I was working with metal today trying to make a tray to put the egg holders in, and then i need to make it so i can quickly turn all the eggs by moving one side up or down. So i need 2 trays and a frame. I don't think i could fit 3 trays stacked up. Any way, i got one tray made. Working with metal is so different than wood! It is really hard to cut, so i was scoring it with a hack saw and then bending it back and forth until it broke. Drilling holes is hard too, and then getting the bolt through 2 holes and screwing on the nut. But it will be strong and easy to clean. I need to make another one at least.
