the fabricator notices that he keeps dulling his drill bits. There are two reasons for that.
First, drill bit rpm is TOO HIGH. Stainless steel has poor thermal conductivity, and will not draw heat away from the drill bit very well. The drill bit cutting edge will go over temperature and soften and dull over.
This nice PDF chart should be printed out and put next to your drill press:
and you end up with for a 1/4 inch hole
30 ÷ 0.262 ÷.25 = 458 RPM
Thats about 7 revolutions per second.. pretty slow.
These reccomended RPMs/SFM are for factory production where time is money. I usually run at a lower RPM than (half as fast or less) because I am not in a hurry. The drill will last much longer the slower you go.
The second problem is the work hardening of stainless steel. If the drill bit is allowed to rub the surface without making a chip for even one
revolution, the surface of the stainless will harden and dull the bit. You must press hard so that chips start forming immediately. If you must stop to raise the drill to clear chips for deep holes then raise the bit very quickly. Don't let the bit rub in the hole without cutting at any time.
Finally, the cutting lubricant: I use rubbing-alcohol+water mixture. It boils away in the drill hole to cool the bit, and does not leave an oily mess on the work.
The more power you want to broadcast, the more energy you'll need to do so. If some large radio tower company wanted to block EVERY FREQUENCY for hundreds of miles, do you know how much it would cost them? Look at just the FM radio spectrum -- they couldn't afford it. A 50,000 watt radio station broadcasting at one tiny sliver of a frequency has a HUGE electric bill.
Blocking other frequencies does not require multiple stations.
You can trivially broadcast over a very wide band of freq. with a spark gap or a tesla coil design. Keeping a broadcast within band is *hard*. Sending out crap over a big frequency spectrum is easy.
Public edit logs reveal that Wales has changed his own Wikipedia bio 18 times, deleting phrases describing former Wikipedia employee Larry Sanger as a co-founder of the site.
If Larry Sanger was a co-founder, (I don't know and don't have time to check) deleting that fact is at the very least petty and vindictive. It does not really matter if
it is or is not against some "code" or "guideline". Giving credit where credit is due is the right thing to do. Deleting credit over and over again... well, you will each come to your own
conclusion.
Claim 2 from Wired:
Cadenhead said other Wikipedia editors described Bomis Babes as "soft-core pornography," but Wales changed it to "adult content section" on Sept. 4, and later twice removed references to pornography, instead describing it as "Bomis Babes blog based on Slashcode."
Going to Bomis Babes here: http://www.bomis.com/tree/babe gives me two sponsored links at the top of the page, cut and pasted one of them below:

Your chicken little hysteria is doing more harm then good here. Let's save the concern for when the govt. does do things wrong, like Ruby Ridge, Waco, No knock warrents on the wrong address, using MADD personel to man roadblocks, etc.
There is the story of the Boy Who Cried Wolf. Hand wringing about nonissues ends up making the public insensitive to REAL problems.
And don't quote Pastor Martin Niemöller at me either. People are not being rounded up and taken away.
Generally dark and poorly ventilated, they cater to gamers who tend to smoke heavily. The bad air and light can increase the danger of sudden death, experts warn."
So the games themselves do not cause death. Instead, and unhealthy environment, poor nutritional habits, and general Lard-assed-ness cause death.
Who knew?
Next we will discover that video games don't make you kill others, and that guns just sit there unless some picks them up and uses them.
the buyer instructed his credit card agency to cancel the transaction, leaving PayPal 250 pounds out of pocket, so they deduct it from my account, which automatically charges my credit card 250 pounds.
So do a chargeback yourself.
PayPal tries to make profit without risk. Fuck'em.
The definition of the word "crossfire" as it pertains to a physical object:
A short circuit between two spark plug wires on an engine which causes a cylinder to fire at the wrong time, or causes more than one cylinder to fire at a time. It is a BAD THING (tm).
Now, it is perfectly normal that Chrysler pick the same word for one of their new cars, truth in advertising and all that. But the people at ATI don't want to have a name associated with a malfunctioning ignition system.
1:
Take a cardboard tube that contains greasy, salt-laden + crumbs material.
2: Using a dremel tool grind out the sheet steel bottom. Leave metal swarf and dust inside tube.
3: Glom this mess onto your camera and lens.

Seriously, read the article. The complete carelessness is horrible. This article is like a sick joke on people who don't know or think about the implications of getting salt and metal dust into their camera.
(scroll down) shows a guy sitting (floating) in a vat of it. My high school chemistry teacher used to
demo mercury by putting a little puddle in each childs hand.
Funny how you managed to leave out the important part when you did your little bit of selective quoting.
