Auto egg turner

[Bearchell]

I just made an auto eg turner for my bator and I want to know how fast is too fast? And what is recomended? Right now it tilts from one side to the other in about 20 - 25 seconds so it's a litt over 1 rpm. In and around there... Is that going to be too fast?

I have two of the Brinseas.. the auto turner has this in the product description "Egg turning with all models in the Octagon incubator range is achieved by rotating the whole cabinet through 90° (45° on either side on an hourly cycle)."
Now.. I'm not sure what would be considered "too fast" or at what point the movement would damage the air cells or the embryo.. so hopefully some one else has that info for ya...
