Does anyone know how to make a rock tumbler?

okay so i need to make seaglass in like 3 days for a science project. i was wondering if anyone knows how to make a rock tumbler that would be quick and easy to make or if theres any place with a cheap rock tumbler i could buy. i would put the glass in the tumber and fill it with water and i need something im only 14 so i need something easy to make.

Yeah what Brian said is a cool idea. Don’t be shy to walk into the local jeweler place. They probably would get a kick out of it anyway to help you get started in polishing.

Another idea is maybe your school or high school biology/science teacher might use them? Maybe they’ll let you use one after school.

I just searched youtube for “tumbler” and alot came up. This gave me an idea for a cheap and easy tumbler with common household items. And I might try this myself to see how it works. I’ve always wanted a tumbler but I have never had the need for one.

Have your dad help you with this. I hope he is handy with some tools and has a hand drill.

Take a big plastic round mayonnaise jar. Get a machine threaded screw that is about 2 inches long and about 1/8″ diameter–one that can stick into a hand drill. (Like when you put a drill bit in the hand drill)

Drill a hole in the center of the lid the size of the screw.

Slide the screw through the hole from the inside, with a bigger diameter washer to grip onto the lid. On the other side of the lid, use another washer and then a lock washer and nut. Tighten down real good.

If your mom has a rolling pin or two, rig something up so the end handles rest on something securely. The jar will rest in between them, so the jar can spin freely.

Then tighten the hand drill chuck on the screw that is sticking out of the top of the lid.

If your hand drill trigger can lock into place and stay on then you can set it and forget it. Just keep it real close to your bench top so the handle touches the bench top and doesn’t rotate.

This could work–something quick and dirty for you.

But if you can get a motor, and handy with some wood and a saw, you can make something more sturdy and something to last.

But this should give you an idea of things to try.

Good luck! Let us know how it goes. 🙂
