Makes me nervous.

Really. Do you know the end use of the parts you make?

Yes I do.

The company I work for is a Copper Refinery and I only make repair parts for the company. So I get to see the parts that I make in use and if I have any questions or ideas on how to make it better I can go to where the piece of equipment is at and inspect it for myself.

Cool. I have always been impressed with the machine shops when touring decommisioned Navy vessels. The Lexington at Corpus Christi just impresses the heck out of me. I'm a kid again when I get "on board". Battleship Texas is real nice but the carrier is a wonder.

Did I just stray off topic? LOL

Understandable

I've only been caught up once. Had heard horror stories of it but had never seen it or had it get anywhere close to happening. I was using some sandpaper, 2 inch wide by 5 foot long, to polish a shaft up when the sandpaper grabbed. It wrapped around the shaft and pulled me into it before I even knew anything had happened. Pulled my arm around and actually made me punch myself in the face as it drew me closer. I couldn't reach the machine handle to turn it off and just about the time someone reached for it the sand paper ripped and let me go. Dislocated my right shoulder and bruised the side of my face with minor scratches on hand and arm from the sand paper. I was lucky. Needless to say I don't do it like that anymore. I use small pieces that will not wrap all the way around the shaft and only use a couple of fingers to hold it. Or I use a pneumatic belt sander.

Blink of an eye

It will happen in a blink of an eye. A guy in a shop i ues to work in left the "T" handle in the chuck and lost a finger. due to the on lever being hit and the chuck rotateing in reverse catching his finger between the chuck and the way. In another shop a guy was power tapping a large tap and got caught with the tap handle. Luckly I still have all my parts in tact after being in the trade for as long as I have. Thank God.

I have only been in the business for going on 8 years now. Made it 3 years without so much as even a cut. Then I started getting a bit too comfortable and that is when the above happened. I wasn't even looking at the part, I was talking to someone that was beside me. Needless to say it took the "comfort" away and gave me respect for the machines. We did almost have a Thandle issue. Guy left it in the chuck and turned the machine on. 612 RPM the Thandle flew all the way across the the shop and stuck threw the overhead door. I didn't work around him much after that.

gona quote you here trev..

way past the sort of thing that makes my palms sweat.. this is one of the factors in aging im not sure i like.. remember Pop talking about things "getting" to him more.. and yep it just sorta creeps up on you.. one moment your blasting along in the fast lane, and next thing you know your over on the far right side driving the speed limit, the same thing goes to the "what can happen" thing.. anyway, laughed at the punched myself in the face and didn't with the dislocated shoulder.

Got a question T.. whats the story with not having lubrication on the part, or is that something im not seeing.. i always thought that was a big part of machining, are you controling heat another way or what sir...

The coolant should be on but the part having the notches cut it in makes the coolant fly all over the place so I have chosen not to use coolant. For as little machining as I have to do on this part the heat doesn't affect the material. I have to face a little over a half inch off of that part and I can actually take the part out by bare hand after this process because it is staying cool enough. The insert could use some coolant to help it not wear but with the heavy interrupted cut I am taking the insert is chipping the edge before it goes dull so the coolant wouldn't help that much either. Now when I was first turning the part and in the milling part I was flooding it with coolant, even when I drill it I flood it with coolant. Cutting oil when tapping the part. But good catch there. Today I did catch myself today spraying a little bit of Aerokroil (penetrating oil/rust preventer) on it to help lube the tip of the insert and get a better finish. Not much at all, basically just push the nozzle and then release as quick as possible was enough for each pass.

trev..

I figured there was a good reason and of course there is.. for what it's worth (nada) i've always felt the sort of thing that you do is art..taking a block of steel and making something out of it that depending on the item could be around for the rest of time.. what your doing and block laying for some reason have always been facinating to me.. maybe cause my shop projects wound up being ash trays half the time.. lol.. anyway art. and i guessed there was a reason i didn't see coolant.. hey the aerokroil.. why didn't that come up in the lubrication thread.. the viscosity (damn sp check still hidding) should be right, and the penetrating rust preventer sounds good.. Daisy.. ya list'n out there..

Trev.. just sent a pm to Vaq... you guys are in the thick of it.. supposed to be T watch till 10 pm.. The front that came thru here heading towards you guys gave us a full foot of snow, so it's going to nasty when it gets to your area.. don't wind up in ok tonight..

I didn't even think about the aerokroil in the lubricant discussion. It does stick around a lot better than WD-40.

Thanks for the heads up on the storm. It looks like we will get something but the worst of all the storms are mid Oklahoma and up. I knew we had a chance of something but I'm used to the wind right now. We've had plenty of 40 mph+ days and nights lately. We had a hwy here blocked off 2-3 weeks ago due to dirt drifting across it. The ditches were approx. 3 foot deep and they are still perfectly flat with the road and field beside it. Completely filled all the ditches in at that area. They have been hauling the dirt out by truck and Loader ever since and probably still have another 4-6 weeks of it. If I remember I will try and get a pick of it tomorrow on my way home from work. Show you a pic where they are cleaning so you can see how deep the ditch was and how full of dirt it is not. Oh yeah the main part of the ditch where it is 3 foot deep is approx. 8 foot wide.

i've seen documentrys, and heard stories about ditches being filled in, but when you stop and think how many sq feet in a 3 foot by 8 foot...good grief.. and guessing had to be a few hundred feet long as well.. thats some serious overburden.. glad their getting the ditch cleaned out tho.. change the flood plane for everyone otherwise..

see ya all later.. ISD, Pard...ha ha ..as Daisy says you'ns have pms..
