Trommel Sifter Sawhorse Roller Adapter

I built a trommel sifter for stuffing my compost around a pair of Task Force sawhorses and Home Depot buckets. I don't know if those sawhorses are still available, I've had them for years. Anyway the rollers are these 1 ½" casters. I used ½" hardware cloth (I wanted 3/8" or ¼" but my Home Depot didn't have any in stock and I was impatient, I might wrap it later). I used aluminum pop rivets and washers to hold everything together, you could use screws but I am a big fan of pop rivets, they won't loosen up and fall out over time etc, they're a great permanent but removable solution.

To cut the buckets I used a nibbler tool that attaches to a power drill, not this one exactly but the same idea.

The angle of the trommel sifter can be slightly adjusted by folding one sawhorse up slightly to raise it, and a little further by bringing the rollers closer together on one side and further apart on the other.

I haven't used the trommel sifter yet (I just built it!). I anticipate just spinning it by turning it manually with gloved hands. I think a simple hand crank could easily be adapted onto a bucket lid with some holes cut out for the material to fall out the end, or maybe directly to the lip of the bucket if it is small. Alternatively, there is an extra groove on the bucket that would be perfect for attaching some type of belt to a hand drill or motor.