Let's continue:
Podkeyword did not carry a notice on their front page, nor on the page where URLs were submitted, that they intended to republish submitted RSS feeds under feeds controlled by podkeyword. Remember, an RSS feed is the front door to your show. You would think that it would be basic human decency to ask permission before creating an alternate RSS feed URL for an existing RSS feed. But not only did podkeyword.com fail to ask permission, the site went right ahead and created these alternate feeds and then didn't even bother to tell me!
So what PODJACKERS are doing is copying the work of others without permission or ATTRIBUTION and then redistributing that work to make a profit on, ads, etc.
Maybe that's A-OK in your little world.
I think it stinks.
But hey, I voted Republican, [MOD DOWN
ALERT] so maybe I just have too much of a concern about right vs wrong.
From the desk of Paul Belien on Wed, 2005-11-23 00:08
When conversations turn to health care, I am always reminded of my grandfather. He was 91 when he died. He had never been ill. He had never needed medical treatment in his whole life. Upon reaching his nineties, however, he required prostate surgery.
Like all Belgians, my grandfather had paid wage-related contributions to cover health insurance throughout his entire professional life. The Belgian health care system is a so-called pay-as-you-go system. Today's young and healthy do not set money aside for their own future needs, but are compelled to pay for today's sick and elderly. As my grandfather had never needed much health care, he had been a net contributor to the system. Now was the first time he was going to claim something back.
He had his operation in May. In November he was dead. The prostate operation had gone fine, but afterwards the hospital had given him an antibiotic drug that caused complete deafness. Though there were other, but costlier, drugs available, the hospital gave the old man the cheapest one. They knew about the side-effects, but it did not strike them as an unreasonable and unjust thing to do. Why should it? A man who has already had 90 healthy years of life surely has no right to complain about deafness when some people get more seriously ill or die at a far younger age. When my grandfather left the hospital he was completely deaf. He lost his will to live. Six months later, he was dead.
....
Soon euthanasia might be the price the solidarity principle of the welfare state imposes on those people whose health care is costing society the most. Politicians in Belgium and the Netherlands have already granted their citizens a "right to die" by means of a lethal (and cheap) euthanasia injection. Is this a new "freedom" that the state, which is constantly restricting every other aspect of our lives, generously bestows on us? Or does it boil down to "economic euthanasia," which enables governments to save money by eliminating those that cost the welfare state too much?
Since it works for you, great, but normally you should add kerosene (parafin) or diesel.
Gasoline has additives to raise the octane level, and those additives would tend to make it hard to auto-ignite (detonate) the fuel in a diesel engine.
Diesel fuel is measured with a cetane number, which is sort of one over octane.
You are comparing apples to aardvarks. Tivo functionality can be changed at will by the folks at Tivo. The feature you love today may be replaced by the feature you hate tomorrow.
A Myth box is yours, and no one from the outside will mess with it.
So, yes, in $ terms the Tivo is cheaper if you have to go out and buy all the Myth parts from scratch (but most of us have parts lying around we could use) but you are getting something over which you have complete control, whereas the Tivo is controlled by Tivo.
Ob. Disclaimer: I stopped watching broadcast TV about 10 years ago. I did borrow the firefly DVD set from the library, though, but I will wave my hands and claim that does not count.;)
What people (bloggers and their fans) don't understand is that journalism deals with being able to write coherently, using facts, and as little bias as possible.
I'm not sure if I should mod you + funny, or if you are really serious.
Technical articles in papers have consistent factual flaws. War articles consistently
focus thru the soda-straw lens of Vietnam (isn't it time to Move On, already? sheesh!) and ignore any progress in order to focus on the latest body count.
Walter Cronkite may have gotten away with that back when Ted Kennedy was learning how to walk away from drowning victims, but nowdays people can go directly to the source to get information. Abandoning any pretense of objectivity, Wally actually came on the TV news and told us he opposed Vietnam and that we were doomed (that helped us win, huh?)
People can only be made to believe bullshit when they have no competing source of information. Those days are coming to an end, fortunately, and the partisan lies and manipulation of MSM are now too obvious to miss.
Extroverts seem to rule the world or, at least, the USA, which hasn't elected an introverted president for three decades, since Jimmy Carter.
Heh. I remember Carter. His "introvertedness" if that's what it was, was beside the point. The man exuded a mopey hopelessness every time he spoke. His energy policy consisted of wearing cardigans on TV when he gave his "fireside chats", and telling us he was turning down the thermostat at the White House. His cap on gas prices resulted in gas shortages.
His foreign policy of "USA bends over and spreads them" is directly responsible for the mess that exists in Iran today, and in fact one of the hostage takers of the time is "El Presidente" of Iran today.
Carter may be capable of building houses, and beating off savage attack rabbits with a canoe paddle.
He was waaay out of his depth as a president.
Everyone should have to endure watching the man's speeches to America. Those who missed it won't understand what a dismal time that was.
