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.
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
Here is his reply:
"Well depending on how you hold it, it could go either way. They turn both
Clockwise and Counter Clockwise.
It is as almost as if there would have been a handle that would fit on which
side you choose and then the other side would have been inserted into something
you could turn it at a different rate of RPM."
O.K. Not really the answer to my question, as that much was
obvious. (Other than what appears to be a different square on the two
ends, so they probably did not fit interchangeably. :-) I was more
interested in whether the tapered square was the slower or faster end.
