I have a friend who loves to use deer feeders that will hold like 5- 40 pound bags of feed or corn, and wants help hauling them deep into the woods where he has amazingly located the perfect spot for this 30 pound battery operated tripod that will only be there for a couple of weeks each year. My suggestion to him was to build some kind of light weight gravity feeder that could be strapped to a tree or a fence post if permenant, and this is what we came up with. I am sure this has been done by someone before somewhere, but if not, it's about time.
supplies: 1-4' joint of schedule 40 or 80 PVC pipe (4",6",8",10") whatever size you want
2- PVC caps that will fit your choice of pipe (top and bottom)
1- PVC 45 degree cleanouts (y) shaped piece) (bottom)
Glue pipe into long side of (y) so the 45 degree angle (short side) will be angled upward. Next, invert one of the caps and glue it inside the very bottom of the (y). Strap the unit to a tree, (Do not nail or wire) or strap to a post, keeping the lower angled opening about 2-3' off of the ground and dircted outward. Fill with feed, place other cap on top to keep out rain. Gravity will fill the opening as the deer or turkeys eat it down. If you buy full 20 foot sticks of pipe you can build 4 or 5 feeders out of it. These directions can be modified to make various sizes of feeders, and being PVC they are light weight, rust and rot resistant, and can be painted any color you want them.
