What would be nice is a solid carbide drill. With it you simply apply power and the drill starts to cut. I have had mine red hot when it started to cut when drilling lathe bits. Those made of cobalt and are tough.
I made a forming bit. Drill and grind.
I bought mine from MSCdirect.com -

It's not that I don't like you. It's the fact you're an idiot & you waste people's time. :(
More money than brains.... an excellent example of the sad state of affairs in America. How's the oak firewood & poison oak doing?
Yes, and I've visited the site. Did you notice the emoticon that said I was joking with you?
At one job I had to take freshly minted techs and engineering students to try to turn them into usable employees. One engineering student started a fire by laying a hot soldering iron on a pile of paper towels, then he stood there screaming "Run for your lives, we're all gona die" He was standing in front of the fire extinguisher, so I grabbed the pile of flaming towels and ran out the front door to let them burn out in the parking lot. He had been shown where every extinguisher was, and there were squeeze bottles full of window cleaner that would have put it out. The last I heard of him was that he was working for RCA designing TV tuners.. I was glad that I was out of the TV repair business!
Another destroyed transistors by the handful buy putting them in wrong, then laughing about it. The last I heard, he workes at WPAFB in one of the labs. He was at R.L. Drake, till they got out of the ham radio business.
They were the cream of the crop. :(
Modifications must be made using natural products found in the Brazillian rain forest?

Then your original description of the desired outcome was incomplete / inaccurate. :(
You do not want to merely "hang the opener". You want it to be available for use AND you want to make sure it doesn't "leave". A different set of constraints.
Sounds like you need a lanyard system or a system to "train" the kids.
You have an amazing ability to complicate the simplest tasks and cause threads last a very long time.
I can only wonder what the next "hidden constraint" might be.
We're all wondering what will be the next specification to meet, on this project. Went from "hang on a nail" to "tethered to prevent loss".
The future modification should withstand
1000 degrees F, in case the kids put the opener in the gas grill, to cook off the tether.Christopher A. Young Learn more about Jesus
Heh heh ... you never did like me! :)
That's become a common misunderstanding.
Good marketing. Bad engineering.
Were they affirmative action hires?

Yes, to the Rodman bits. Guaranteed for life. I've had a few replaced. I only use them for special problems, but they have always worked.
As to drilling stainless, any good HSS (high speed steel) bit is capable with slow speed and high pressure. The bits may not last long, but should be able to cut. I agree with the comment about needing to get the cutting lips of the bit engaged.
No. It was a small electronics business, where the owner would hire people with little or no experience because they would work cheap. They were about a third of the employees, and were given the simplest jobs to start with. A lot had taken the Electronics course at a local vocational school.
Good morning Mr. Young. Just thought I'd let you know this mean spirited posting finally got to me and you are back on ignore.
Learn more about Jesus indeed. I think I've learned enough.
Uncle Steve Inscribed thus:
I've used a similar technique for drilling holes in glass bottles to make table lamps. A copper tube with a groove filed across the end dipped in grinding paste. Slow, but you get a smooth burr free hole. Smoothing the inside is a little harder. :-)
Ed Huntress Inscribed thus:
Interesting technique, I'll have to remember that one !
It can work well when the circumstances are right.
BTW, just so we don't leave in inaccurate impression: The case hardening on an '03 receiver was not the thin case we use to impart surface hardness. It was a deep case hardening applied with an extended soak in a furnace, with a dissociated ammonia atmosphere, and the purpose was to strengthen the receiver, not to harden it.
So it isn't like those 'smiths were just trying to scratch through a thin case.
A variation is to anneal the spot with a red-hot iron dipped into a drop of solder.
I don't maintain it any more. I'm just below my maximum quota. I should move the DNS record to point to: which I also don't maintain much because it's such a disorganized mess. Oh well.
Nope. I usually ignore imbedded hieroglyphics.
Sounds like me about 45 years ago. One of the other techs had started a small fire on the workbench with a hot soldering iron. I arrived to save the day by unloading 10 lbs of Class D dry powder from a large fire extinguisher into the flames, and all over everything in the shop. One big "whoosh" and the extinguisher was empty. It took about a week to clean up the mess.
I was on the receiving end of another brain dead fire extinguisher operator. I was working on a Rose Float at the college when sparks from a welder set fire to a small pile of oily rags and rubbish. We were all standing around the impromptu bon fire (it was a cold night) when someone arrived with a CO2 fire extinguisher. Standing on the opposite side of the fire from me, they unloaded the extinguisher, which blew considerable burning debris in my direction. I was able to get out of the way of this crud flame thrower just in time.
Some things just have to be learned the hard way.
Careful, those that can't do anything useful on the bench, eventually become managers.
At graduation, we attempted to guess the future profession and level of success of various notable engineering graduates. It was generally agreed that I would die in a spectacular explosion of my own creation.
Several people in labor, mfg, design, etc ... have no theoretical or practical knowledge in metalworking, but still take, send or broker related work out. My problem with people in this group is the sickening bigotry and the convincing sock puppetry.
My incident was about 40 years ago.
Still better than fighting a forest fire with nothing but a backpak water tank, and a shovel. :)
He's probaly laid off right now. He was told that the fiscal cliff 'Sequester" would cut the funding for the contactor he works for.
It IS nice to be rcognized for your talents. It's a good thing you didn't work at a munitions plant, instead of Lingerie. How many people have been killed by an exploding corset? :)
WHICH group? The thread is crossposted among four newsgroups.
