[Lab] protein jar tumblers

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.

Subject: [Lab] protein jar tumblers

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?
