For this project, you'll need a site with access to electricity, a small recirculating pump (choose the smallest one available; you'll need only gentle water pressure), and two grindstones measuring about 16 and 23 inches in diameter (look for them at salvage yards and landscaping companies).
- Small recirculating pump
- 2 grindstones
- Shallow whiskey-barrel liner
- River rock or chipped brick
- Mulch, rock, or spreading plants
