I am just about done building my bird tumbler. I have got it to about 21 RPM.
I need some advice on baffles for it. The tumbler is made from a 30 gallon plastic drum. What can I do for baffles?
How many do I need and what size should they be? Any suggestions
will be appreciated.

#'s and sizes of baffles will vary a lot between many tumblers. I've tried several different setups to find which one worked best in my opinion. I also have a 30 gallon drum. My door is cut in the side and is 12"x12". I used to have 3 baffles but now went to 2 and it seems to work better. They are 5" in width and stop 2" from the end of the drum. The reason for the gap is to prevent a bird from getting caught between the baffle and the end of the drum By rounding the corners off alot and leaving the gap it will allow for things to pass by. I once tried to have them attach to the side. Nomatter what I did there would always be a tiny crack that was great for grabbing a ducks neck. Even if you don't have a gap when you construct it, it could develop a small gap through temperature changes and just plain using it.
I've tried several different setups and that's what worked for me!
