I started thinking about the gravel I need to wash for the 75 I'm setting up & I realized it's going to take awhile with my standard method. Put the gravel in a bucket, add water, stick my hand in the bucket & swish it around. Pour the water off, add more & keep repeating untill the water runs clear. Here's what I came up with.
Cut off the bottom of the bucket & cut a strip about 2" wide.
Next, cover the bottom of the bucket with a mesh material. I used landscape fabric because I had some on hand, you could also use window screen. Next, slide the strip into the bottom of the bucket trapping the fabric between the strip & bucket.
Since I used a square bucket, I cut the bottom into strips to use for the next step. If you are using a round bucket, you can cut a second strip for this step. Fold the fabric towards the inside of the bucket & sandwich it between the backup strip & the bucket strip. Fasten the strips & bucket together with bolts or rivets & carefully trim any excess fabric.
Your layers should be as follows; the backup strip, a layer of fabric, the bucket strip, another layer of fabric and the bucket. All that's left is to place your gravel into the bucket, add the water & let it run until clear. It only takes a few minutes & by letting the hose do all the work, your hands won't even get wet.
