My DIY egg turner out of pocket cost was only about $15... Sure there are other incidentals that drive the cost higher if you don't have the tools or other misc stuff to build it but for me I only had to purchase the motor and some dowels everything else I had already... And this design be easily scaled up or down to fit the incubator...
The aluminum parts were forged and machined by me from pop cans, using the lost foam casting method... Since it was a simple project I cleaned up the parts using a hack saw, hand file and belt sander vs busing out the milling machine or anything fancy... All the wood besides the dowels was just some scrap plywood and 2x4s I had laying around...
It rolls the eggs 180° one way then back 180°, the travel distance is variable and adjustable on the pivot point where I connect the two arms (within the bounds of the slide distance) so it can be adjusted for different sized eggs if need be...
The foundry to melt the pop cans only cost me about $15 to make and it will be used for other projects so I don't factor in that cost as it's a tool with other purposes... The most expensive part was the $12 bag of Structolite, the steel bowl (crucible) and blower fan were from Goodwill and only a few bucks total... The foundry housing was an empty Freon tank and free... And it runs off wood or charcoal so minimal to no cost there...
