880 is an incomplete set of cork borers. There are quite a few
missing.

878: Guess... Seems to be a device for measuring/setting pitch/grade/angle.
Unless it is a trick of perspective, the right side seems to not be
perpendicular to the bottom. Why would one want to measure the angle of a
near vertical thing? My guess is a mortar aiming gauge.

879: At first sight it looks similar to stroboscopic discs used to
set/check turntable speed. But... With 6, 91 (7x13) and 182 radial
markings, it doesn't make sense for common turntable rates. I still guess
it is used as a strobe disc, but I've no idea for what.

880: Unknown has already identified a set of cork borers.

882: Traffic light? Go/stop indicator for
cars/trains/horses/dog-sleds/camel-caravans?

883: Why would anyone want to check magnetic north alignment precisely but
only over a small range? Perhaps used to carefully calibrate deviation of
magnetic north from true north. For making maps of magnetic deviation?

881. Can't tell from the pictures, but it looks like a sodium press.
You stick a lump of sodium in and squidge it into spaghetti. Used as a
reagent in some chem lab processes.

883. Obviously electromagnetic, but I think it's more electro- than

880 is looks like a fixed bore gauge set for a specific item's bore;
probably a go/no-go check for a production item.

Thanks for the link, I was looking for one but didn't find much.

Someone told me that he was seeing two different tools for number 881, it
looked fine to me both at home and at work, but if you saw a photo with a
blue wall in the background, that was the wrong picture. I've just reloaded
both images for that number, so you should see the Stellon device assembled
in the first photo and dismantled in the second.

According to R.H. :

O.K. Posting from rec.crafts.metalworking again, as usual.

878) A device for measuring (or setting) to some degree of precision
the deviation of a surface from level.

The scale is not degrees -- so I might think that it is intended
to dial in a specific elevation angle for an artillery piece,
with tables converting that to range with a given charge.

The gear teeth are at the same intervals as the marking, so I
think that you pinch the two tabs to slide it to close to your
desired setting, and then rotate the knob to dial in a fraction
of one of those units.

The level vial is almost certainly a lot more sensitive than
anything except a Starrett "Master Precision Level" or one by
another maker.

879) I've never seen one of these before, but I suspect that it is
a form of air cushion bearing.

A Google search finds that NAPCO makes (or sells) automotive
parts and motorcycle parts -- but this does not look like one of
either to me.

880) I thought that you had put a similar one up in the past year or
two. It is a chem lab "cork borer". You select the tube for
the size of glass tubing which you wish to fit, and bore a hole
through the cork. It is also missing a central rod with a
knurled knob on the end which is used for pushing the cork out
of the smallest tube. The other sizes are cleared by using the
next size down.

Note that the free end of each is beveled. (Hmm ... *maybe*
what you showed before is the tapered brass core with a hinged
knife blade for sharpening these cork borers.)

881) For making *something* under pressure. Perhaps Vegemite, given
the Australian provenance?

I would have liked closer shots for the individual parts,
instead of that long shot with them all spread out along a
board.

882) A signal lantern -- perhaps for something like railroads.
You rotate it to present either the horizontal bar or the
vertical bar -- indicating "no-go" or "pass", I expect.

883) With that long a needle, it would be quite sensitive.
I think that it could be used in conjunction with a map and a
table to refine "sights". Put the map on the table, align the
object to the North-South line on the map, and rotate the map
and the compass until it reads zero, and then look around for
recognizable objects (and take sights to them) to determine
where you are on the map.


Now to see what others have guessed.

Enjoy,
DoN.

you may be almost right.
substitute 'plane table' for table and you may have it.

plane tabling dates from before the 1950's. the mapping surveyor went
to a spot and put up his plane table and levelled it. then put the
piece of paper on it positioned so that the point on the emerging
drawing was plumbed over the spot on the ground. the sheet was
oriented precisely to the detail and radial lines drawn to prominent
objects. by moving around to other points and plotting to prominent
objects the entire detail could be developed on the map.
you would only need a needle with a small movement to aid in
orientation of the map.

I've never actually seen one so I'm guessing and the technique
predates my surveying time.

a land surveyor's plain tabling compass is my guess.

is indeed used with a Plane Table. See the following links

It looks like a chain hook. Not uncommon, except for the flattened part

And one minor objection to your description of the use for the
cork borer. You said:


================================================== ====================
Cork cutters or cork borers, used in labs or drug stores to make small
corks.
================================================== ====================

And I say that it is not to *make* small corks, but to make
*holes* in corks to pass glass tubing through -- including medicine
droppers.

Later -- chem labs were supplied with pre-bored rubber stoppers
with zero, one, two -- or possibly even three holes -- depending on the
complexity of the setup.

Enjoy,

879 could be an atomizer disc for a rotary paint applicator used in a
high volume electrostatic paint booth.

http://www.sames.com/en/products/for...aint/index.php

Take a look the PPH 405.

The discs have etched sections, interupted by plenum rings. The paint
follows the smooth path between the edged segments rather than the
rougher/etched section. The etched sections also set up a Magnus
effect, directing paint somewhat by increasing friction. The majority
of the paint-spray is directed by high voltage electrostatic
attraction.
Different size discs are used to vary the relative speed at
circumference as viscosity differences in paints dictate and 'leap-off"
atomization occurs...

Anyone for a game of Balderdash?

881 (or is it 882?) Is a set of rubber or cork stopper hole "punches".
Found in most college chemistry labs. You twist them into the
rubber stopper - the sharp ends do the cutting.

I have no idea what an 'ointment press' is. I figured ointment (such as
lip balms, etc) were poured into their containers as liquids and
allowed to cool, not compressed into them.

Knowing that Stellon was a dental equipment factory, I think the
crucible-type thing on EBay was the container where you mixed up the
acrylic before you poured it into the mold. I have no basis for this
(yet, but I'm looking), but I suppose that the central metal cylinder
in the press could have served two purposes: first it was stored in the
press as a 'spacer' to hold the whole thing tightly together between
uses. Then, the dentist or technician would place the cylinder beside
the press, place the cruciable on the cylinder (maybe over a burner?)
while they mixed the acrylic, and then pour it in the mold which was
placed in the press until it cured.

Like I said, this is just supposition. Any dentists here, or dental
technicians?

I'm sure they could also have been used to make holes in corks for tubing,

Corks to fit in a bottle have a taper (except for wine corks,
which are compressed through a necking device for the purpose of
obtaining a snug fit). Anything produced by these would be straight
sided.

(or of that fails due to wrapping, connect to:

http://www.fishersci.com/

and use the search entry to look for "cork borer"

In particular, the description for one of those offered reads:


================================================== ====================
Cork Borers; Will bore holes in corks and rubber stoppers; Plated
tubing; Smooth plastic handles; Handles stamped with number designation;
Set of 3 ranging 4.8 to 7.8mm
================================================== ====================

And there are other sets going up to "Set of 15", all of whose
descriptions are identical other than that.

Aside from the vendor being more likely to know the use than a
dictionary writer, consider the term "borer", which is an object to make
a hole in something -- not to make what came out of the hole.

looking at the photo. I'll need stronger evidence before I agree that the
