Hi, Al. I have wondered about your sheet metal feeder. Do you fold all the edges that could cut the chickens?
The only edge that isn't seamed (folded) is the front side vertical edges and we de burr them so they are not sharp. Why? Because folding them means the door doesn't close as tightly as it can with a flat edge that has been de burred. I would imagine that a rooster could catch a comb on the edge, anything is possible. We have a saying in Oklahoma, farm animals are never completely safe around moving equipment or Oklahoma state senators.
As I have said earlier, I am being forced into making a batch of feeders here in the U.S. due to the Chinese virus problem. Can't travel to visit or supervise, my overseas shop was closed for months due to the lock down, even the supply chains are still in turmoil over there. I am going to try seaming those two front vertical edges and putting the top front cover on the outside of the feeder. I am also taking the chance to do a redesign to see if I can shrink some of the wasted space in the feeder in an effort to get the shipping box down in size while still holding 26 pounds of feed. Shipping has gotten outrageous, nearly double what it was when I first started selling feeders in 2011.
And I am trying to work in some changes that will allow the basic feeder to be modified with a drop cam latch that totally locks the feeder door, you simply cannot push the door open without destroying the entire feeder. That is gonna be expensive and reserved for those folks with bad squirrel problems. The squirrels can learn to use the treadle if there are enough of them and if they will cooperate but I have an idea that cooperating won't last long if it ever happens. I have the locking system pretty much perfected but the cost of making it needs reduced so I am hoping a redesign will help with that. It won't be an add on feature like the soft close, pretty much a factory job to fit the mechanism and there will be some trade offs like knowing that if the mechanism failed it will fail in the locked position which isn't the best. Gonna be for special situations where there is no option and you won't want to go on vacation and not have someone check on the flock. Might do some wear testing, motorize the door and see how many cycles till the latch cable breaks, then warn people to replace the cable before x number of months or years. If anyone has a game camera on their feeder I would love to know how many times a day the average feeder gets opened and closed.
