Here are a few shots of my incubator.
It is fan forced
Holds 3 egg trays + a hatch tray on the bottom (about 140 bantam eggs)
Manual turn
Only 1 tray in it for the photos. At the moment, playing around with a BBQ rotisory to turn it into an auto turn. The best thing it only cost about $300 & works like a charm

What do yous think

Hi Sarah
I built it about 10 months ago and been used to hatch about 80% of my birds. All the pullets & cockerels in my photos were hatched in it. It works great

I use a BBG rotisserie to power mine. If you need a circuit to switch on and off, or even run backwards let me know.

Hey Denis, can you make a circuit that would make a motor run one way for a period of time and then reverse the polarity so it went in reverse for the same period of time which was then repeated indefinately? I have an egg turning motor that I plan to build into my bator and was going to attach a cam shaped block to the motor so that it would lift and lower the egg tray once every hour (it is a very lowly geared motor) but the idea of a rhythmically reversing circuit sounds even better.

If it's a DC motor, most definitely. If it's an AC motor I'm not sure, but hey a bit of research won't hurt me.

To reverse a DC motor requires just a DPDT relay (two switches that switch at the same time).

I can do microprocessor controlled, vary the on period and time between bursts and direction.

Be careful though, there is no guarantees same time going forward, followed by same time going backward etc. lands you in the same spot every time. Could creep etc. and eventually tip your egg tray upside down. But I had similar problems with steering on remote controlled tractor. Is easily fixed with a couple of strategically placed micros.

Ohh, I take my hat off to you guys with your linkages etc. I couldn't do it. I had to "invent" a different method I call the tilted turntable.

Put your egg rack on a very slow record player turntable then tilt the whole record player say 15 to 20 degrees. Make it turn about a third of a turn every half hour. Thats the general idea. I reckon I can build one in under 30 mins.

Sorry for hijaking this thread :oops:

Hi Denis,

I was thinking about making something similar with a wire frame that sat just above a stationary base. The wire frame would be attached to the egg turning motor and the eggs would sit on the stationary base and roll as the wire turner rotated. Trouble is, after looking on the net for a while I found a few people saying that this motion in one direction all the time would often result in low hatches an inspection of the embryo showed that there was evidence of twisting of the embryo around the yolk sac caused by the rotation of the eggs. So I scrapped that idea in favour of the egg shaped cam attached to the turner motor near the fulcrum of the egg tray with a spring attached to the other end (just a light spring so it would come back down smoothly). I am hoping to make the cam out of something like perspex so it is light and easy for the motor to turn (but with such a low gearing it prob has massive mechanical advantage so could turn quite hefty objects), durable in a humid environment, and easy to clean.

what you describe sounds like a microwave. I have an old microwave cabinet and I thought about using it. Would need the "Plate" the eggs sit on to move and the "wire" to be stationary.

BBQ rotisseries are cool because you dont have any trouble with trying to fit a gear or spline etc. to suit.

You also get multiple prongs etc. It would be a cinch to attach your wire frame bit to one of these prongs.

Don't pull a microwave apart as they can store very high voltage for years and zap you.
