345. Not seen one like this, but appears to be a calculator; "slide
rule" style"

346. Leather punch?

347. ??

348. Drill chuck - end on?

349. electric motor?

350. Almost a "blunt" horse spur; although not seen one with flat
'spur' like this.

345 Stop watch with scales for speed measurement.
346 Tool for making square holes
347 Valve handle
348 Kitchen machine (mix master) chunk (or whatever)
349 Funny magnetic experiment. However, I cannot see that there is
really a spool. Might be some sort of magnetic cannon.
350 Your son's mischief tool. Needs a leather patch, a rubber
string and ammunition. (What is this called in English.)

350. Aha! Methinks you may have it :-)
Perhaps a part of a shanghai, ging, slingshot, catapult or whatever
name it may carry around the world. The rubber and shot pouch are
attached to the holes in the two arms.

345 Stop watch with scales for speed measurement.

I think the watchmaker's term is "tachymetre". An old Omega catalog I
have says that it is a shortened version of (get this)
"tacho-productometer" ! I personally believe this to be a
reverse-acronymics example, the original term makes perfect sense in
French.

349. Electric motor?

350. OB-GYN stirrup?

345. I think it's part of a planimeter.

346. A power mortising chisel (lacking the drill bit)

348. Drill chuck key.

Btw, I was just kidding about that last one. It looks like a pin wrench to
me.

As I see it, either the off-center weight of the coil, or the
enamel is scraped off the contact wires only on one side. (I haven't
bothered saving the images and zooming in to see whether there is
sufficient detail to tell about the enamel.)

Good picture. My Galvanometer (it is older) model used a Horseshoe magnet that is
set and the coil is very long with a pointer. It is a very, very low current device
and was used to measure charge storage (flow) thus current. It was built by GR -
General Radio and mounted in a Fine wood case with a black plastic-like top.
Lab grade. The box is now on display at Department of Energy as an instrument
to measure the current delivered by a Hydrogen Fuel Cell that I did the tech work
for a local group (My wife was the Primary Teacher at a private school that had a grant!).

Don's guess is correct, the coil is made from varnish coated magnet wire,
each of the two axles has had half of this insulating varnish scraped off,
making them function as primitive commutators. I tried Carl's idea of
scraping off all of the varnish and got the same results he did, it still
worked.

If anybody wants to make one, it works best with very thin wire.

Amazing! This /is/ something to impress today's kids with, because
they are used to that you have to buy things from the computer store
or whatever. But here you can pretend to just find some wire, a used
battery and so on. Need to try this. The wire is something I don't
have in-house, so I'll need to figure out which store stocks such
items.

If you have an old (and preferably dead) wall wart (the
oversized lump on the end of power cords for lots of portable things
which plugs directly into the wall), they normally have a small power
transformer inside. You can recover a lot of wire from one of those --
in two gauges. The finer wire would be wound closer to the center, and
connected to the power line, while the slightly coarser wire (probably
better for this task) is wound on the outside to produce a low-voltage
secondary to power the device -- whatever is is.

Enjoy,
DoN.

I forgot to mention that it works best if you use a very strong rare earth
magnet, and for the coil wrap the wire around a C battery ten times.

Grandsons had a ball with stuff like this when I got them an electric hobby

including simple motor similar to this.

You can pull a few rare earth magnets from most junk hard drives.
Probably scrounge the wire too.

In the US, Radio Shack. They sell a pack of 3 sizes on small spools.
It's called "magnet wire", just in case nobody's mentioned that yet.

That's what I used for the coil wire, the heaviest gauge wire that came in
the pack didn't work for some reason, but the next size worked great.

345. A calculator that functions in a similar fashion to a circular

347. A puzzle. The objective is to remove the nut with the four handles.

the axle.

My Dad still has several of these.

They're labeled from a maker of aviation charts, so it probably saw
application with manual navigation methods.

One is attached to strap-on knee boards. I don't recall what was on the
other knee.

I should probably make a puzzle out of it, but I'll go ahead and answer it,
I put two small wires on either side to keep it upright. Not much gets by
this crew, I didn't expect to have to anwer this question.

O.K. from rec.crafts.metalworking again:

345) Not fair for me to guess, since I submitted the photos.

346) Used with an appropriate sized wood-cutting drill bit to cut
square holes. The drill bit cuts out wood at the center
(ejecting it through the slots up higher), and the hollow chisel
bends wood from around the drill hole into the path of the drill
bit, resulting in a square hole. (Usually used for mortising in
things like a door lockset.

347) Used for adjusting the height of something -- such as perhaps
the rear of a cannon barrel to adjust the range.

348) The business end of a Jacobs style chuck key.

349) An electric motor. The coil is suspended in the two loops
at the ends of the battery, and current through the wires
produces a magnetic field which interacts with th field from the
permanent magnet(s) on the side of the battery.

It looks as though the wires coming off from the coil are just a
bit off center, so as the coil twists, it will probably lift
clear of contact at at least one end, allowing it to flip around
and repeat the cycle when it next makes contact (probably near
the end of a revolution.)

Even if the wires were perfectly centered, if the enamel were
scraped off of only one side of the wire, it would work pretty
much the same, with the enamel acting to interrupt the current.

350) "Slingshot" handle (not truly a slingshot, but the only term I
knew for this as a kid is most certainly quite politically
incorrect, so I won't mention it here. :-)

It looks as though it is designed for the rubber bands (perhaps
surgical rubber tubing) to fit through the two holes near the
ends of the fork.

Now to see what others have figured out.

Enjoy,
DoN.
