Does anyone have the details and measurements of this auto turner?
Hovabator !
I really need to see and know how it turns the rows of eggs, what type of cable or bar is connected to the motor, genially on how it works.

Can someone post me some photos of the mechanism on how it works and what motor it has please?

Thanks,
Kowan

It uses a 3W 220Vac motor that turns once every 4hours (1/240rpm). On the right hand side looking at that picture there is a guide that the motor arm slots into. the guide is attached to a rod that turns the eggs. As the arm on the motor turns it slides up and down in that guide while pushing/pulling the rod left and right.

I'll try to get some pics of it up close and post them. I'll look for a tape measure as well to get the measurements.

*broken link removed* (Admin)

That's a 300mm shifter. I haven't managed to find any measuring device.

Hope this helps.

Thank you very much Whitty,

exactly what I was looking for, I want to build one but to a different size and I needed to see how it functioned before I started.
As for the motor, I am using a microwave geared motor, the motor that turns the plate in the microwave.

Thanks again Whitty

cheers,
Kowan

Hi Kowan
Whats is the rpm of the microwave turntable motor?

My auto turn bator uses a similar "linkage" to tilt the racks up and down except I used a rotisserie motor that is switched by a electronic timer circuit

You may find that you rock and roll the eggies to much if the rpm is too high

Microwave motors don't have the grunt the BBQ rotissere motors have. Even in the microwaves they don't directly drive the plate but just turn the rollers beneath the plate. That allows it all to just slip if it gets a bit too tough for the motor. I've found that under a little bit of pressure the microwave motors just go into oscillations. Often they will change direction too.

Be a little bit careful with the microwave motors. Because they are such slow motors it is easy to turn the spindle accidently and get a very high voltage across the terminals.

If you are not into fiddly little stuff like the plastic arm on the setup shown then the BBQ motor takes 8 or 10mm square rod that you can take an arc welder to. The rod gives you the option of pushing the louvres from both sides or even several places.

Have a look around at other ways of doing circular to linear motion. Some of the old demonstration models from museums etc. look a lot easier to build. About a week ago I was looking at a way to slide a rack back and forth and come across one I thought looked pretty easy to build. Just searched for the last half hour and can't find it again.

Below is pretty much what I remember. Basically the black is the shaft of the rotiserre motor. The blue is a disc of some description and the red probaly a bit osteel pipe or similar. I just thought it would be easy to make without being too fiddly. I think it is a bit forgiving in the sense that if you don't get the correct amount of linear movement you can just use the same disc but with a hole drilled in another place for the shaft.
I had in mind something simply to roll eggs back and forth so was just going to grab two pieces of cylinder that fit inside each other and weld the shaft to the inside of the inner cylinder.

Are you talking about this idea Denis?

What I would like to know! What is that silver thing that has the 2 red hoses coming from it :?:
Some sort of water heater may be? :?
Or is it just a surface for the water tray to sit on and the hoses are for filling the water tray!

But it does have 2 white wires going to the metal part. :?

Looks like a heater out of a coffee percolator or similar Kowan.

I've got one here at home. I'm keeping it on ice until I come across a small radiator about the size of the ones in car aircons etc. :wink:
Copper pipe or even a coil of polythene might work too. Seems a shame to waste so much of what the element could do the way you have set it up.


Put a rubber grommet or similar where the 240V wires come through the sharp tin wall before you kill someone.

Hi Denis,
going by the image properties it is Kowans unit.

Re the radiator, have a google for water cooling products for PC's you might be suprised.

Regards
Trev

This is my idea for a rolling type turner.

Either use an extremly low geared motor say 1/120 or 1/240 rpm or my thought is a rottiserie motor, limit switches and a control circuit to switch it on and off.

I have already made the actual egg rack and need to start the rest when I can get some time

Trev
