What is it? Set 549

3205 I'll guess that these are [ancient] Chinese multiple rocket launchers. They hold 100 rockets, with arrows as stabilizing sticks that are fired as a barrage. I'll guess further that these are reasonably modern museum exhibits.

3206 Paint stirrer?

Easy one at 3205 - it was on Mythbusters. It's a hwacha, an ancient Korean multiple-rocket-launcher weapon.

3206 looks like a whisk, for cooking eggs or similar.

3205, colonial baby carriage for India Fakur babies in training. 3206, either radio directional antenna, fly swatter for huge flies, or egg wisk. 3207, radish cultivator, for small gardens. 3208, embossing tool for rail road tickets. 3209, no clue. 3210, no clue.

3206

I am thinking rug beater

#3206 - Rug beater? #3209 - Looks like the body for a hand held grinder.

Correct, it's called a hwacha, but I don't know if they are originals or reproductions.

It is a stirrer but not for paint.

Yes

It's used like a whisk but it's not for cooking.

Close!

Yes

I think it's for mixing size for wallpapering.

Steve

Correct!

Posting from the usenet newsgroup rec.crafts.metalworking as always:

3205) A strange thing. Is it perhaps a portable device for crushing sugar cane? 3206) An egg whipper?

3207) Some sort of fork designed to easily slip off whatever it picks up by operating the lever.

3208) O.K. Another interesting device. First off, it is built on a parallel-acting jaws pliers. The size looks close to that of the metal-backed buttons/pins, but the left-hand part is too small to assemble one without bending the backing plate, and the pliers are not really offering enough leverage to make it practical for this use.

So -- I don't know.

3209) The tapered square to the left looks like what is found on the shafts for winding tall clocks -- but it is the wrong gender to fit into a clock.

Out of curiosity -- which direction does the ratio go? Is the left or the right hand side the faster?

And how heavy (wide) are the gears? If they are thin stamped steel, they don't have the torque to drive much significant load.

Perhaps it is for something like spinning a wheel with holes in it to act as an "optical chopper" -- or maybe a hand-powered fan.

3210) Strange -- and I can't see enough of it to be sure, but it looks like it could scribe a diametrical line across the end of a piece of round stock. (More detailed photo of the spring loaded arm might give more clues.)

A tough series.

Now to post and then see what others have suggested.

Enjoy, DoN.

3208 a device to install the back on a pocket watch.

You're in the right ball park, the patent for this tool can be seen in the answers for this week:

Rob

Don't know, I'll email the owner and ask him this question.

Here is a photo of the gears that he sent, they look to be not very thin:

Thanks!

O.K. About medium strength, then. And while I don't know which side is up,. the side on the top is the high speed, and the one on the bottom is the low speed. (Assuming that the center gears shown are directly connected to the shafts. No real depth to the photo -- even if I save it and adjust the gamma to make it less dark.

Maybe it is supposed to have a fan blade on the high speed end, and be used as a hand-cranked breeze in hot weather?

Or -- as someone else suggested -- for a hand cranked grinding wheel (a quite small one). If it had a way to clamp it on a table edge, it could be for sharpening scissors or something similar. But I seem to remember a wooden handle under the gear housing, which is awkward for most grinding uses.

Enjoy, DoN.

Given that additional clue, before going to see that one -- let me state a secondary guess. It is for deforming plastic watch and dial indicator crystals. Push the center in relative to the ring and the OD shrinks a bit. Drop the bezel ring onto it so the edge of the crystal fits into the groove there, and relax the grip on the pliers to let the crystal expand into the ring.

I made something to do this -- using a drill press and the press part instead of pliers.

Now to see what the "hidden" answers really say.

Yes! I wish that I had seen this before I needed to make a tool to do this. (I used mine on crystals for various sizes of dial indicators of the sorts used by machinists.

I hope that this one has interchangeable parts, to adapt it to larger or smaller crystals. I had to make (so far) three different sizes. :-)

Enjoy, DoN.

They were right about one thing:

Pretty much unreadable. :-)
