Here is Antler Carver's description & Picture:
Bottom of barrel has 3-4 in. hole. Bolt bathroom toilet bowl flange with 6 bolt holes to bottom of barrel under the hole,then plumbing tee on to the flange then 2 plumbing pipe on to the tee.
If pipes are cut off to short, grain will pour out, if pipe is to long, animals have
difficulty getting grain. Put grain in barrel first to see how far the grain comes out the pipes, then cut the pipes about 2-3 inches beyond the grain. We use oats.
We have moved it to about 30 ft. from dining room window for taking pictures. We have year after year pictures of some animals.
When weather warms up we quit feeding.
Cheers,
