My explosives minor (and certificate) has absolutely nothing in common with any other minor or my major. That's for the sheer enjoyment of blowing shit up and having that particular teacher.

What sparked my interest in a Materials minor was the Manufacturing Technology class. Then, I heard some girl talking about taking a glass blowing class. I though that'd be cool, but in the search for finding it, I saw Metals Casting. So, I chose that.

In other words, these are classes I want to (and do) take, but I might as well make them count for something, right?

I was gonna work at the foundry but just couldn't cope. Just as well, as I found it all to be a drag.

"[Machining] seriously takes absolutely no skill at all. It's so easy." said the guy with the popped collar standing next to me. Both labs, he's been the one who shuffles his feet the loudest (why do people do that on bare concrete?), doesn't wear the lab jacket, and is the only one in class who puts his safety glasses on the top of his head.

Week 3: I cast my little styrofoam shot glass. We set it up in the same cope/drag, with the green sand. We didn't jolt/squeeze it, though, but packed it in by hand. It's pretty rough, so I think I'm going to put it on the lathe on my own at home. Some other kid made a plum bob, someone made a cube () and I couldn't really tell what the other stuff was. I'll post some pictures (and a video) Friday.

so you've been in school for about 12 years is what you're trying to say

i don't think i ever took a class in college that required standing up. fyi, minors count for nothing outside college, not that it matters, its why i switched one to a dual major and only took history and political science classes for 2 straight years.

Warm rubber an lube are key. Taking the Tourance off is the easy part. The new Tourances are meaty and tough, again warm rubber.

rolla...i'm guessing you go to UMR/MS&T. There's a wire EDM somewhere on campus that some of the design team students have access to for cutting their parts. when i took ME153, some had access to the EDM so they made cool things like their greek frat letters. for designing, i think you just use autocad. probably won't have access unless you're on a team (join baja ). just cast the entire block and take it to a recycling center for some cash.

is randall teaching the class?

Pretty much. Started off half time at the community college.

I can see the light at the end of the tunnel, though.

My math minor might not count for anything. But, my explosives minor and what little I have of my materials minor so far, have actually both led to job leads.

I will end up machining it. I suppose I could have used a soldering gun or something on the original styrofoam mold, but I didn't have any on hand.

Finish up with a boring bar set-up to clean up. Hand manipulation of the mill table will be needed.

Don't forget to break all edges and de-burr as required and use all appropriate PPE.

I made one of those several years ago. I bead blasted the finished product so the tool marks are harder to see and it really does mess with people. I've had all kinds of excuses thrown at me like "you heated up the outside so you could stretch it enough to get the little cube inside"

Your dimensions are a little off. The diameter of the hole you bore needs to be slightly less than the distance between two diagonally opposite corners of a face of the captured cube. When you bore .500" deep into a cube with an edge length of 2 inches, the diameter of your hole needs to be around 1.4 inches, depending on how much material you want to leave to hold the captured cube.

The dimensions of the Machinist's cube below are:

Edge length 2"
Hole diameter 1: 1.394" bored .500" deep
Hole diameter 2: .687" bored .250" deep
