If I had our old feeders from days ago, the PVC pipe would look to be the option I'd try next. We tried the Sharks Teeth, which worked for a while, leaving bloody paw prints all over them and no corn theft issues. Until the little buggers figured out climbing with muddy paws until the teeth were covered enough to climb, then payday.
However, after a potentially BAD feeder leg failure leading to a ladder/feeder fall from height, we changed our feeders out to Hang Em' High Feeders with the upgraded drill workable geared winch. We installed the varmint cages on them, which may have not even been necessary. Due to the angle of the legs in relation of the feeder suspended underneath them, when the coon climbs the legs and attempts to jump over, the angle propels them down at an angle under the varmint cage encasing the feeder mechanism. We have many pics on our cams over the years that showed the unsuccessful attempts. We almost invested in the upgrade spring loaded feeder plate, but did not, and did not suffer for it, sans one problem. We let our feeders run dry, then plug them with a tennis ball dropped in that falls into the funnel to block bees and wasps from giving us a nasty surprise late summer the next year when we prep them to feed again. We leave the motor set on a reduced spin time to keep the motor from freezing up, but the gosh darned mud daubers will actually build a mud nest, feeder spinning a couple times a day that corks the funnel to just above the feeder plate. The spring loaded feeder plate would keep that from happening.
I know this, except for the backing of the PVC legs does not really help you, OP, but if you would want to invest in a safer option as a feeder, and makes it much easier and safer for one person to handle, that also keeps coons out of play, the Hang Em' High Feeder is a nice option.
