My modified egg tumbler - This is not my design, but I did a slight modification to another design that I saw.
The parts that I had to buy came from Home Depot at the total cost of $5.00.
Here's a look at all the parts needed for this design.
Two 1 1/4" pvc couplings, one 1 1/4" pvc elbow, one fluorescent light plastic cover, window screen, zip ties, suction cups with bracket, and sissors.
Step 1 - Use the sissors to cut the fluorescent light plastic cover. I used a 3 1/2" piece for the egg chamber and a 6" piece for the upper section. I may shorten the 6" section later if it doesn't need to be this tall.
Step 2 - Cut the screen for both ends of the egg chamber. I laid a piece of screen over the coupling and cut around it leaving a 3/16" overhang. This way you don't have to do any trimming after you join the pieces together. I used 1 1/4" pvc couplings because the fluorescent light plastic cover fits nice and snug inside the coupling with the screen. If you use a 1" pvc coupling, the fluorescent light plastic cover fits over the outside of the pvc coupling. I tried to use this design with the screen, but it was just to tight for me. So I modified it and used the 1 1/4" pvc couplings.
Step 3 - Place the screen over the coupling. Take the 3 1/2" tube, place it over the screen and push them into the coupling. The tube only goes inside the coupling about 1/4". You will still be able to see the eggs nicely, once you place them in the tumbler.
Step 4 - Attach the suction cups to the other 1 1/4" coupling. I used a bracket from an old hagen elite heater. All I did was cut the arms off that wrapped around the heater.
Step 5 - Take the other piece of screen and place it over one end of the coupling that you just added the suction cups to. Take the other end of the 3 1/2" tube and place it over the screen and push them into that coupling.
Step 6 - Insert the 6" tube into the other end of the coupling that has the suction cups on it. If you want this tube to fit firmly inside this coupling, use some pipe thread tape around the edge of the tube before inserting it into the coupling. I didn't add any to mine because there is no danger of this piece falling out, unless you turn the tumbler upside down.
Step 7 - Place the 1 1/4" elbow on top of the 6" tube. You may also want to add some pipe thread tape to the top edge of the 6" tube to hold the elbow firmly in place. Again, I didn't use any on mine.
Step 8 - Now all you have to do is run the airstone and airline through the elbow and down to the screen. I'm going to use a gang valve to control the water flow through the egg chamber. I may also drill a hole in the top of the elbow so that the airline can come strait out of the top. Here's what the finished egg tumbler looks like.
