Building an egg turner or buying one?

[Oklahoma Lightning]

I spent five hours trying to figure this one out.
If I have four trays and pay what $49 a tray that way to much money.
My understanding hubby would blow a fusses.
But what other choices do I have,

What kind of incubator do you have? If you look at the homemade bators on this site there are some simple creative ways to make a turner. Good luck
