after paying $30 for a galvanised auto waterer, i made one out of a lowes bucket and top $3.60 there, and drilled a hole in it and sat it in a pan i already had. its summer so i just use the lay out dishes and the galvanised one i purchased which is a pita for me right now.
I refused to buy a galvanised auto feeder for the same amount after being unhappy with the waterer, i have built some out of wood, but i like what ive done here.
I dont know how much one of these cost OR how much just a round galvanized heating duct costs, but i assume its not much. The pan is $3.99 at
TSC, i got the brackets on clearance, i have a scrap pc of 2x2 under the stove pipe( it has never been used, btw).. so i only invested $5 in this feeder... i had enough brackets for a buck , and scrap 2x2 and two of these tubes, i bought a second pan... i made TWO for $9!
sorry its dusty lol i just had filled it.
