I machined my first object today :)

For my engineering class for our first machining project we are making a C clamp out of 6061 aluminum. Steel eventually but aluminum to start. ANd for the first time i machined something entirely from scratch, the screw for the clamp. From a 1/2 piece of stock aluminum i made the screw . Using the lathe i cut shaved off the shaft to .375" leaving one 1/2 " section where it is knurled to just under .5". I will get pictures of hte final project as soon as i mill out the body.

I need a good c-clamp for one of my designs at work. Maybe I'll sub you in. The guys in our shop are taking forever to build my prototypes.

Well i know the one we are making is 3 inches long and 2 inches tall i believe. 1 inch thick. A real basic design, but it familiarizes us with the lathe+bridgeport milling machine

That sounds like fun.
Almost a shame I'm not in high school so I could do a class like that...

man, we don't have any shop classes at my school.

This sucks. No car shop, wood working, metal working, etc.

yeah, pretty much all we have at school is academic classes, I take weight training all the time so atleast I get out of my seat and get to lift a little.

but all we have are academics, unless you count stuff like ceramics and art shop classess.

Here at BGSU, I have to machine a servo valve for a power steering pump. I have already casted an angle plate out of 6061 T6 aluminum, lathed two arbors, one out of aluminum and one steel, built up a drum sander table(machined a perfect 6" square, drilled holes and tapped them) and brazed/MIG/stick welded. Machineing rocks, I started with it in high school where we made our own lathe cutters, made a center punch and a drive punch, a C-clamp, and heat treated the punches. Someday I will be teaching this stuff, and that will be a glorious day!!

Edit: Its a "part" not an "object" FYI

In my Machining carrer class last year during my first year in the class, we made c-clamps out of steel. I also made a set of Aluminum pegs for a bike, the pegs are ok but don't slide rails to good, but there light as hell. This year the whole class worked on a mold for a guy who has a pattent on some Hair dye brush design, I made the handles for the sides of the mold, they were made from some round 606 aluminum and there about 1inch in diameter, and about 9 inches long, and knurled. I also did some bench work on the mold to take the mill marks out of it. Right now i am currently working with 3 people in my class and we are making some Customized Liscnce plate covers out of aluminum, and were are selling them as a fun raiser.

Phantom, what degree are you going for? I somehow thought you were doing bachelors in engineering, but it sounds like you're doing a more hands-on classwork than engineers typically have. Just curious.

Glad you're liking your classes. That's a good sign you're in the right program.

my cat pressed enter before i finished that post.
Im only in highschool, but there are engineering classes you can take, its a 2.5 year program which i forgot but your eligable for college credit if you pass various stuff. Im not sure what i want to do specifically but i know this course is going to steer me in the right direction since what i want to do is something related to these machines. Lets just say, its the only class im actually motivated to come in after school voluntarily for.

You do know knurling makes the stock larger, right?
