The ones in the pic were built out of some-what used plywood and some things I had laying around---had to order a few things. I built the turner, and used a rotisserie turning motor to start with to turn it. Had to change that because it was not strong enough the way it was set-up to turn 288 eggs. I could have re-geared it, but decided to just order a good motor.Wow! Well, I am really impressed!! Good for you!
