dlaery Posted December 27, 2011 Report Share Posted December 27, 2011 I want to build or assembly a small INSIDE (its cold outside) testing tank. I want to use to test different kinds of spinners. I am thinking a big plastic tub, rectangle shape, maybe 5 gal, and an agricultural water pump of some kind. What kind of flow would i need? I am just looking for somewhere to start. Or does someone have a better idea? Quote Link to comment Share on other sites More sharing options...
