here is a link to a photo of the things

O.K. Now that I don't need to register, I've looked at the
photo.
here is the text I posted at that site asking what they are for:
These are marked "J522-13", the shaft attached to the knurled knob is 1/2
inch diameter, the bore is .625 for .200 inches, 1/2 inch thereafter. The
knurled knob/shaft is captive. The rectangular steel piece is 1inch wide,
1.490 high, 3 inches front to back. Treated to produce black oxide, so these
were nicely made, but what are they for?
and this
I don't think more views will help. The large knurled thing does not turn,
it is a machined part of a 1/2 inch shaft that has a flat milled on it. The
'other thumb screw' tightens against that flat part. A pin, which you cannot
see in the photo, retains the shaft in the bore so I can't pull it out.
Hmm ... some observations:
1) The hole in which the knurled part is located appears to be
teardrop shaped, with the thumbscrew coming in through the
narrow end.
2) The thumbscrew's impression on the flat looks very like those
on high school chem lab hardware from the mid 1950s. For that
matter -- the body looks like something originally designed to
fit on a chem lab stand with a 1/2" upright rod.
3) There seems to be some discoloration in the center of the end
of the other one (which is knurled knob side down). Any clue
as to what that might be? It looks sort of like a confinement
for detonating something -- like the paper caps which used to be
common in toy guns.
4) What material is the knurled knob? Test it with a magnet
to see whether it is a normal steel, or some non-magnetic
material.
5) Given the anti-rotation flat, it is not clear why the knob
is knurled. Perhaps to align the flat the first time when it is
assembled.
6) It looks as though the end with the thumbscrew was sawed off
from a longer piece with a hacksaw -- and perhaps cleaned up a
bit with a file. It does not have the finish of a commercially
manufactured part.
I don't think it is part of a punch press, it's a bit big to be associated
with ammunition,
I agree with both observations.
it just baffles me. Worse, I have two of them, whatever
they are, and I'm afraid they are going to start breeding, and then I won't
know what anything is for....
If they haven't bred yet, I think you are safe. :-)
It might be used as a pill press -- but would be better with
some leverage to increase the pressure.
Enjoy,
DoN.
