Sounds like what I have now, the little giant, similar anyway.lets see if I can talk you through building the feeder.
cut a 2x6 block so it is square. 5 1/2 x 5 1/2 inches.
center it on the bottom of the 5 gal pail.
put washers on screws and screw through bottom of
bucket into the block of wood. one screw at each corner
and a couple towards the center of the block..
then drill some holes around the block of wood
through bottom of pail. about six 1 1/4" holes.
now drill about six similar holes equally spaced
around the side of the pail about 3 inches from the
bottom edge of the pail.
turn pail upside down and place the feeder pan
centered on the block of wood. use screws with washers
into the block of wood spaced like you did from inside
the pail.
you are done. put some feed in it and see how
you like it..
Maybe if I hung the feeder like I am suppose to be less mess. But I kinda doubt it.
The plastic ports will be here Saturday, warm Sunday give it a try.
