This shows the deflector in action spreading out the
falling material, such a simple and easy feeder.

This is in the sluice box with feeder removed I fed some
concentrates to it and you can see the gold mostly at the
center front of the wire mesh. Gold is so heavy it doesn't
 want to move further.

The Bird House has groves cut into the bottom side
supports to slip onto the sluice box.  The bottom is
cut at a slight angle so as to set level on the sloping
sluice box.

Plans for the Bird House Feeder

The deflector is just a piece of tin or alum bent to
adjust the spreadout of the material.

Another view from the front, I wish I had this combo
years ago to run those small amounts of material you
acquire now and then. Good luck out there.
