I made a bird feeder last year and my wife said it was too small so I made this larger one that hold about 15X the amount of bird feed.
It is made from 7/8" ceder that came from 100 yr old telephone poles. The sawyer said the logs/poles had 85 rings on them.
I put a diverter in the center on the bottom so there is no feed laying is a dead spot in the center of the feeder- it drives it all to the slots on the bottom of Lexan panels.
I was going to put magnets to hold the top on but I think it is heavy enough not to move in a wind storm.
In the feed area a I put aluminum screen wire and drain holes in the bottom of the pockets under the screen to let the moisture drain out if it gets wet.
All the fastener are stainless and it has no finish. I want it to weather naturally and turn gray. The whole thing is screwed and doweled together so it can be totally disassembled and parts can be remade if necessary. Squirrels can access it from the tree and they can be real destructive on feeders
