If you used a flat head screw and pre-drilled the hole, you should be able to have the screw flush with the outside of the jar. That'll of course only be an option if the jar is thick enough to have material removed without compromising its strength too much. The agitators would then also have to be bulky enough to accommodate screws. I can't tell how big this thing is from the photo, but thin fins and solvent will give you more room for rocks.

You should be able to determine the plastic type from the recycling
code on the bottom....
http://en.wikipedia.org/wiki/Resin_identification_code
Once you know the plastic, you can confidently select a solvent for
attaching fins...
Just make sure your fins are of the same material or compatible to
the solvent...
PVC and ABS solvents are widely available (Canadian Tire) for use
with pipe....

Um, because water is involved, I'm a bit concerned about screwing

Also, by doing something that interferes with the outside
roundness of the jar, it might not roll on the tumbler.
I'm not dismissing it. It sounds better the more I think of
it but it still requires the right solvent to seal it up...

Do you think the jar is tough enough to screw through?
If so, you could press the agitators against the inside
of the drum and screw into them from the outside.

I finally found some empty plastic protein
jars to use for my rock tumbling project. They
are large (like a gallon) and they have a wide
mouth. The plastic is very tough so I think
they will be okay as rock tumblers. They may
be made of vinyl I'm not sure.
Anyways, any ideas of how to install rubs
inside them so the rocks don't just slide
inside?
I'm just a little concerned that it will be
hard to glue unless I can find the right
solvent.
One thing I thought of is to add a disk
underneath the lid. So when you go to add the
lid (like a peanut jar lid), you first put down
a disk as if it were a seal. The lid would go
over top of this disk and hold it in place.
Then the disk could have some agitators
attached to it so that as the assembly turns the
agitators rotate inside the container and make
sure the stones don't slide.
Any thoughts?
