I was kidding with the rinse and repeat. As far as crucibles go, I clean mine with a steel rod with a slightly pointy tip (sharpened on the belt grinder). Carefully remove the leftover metal in a scraping motion until it flakes away. Then I use a wire brush to clean the small pieces off the sides and even the surface of the crucible so it is clean for the next heat.
You might want to get a large spoon(18" handle, 3" cup) to scrape the inside of the crucible while it is still hot from pouring. Most of the metal will come off easily while it is still hot.
Off the floor simply describes how we work with our sand and molds. The "old" way is to have a pile of sand from which you shovel into your molding machines. The molds are laid out in rows on the floor and are then poured as the metal comes to temperature.
Most foundries in the US, and worldwide for that matter, use what is known as overhead sand. A system that is installed in a foundry that conditions and stores the sand. It uses conveyors to deliver the sand to the molding stations. These systems are now being used in conjunction with automatic molding machines from Disa, Sinto, or Hunter.
Here are some pics of my shop. The man molding is my dad and I am the one pouring. Those are tomahawks we make for reproduction.
Casting is as much an anchient art as it is a modern science. I cast brass (70 Cu, 30 Zn), bronze, iron, aluminum and all sorts of special alloys. My family's shop is one of the last in the country to work "off the floor" as it's known in the industry. I am an engineer at another foundry which is converting the last of its floor molding to automatic. Although its not the way they really did it back then, its still a dying art in this country. Other than material improvements, melting technology, not much has changed in several thousand years.
Make a mold, melt the metal, pour, rinse and repeat.
At my school my Physics 211 (Mechanics) professor adds a semgent to almost every leture called "Hollywood Physics."
It similar to the idea of the article. His aim is to bascially prove, and show why a particular stunt or action scene would work, or disprove the ones that would not work. He formulates some assumptions and then solves the problem with formulas we are using during that chapter. It's one of the more interesting parts of the physics lectures, that is, the ones I can crawl out of bed for. It sure beats massless pigs on a frictionless inclined plane.
Yep. We OS X users really like the OS X support...
Well, I can't say that I mind not having Napster, I'd rather support Apple with iTunes, which I already do.
The problem is PSU has not lifted the bandwidth restrictions for Napster. So, it's essentially better to steal the song once than to stream it twice. I know you can download them in DRM form, but streaming makes more sense if you can't burn them.
I think it stinks to high heaven. PSU has no business in what I do with my bandwidth or how I listen/obtain music for that matter.
Sure it may be good for like the six kids with PCs and the brainpower to figure out how to use it.
Apple rated its 1000 song capacity based on 160k encoding of MP3's. However, now that they have switched to AAC encoding, they use the the 128k bitrate. So that inital 1000 songs was 1000 MP3's at 160k, the "new" 1000 songs is 1000 AAC's at 128k. I believe a "song" according to those calculations is an average of 4 minutes.
This doesn't make me particularly happy as a PSU student.
PSU already logs the amount of bandwidth we use here everyday, it's not too much of a stretch to have them give us our own P2P so they can track that.
I guess it wouldn't be so bad, but to force all students to pay for such a service is wrong.
And, be weary of anything you read in the Daily Collegian.
as a recent highschool graduate, a lot of my friends are getting ready to buy new comps for college. early on i told everyone to get a mac, having just purchased a 17" imac. like most folks, they refused citing classic arguments. one button mouse, ugly ui (mac os 9), no office apps, and so on. this led me to believe that most people are comfortable with what they have used all their lives. unfortunatly at school most graduates these days have only used macs with mac os 8. apple's penetration into the education market could be enhanced if only they could get the fozen bondi imac images out of everyone's head. i know the reception i got as a mac user was not always fond. luckily my old school just bought a boat load of emacs and ibooks.
I am fairly determined to get my rebates when I feel that the rebate amount warrents the effort. However, last August Apple ran a program (or scam) whereby if you bought a new mac, a 17" iMac in my case, you could also order an Epson printer and get the full price of $99 through a rebate. Well, a great deal of time elapsed till I got my mac, since it was a new model at that point. Eventually though i recieved it and sliced the box up to get the needed UPCs and serials. Since the printer was for my dad, we put his name on the forms and submitted it to Apple. A week later we got a letter from Apple saying that the forms were not correct. So we supplied the serials and UPCs again. A week later another letter comes, same form letter. My dad then called them and asked why the form wasnt being accepted. The customer service rep quietly told him that he was being told to reject as many forms as possible. Luckily, however, he said he would send our check out as soon as possible.
That transaction turned my nose to rebates and turned my dads nose to Apples shady rebates. I think its important to remember that companies can do a lot to get out of mailing your check. I'm sticking to rebates less than $50 just incase from now on.
