702) Cylinder hone. For wheel cylinders / calipers.
703) Probably a puzzle in how to get the cylinder out without turning
the block over. Science demo in how to use air pressure ( or create
vacuum ) to remove the cylinder.
704) Maybe for spin drying a paintbrush?
705) I used to use a steel / smaller version for turning cotter pins in
linework.
706) Roof vent / turbine.
707) Looks real familiar but can't quit pin it down.

702 Cylinder hone. From the size of it I would guess for small engines or
disc brake calipers.


707 Reel? Maybe for down-rigger weights--or lobster traps--or something
else you want to
crank up from the bottom of the ocean.

702. Brake cylinder hone
703. Water displacement puzzle. Inner block would be too heavy for
Bernoulli principle demonstration.
704. Paint Roller Water Extractor. Makes a huge mess if you didn't
fully rinse the roller of paint.
705. No idea, though I like the bed rope tightener idea.
706. I agree, roof ventilator, though I wouldn't have gotten it on my
own.
707. Corn Meal grinder?

707 Closest I can come is it looks similar to a corn sheller. While
turning, feed dried corn on cobs in the top, corn comes out the bottom, cobs
spit out the side opening.

My guesses:

702. Cylinder hone
703. The puzzle is to remove the cylinder from the hole without turning over
the cube. The science demonstration is about using inertia to solve the
puzzle.
704. Mechanism used to insert corks into wine bottles.
705. Used to tighten string or rope (perhaps on a loom).
706. Wind turbine, used to cool attics.
707. Sharpening wheel

Carl G.

702. Sunnen Cylinder Hone
704. Paint Brush and Roller Spinner
706. Top view of a spinny ventilator thing
707. Some sort of early kitchen utensil, ie coffee mill, flour mill,
corn something or other...

So, it's a meat grinder?

Actually, it looks to me very much like a knife cleaning machine that was
shown in the TV series, Upstairs--downstairs. Knife goes in through one of
the slots, and brushes revolve inside.

702 Engine Cylinder hone.

True story.

Many years ago took my new lighting specialist (LS), a lad with a
definite Irish name, to meet one of my good Jewish electrical
distributors(JD), first thing in the morning.

After a couple of cups of coffee and some chit chat, JD asked LS if he
was aware that Jewish male babies were circumcised.

My LS acknowledged he was aware of the practice.

JD then asked if he was aware of what was done with all those
foreskins that had been removed?

LS acknowledged he was unaware of what was done with them.

"Well," said the JD, "they get packed up and are sent back to Ireland
where the are planted."

"When they grow up, they come back to New York City and become Irish
cops."

So much for our introductory meeting.

Lew

According to R.H. :

As usual -- posting from rec.crafts.metalworking.

702) Brake cylinder hone.

703) Hmm ... not sure about this, as the fit looks a bit too lose
to serve as a demonstration of pneumatics. I suspect that it
would still drop in rather slowly, and drop out similarly
slowly, unless there is a small hole in the opposite side which
could be used to blow it out.

704) I suspect that this could be used to drive a corkscrew into
the cork fairly quickly, as long as the handle wings were short
enough so they did not interfere with the guide arms which
surround the rotating part. (I presume that only the part
inside that frame at the end actually rotates.)

It might also be used for fastening twist ties or something
similar.

705) Again, it might be used with a corkscrew, giving greater
leverage to screw it into a rather dry cork.

706) perhaps a folding reflector for photographic illumination?

Either for lamps or for flashbulbs.

707) Hmm ... for cranking out randomly selected Bingo balls when
running a game?

I don't see the inside, but I'll bet that it is arranged so when
you crank it counter-clockwise, it will just scramble the balls
in the housing, but when you crank it clockwise, a ball will
appear at each spout at a certain position during the turn, and
probably drop into a catcher on the far side -- just barely
visible.

Now to see what others have guessed.

Enjoy,
DoN.

