smooth with a glorified "dremal"
does sorta pucker ya backside.

I don't care to repeat the experience anytime soon.

Remember to tell your doctor (put in your records) that your are machining. If you need a cat scan you'll first need any x-ray of your eyes. Unknown (yep, many you do not even feel) tiny pieces of embedded metal tear through the eyes when exposed to the strong magnetic fields of the scanner. Hey... maybe I should get a cat scan to rip all the metal out of my hands!
Both the lathe and mill are are miserable for throwing chips everywhere. In the past two days I've removed about 120 cubic inches of steel from a part I'm making. Everything within 5 feet is inches deep in nasty blue curled razor sharp chips that were HOT while flying. Only a dozen or so got me on my bare arms
I've had some nice "spring" like burns from my lathe curly chips - short sections say 1 inch tightly spiraled that slam on to your skin and STICK . I hate that especially when it's on your neck. So... if that hot spring hits your eye, you'll lose it.
Glasses work, but for some work a full industrial face mask (the round flip-up version) works better.

Blue chips, up your shirt sleeve, while holding the feed lever, on a finish cut, near the face you are rapidly approaching..........

Like this. Happened last week. I was more than 15' away from the cutter, but it was over 7' up on a part. Chip had plenty of time to cool before it got to me, and it still got me good. Imagine if it was your eye.

Off the new boring mill?

Exactly. What is amazing is when you are close enough to the cutting that the chips bounce off of you instead of sticking, but you can still smell the singed flesh from the microsecond of contact.
Yeah. We have a big G & L. Well not REAL big. But poured over 80 yards of concrete over unknown tons of rebar when we put it in.
Hogging on the W&S 3A.......melting holes in jackets, shoelaces,hair, lunch cooler, phone......you learn!
And the blue chips steaming and piling inches deep and have enough coolant in the chip pan too keep the steam down.

We got floor mats made for a weld shop. Put them over regular mats. No more burnt holes in mats and easy on the feet!!
I remember visiting an equipment fair in Hannover a few years back. A dutch manuafacterer was demonstrating a multiple boring unit for drilling holes in I beams, with the security doors open. As buystanders watched the demo, including myself, something hit me straight on the nose. Turned out ot be a hot sharp chip that left me with a bleeding wound. Machine was shut down immediately and the dutch owner begged me not to report it to fair security for the risk of getting banned from the fair. Can't imagine if that chip had hit somebody in the eye....
