We found one of these on a property we bought and now have made 4 or 5 with buckets and several just the pvc pipe. Regular 5 gal bucket, a pvc toilet flange, 4" schedule 35 pipe, a wye fitting, a little more pipe and a cap. We drill holes in the cap to let water drain. All said, about $16 for the setup without buying a bucket. We get plenty of those for free. Holds 7-8 gal of corn. We keep them failry high off the ground to prevent NBA playing coons. Also the plastic tilt a wheel on top keeps coons from climbing down the tree and chewing through the bucket lid.
