Going to machining class is downright painful

My sister boyfriend (about 38years old) sends his BICYCLE to the shop to have the chain oiled & the brakes adjusted... However, I should point out that he's a tax auditor... My sis showed him how to change the wheel on his car after he got a flat.. he hasn't driven since...

I know your pain. A couple years ago I was in my machining class making a drill bit diameter gauge. Over half the kids (engineering majors) didn't know how to chuck up a bit or keep the work piece from spinning around on the drill press.

How many tried to use their hands to stop the piece from spinning?

We had a guy at work running a drill press with a counterbore in it. For those that don't know, a counterbore is a multi-fluted cutter with a pilot on the end. Anyways, he was wearing glove and counterboring a piece of sheetmetal with no vise. Both a huge, huge no-no. Bottom line....it grabbed, grabbed his glove, and PULLED his thumb completely off. Now the other thing that made this happen, other than stupitidy, is that the drill press was gear driven insted of belt driven. There is not much stopping a gear driven press whereas a belt does slip after so much resistance. It may or may not have saved his thumb. But he did get it sewed back on and does have limited use of it. And we had new safety rules laid down too. No more gloves on a drill press, don't leave chuck keys in the press and turn them on, and if something grabs, hit the off button. Some of the drill presses used to have the chuck keys chained to the press so they would not come up missing. Not really surprising as to how many times the press was turned on with the chuck key left in the chuck.

Best thng I seen was a guy trying to drill a hole with the spindle turning backwards! Obviously didn't get very far.

Our machines were all set up in a row and I was squaring up some blocks. I don't remember the exact numbers, but cranked up the depth of cut and the feed rate. Turned on the automatic feed and stepped back to watch the chips fly. The looks on everyones face was hilarious. Nothing like blue hot chips flying off!

The biggest problem I see is that there's too much of an emphasis put on CNC machines too quickly. I have alot more respect for the tool & die makers that can make tools using pencil, paper, calculator and manual machines than I have for "tool & die makers" that shortly after they get ther ticket jump onto Mastercam and CNC machines never to touch a manual machine again.

I've been reading through this thread and I find it very interesting as I am an automotive instructor at a High school. I can't say much about the change in the students from 20 or 30 years ago to now, because I am only 26 myself(I'm only in my second year of teaching). But I do know that many of my students have no desire or motivation to do much of anything in my class. I can assure everyone that I spend plenty of time going over safety and tool usage. When half the class can't tell the difference between a 1/4, 3/8 and 1/2 ratchet by looking at it after being shown almost everyday for a week, you can't exactly get a lot of content taught that we are supposed to be teaching. My class becomes a dumping ground for students to be put in that are always in trouble in other classes or simply arent enough other classes or teachersto handle the number of students in our school, so they stick them in my class. We are a NATEF(affilliated with ASE) certified school, and that specifies that we only have a max of 16 students in our Auto 1 class. The administration put 26 in my auto 1 class this year. I've battled with them and got the numbers down to 22 but its still too many. Bear in mind that our shop only has 1 lift and room for 1 or 2 more cars on the floor. I've only been teaching 2 years and already I'm discouraged. My students have no motivation, I have too many students/not big enough of a shop, and to top it off I dont get payed anything. I can't even afford to rent a nice house, much less build one. Thats how I found this forum, searching for ways to build a cheap garage apartment myself. I could go to work in a dealership as a tech and make much more than I make now. If yall want to do something to improve vocational education, vote for politicians that support all education, not just vocational. By the way the Bush administration has tried to cut out the Carl D. Perkins act every year its been up for renewal, which is the act that provides all federal funding for vocational education. Any high school automotive program that is NATEF certified(most are) are required to have an advisory council that is made up of local industry members. If you are in the industry get involved, if not encourage industry members that you know to get involved. See if you can get your company to donate an old lift to a high school. Dealership owners and such that have money are able to put great pressure onto school administration to make improvements. I know its helping me get a fenced in area outside my shop for vehicle storage, I know its not much but it helps.

I thought in 2006 Bush re-newed the Carl Perkins Act and signed it back into commision?

that's true, clinton actually slashed it three times saying that tech was the future of America.I guess he thought even cars would just fix themselves?

I took auto mechanics when I was in high school and had a great time. The first two years we had an old school teacher and he ran the class like an auto repair shop. We worked on cars brought in off the street for service. We fixed cars with parts provided by the owner and didn't charge for labor.

The last two years wasnt as fun. The old teacher retired and the new teacher was younger and tired to teach more from books and the classroom than hands on in the shop. All in all it was a great experience.

My 11yo daughter can tell you the size of a nut or bolt to within 1/8in from 20feet away. She's getting better, but she can't work out how the hell I can do the same thing to the 1/16th (or to the mm on metric stuff).

If you ask him to hand you a philips screwdriver he has a 50% chance of getting it right... If you ask for a "#2 philips" (assuming he gets the philips part correct) he will hand you the 2nd one he see's...
He doesn't even understand the meaning of "righty tighty lefty loosey". It's been explained to him a few times, he just can't grasp it at all...

Those people both make me happy and sad.

Happy since I can make money doing simple things for them aka job security

Sad that anyone can honestly care that little about basic things. People wonder why society doesn't change quickly when there are people who don't even care to figure out the basics.
