<div><div>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. </div>
</div><br>
<div>Anyways, any ideas of how to install rubs inside them so the rocks don't just slide inside?</div><div><br></div><div>I'm just a little concerned that it will be hard to glue unless I can find the right solvent.</div>
<div><br></div><div>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. </div>
<div><br></div><div>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.</div><div><br></div><div>Any thoughts?</div>
