It has been two years since the first "Rodent-Free Bird Feeder", so it's time for a second generation version.
So, from this:
To this:
This time it will have four posts, channeled along two adjacent sides to accommodate four thin Plexiglas (clear polycarbonate) to hold the feed. A threaded rod will secure the top cover directly to the base. The original 2-inch PVC stand and base will be reused.
To accommodate the four posts that have square cross sections, I drilled four holes first then with some chisel work, I created the square holes.
Bottom base of the new feeder had to be fashioned separately
Used marine plywood for the base
Cutting the clear Plexiglass
The seeds are "metered" by adjusting the gap between the bottom of the Plexiglass and the base, as seen below:
Still, effectively rodent-free with Vaseline smeared around the PVC post.
