Done a lot of drilling myself...never an airplane, but I have drilled some of the finest quality holes on earth. If you have the proper dill bit, and know how to use it, you can always get some drilling action. Beware....it is habit forming.....and addictive!
I've used a water hose and a length of conduit to 'drill' under a sidewalk and driveway before.

Never used a water hose to assist in drilling....but I have used a few bottles of Southern Comfort.

It is hard to understand....but I think it relates to addiction. Addiction is a powerful force...a powerful killing force.

The Drill Bit Thread......I like it! However, if you have been here as long as I have and roamed the various Forums, you know that the OPs question (done in jest) is far from the most ridiculous seen here, and really...seen quite often. I think that was his point.....so many dumb and insane posts that ask such absurd questions or give such ridiculous views just finally got to him.

I recently read a post where a user complained about a shortage of Pentax lenses compared to Canon or Nikon. Said he may have to switch to Nikon because of it.....he's been a Pentax shooter for over 10 years.....has a kit lens and two low grade DA lenses......so I can see where he is really hurt by all these "lens limitations" he imagines? Insanity is alive and well, you can find it with ease in real genuine threads...not just Drill Bit Beauties!

Regards!


Havign been here for about 10 years I recall many threads asking what is better for me questions, where what is better depends on what the person asking the question wants to do.


And who cares how many lenses the maker makes, even with the number of current Pentax lenses available I could not buy them all. In fact, my only recent lens is the 18-55 that I got with my K100DS. ALL my other lenses are quite old, mostly the M42 Takumars. The range available overwhelms my capacity to buy.

I'm a driller.

I shoot holes all day long, every day. One job I worked I drilled 656 holes in an 8 hour shift. Produced enough aluminum and titanium chips to fill a 55 gallon barrel.

Yep.

I'm a driller.



One shift I drill, the next shift I fill. Drill and fill. Day in, day out. Building airplanes is all about drilling quality holes.


Sounds a bit like a dentist. Drill and fill.


Better than being a doctor, who is like a third world farmer: hack and slash.

Got to thinkin'...many years ago I did do some drilling in an airplane at about 30K feet....I just wanted to correct that so I could maintain my "Honest Rupert" profile here.

Regards!


One job I had to do was drill a 3/8" hole in a largel ingot of lead. Real hard. The lead was so malleable it formed long snakes that filled the drill flutes and the drill did not cut if off at the front end. Real hard to extract the drill bit from the lead.


Surely (Shirley) I was not using the best drill bit.

water while drilling glass

you can buy expensive bits or use concrete bits

both bore as long as you cool everything with water although southern comfort might do in a pinch (oil allows the bit to wander)

note: do NOT use a hammer drill

The softer the material, the faster the drill speed.

The harder the material the slower the drill speed.

a spritz of wd-40 or some silicone- or Teflon-based lube would have worked
I helped drill the weights for a cabinet clock that used lead ingots and that was the solution
works on brass and aluminum which aren't malleable but "sticky" as well

the second time I used brass tubing
heated it
drove it through the two inches of lead...lickety-split
when the tube cooled it was soldered in
cut off the excess tubing
peened over the ends

had much more abrasion resistant pivot for a shackle to fit in

after all of that, a neighbor suggested using the old crappy stamped sheet metal style of pilot+countersink bits
he was correct...with no flutes...no clogs

Back in the late '70's, while in Colorado, I saw an old beat up pickup, the driver wore a cowboy hat and had a bumper sticker that said:
I'm a roper not a doper.
Wonder if that's still true?

Not sure how I made the connection, just a memory flashback I guess.

in the early seventies that was pretty much your two choices
