I rescued this from a coffee percolator. It's stainless steel and has raised slots stamped in to the lid and the base and a stainless steel tube. I'm thinking that there's some way to incorporate this as a filter or manifold for all grain. Just looking for brainstorming ideas before my wife makes me toss it out.
You have to provide some type of scale or dimensions. I do not know if that is 3 inches or 30 inches across. Being that it did come from a coffee peculator which are closer to 3 inches across I say make a hopback.
A buddy of mine does small one gallon all grain batches using a short walmart bought cooler and a steamer basket as the false bottom. Works great for him. Sounds like you could set up something similar for test batches.