They have all been answered correctly this week:





702. Cylinder hone

703. The puzzle is to remove the dowel from the cube without touching
either, the answer is blow across the top of the cube to make the dowel jump
out, a demonstration of Bernoulli's principle.

704. Paint brush spinner

705. Rope bed key, thanks to Karl for the link on this one, I've got the
same link on my answer page so save your time if you've already seen it.

706. Roof turbine vent

707. Knife sharpener

of the links is to a video of the cube and dowel puzzle being solved:

I don't think Bernoulli's principle explains it. You need more air
pressure under the dowel than over it, so it must work by deflecting the
puff of air down the side of the dowel.

I think you're probably right, I was just going along with what was stated
on the web site where I found the puzzle, but I was also questioning the
Bernoulli answer. I have noticed that if you blow directly from the side it
works less well, but if you blow slightly down it works much better. I
haven't been able to find any other web sites explaining this being caused
by the Bernoulli principle, so I'm going to update my answer page with the

Thanks, I like this link from that page:
http://user.uni-frankfurt.de/~weltner/Mis6/mis6.html

It says what's attributed to the Bernoulli theory is usually wrong
because moving air does not exert less pressure perpendicular to the
stream than does still air.

If airplanes depended on Bernoulli, they couldn't fly upside down.
Also, a high-lift wing would have a washboard surface for a longer path
than a single curve.

A stream will pick up air from the sides. If it picks up air near a
surface, there will be less pressure there, so the stream will bend that
way. That's Coanda. I'll bet the Wrights understood it.

That's how a curved upper surface makes an airplane efficient. The
plane provides lift by deflecting air downward. A flat bottom will
knock the air downward, but if the top were flat there would be
turbulence as air tried to accelerate suddenly to fill the vacuum. A
curve distributes the vacuum so the air can change direction smoothly.
The Wrights figured out just what kind of curve would distribute the
vacuum well enough so the parasitic drag wouldn't be too much for their
homemade motor.

Maybe the Coanda effect?
http://jnaudin.free.fr/html/coanda.htm

That would fit - the curved edge of the pin entrains the air while Mr.
Bernoulli is lifting from the top. ;-)

Airplanes stay up. Nothing increases the pressure below the wing, just
reduces the pressure above.

Suppose you have 1 ml of air under the dowel when you start and 100 ml
under it when it's halfway out. The pressure under the dowel will
decrease to 0.15 psi. You need to shoot a lot of air under the dowel in
a hurry to maintain 15 psi. If you're shooting air into that space,
who's to say whether it's above or below 15 psi?

Blowing air across the top of the dowel reduces the air pressure above
by 2-3 PSI (remember, that's Pounds per Square Inch.) That's the way

Where did you learn that? At what speed? Is that true on any surface?

Airplanes stay up. Nothing increases the pressure below the wing, just
reduces the pressure above.

In that case, wouldn't a wing with a rippled surface on top develop more
lift than a single curve by requiring the air to flow faster to follow
the longer path of the ripples?

Angle of attack has no effect? Can't airplanes fly inverted? Isn't the
curve on the bottom of an owl's wing almost the same as that on top?

6th grade Science stuff. Well, ok... Maybe 8th...

I've never known a school teacher to be wrong about anything.

http://wings.avkids.com/Book/Wright/...1_1902t38.html
That shows Airfoil #31, which the Wrights tested. Depending on the AOA,
it was capable of a lift/drag ratio of 8.45. Don't the top and bottom
look symmetrical to you?

It's the same old discussion. An airfoil gets its lift from 3 effects:

Archimedes?

Bernoulli studied incompressible fluids flowing without friction in
pipes. It takes pressure or height to make water move. If water was
flowing, he knew it came from a place where the pressure or height was
greater. The motion resulted from reduced pressure or height. It
didn't cause it.

I don't think he wrote about gases. If flowing air appears to suck,
it's because friction pulls air into the stream. In the case of the top
of an airplane wing, it's like what Bernoulli said about water. It
flows faster because it's moving into a place with less pressure.
