Work your magic on this (once you finish your book and are bored)
Each shelf will be 37 inches long, 25 inches wide (capacity is 288 eggs on 6 12x12 trays)
The shelves will be 1.5x1.5x0.125 aluminum angle bar, pop riveted.
two pieces of angle bar will also run down the middle. Length wise to support the tray. The 1.375” internal lip of the angle bar will support the feet of the egg trays
A woven aluminum grill will be inside each shelf to ensure all size trays will have somewhere to rest.
The trays will attach to a 1” upright square bar that will run from floor to ceiling on either side of the bator. The actuator shaft will attach to the top shelf through the central bar.
We will use 2” x ¼” stainless machine screw with ¼” nylon spacers to attach all shelves except at the turner actuator
There will be four trays, 12” apart, joined by 1x0.125” flat bar- one on each side so they travel in unison
The bottom tray, when flat, will be 18” from the floor of the bator and the top shelf will be 18” from the top of the bator.
The actuator is designed so that when it is powered, it turns 90 degrees and remains in that position until the power is cut. It has a high powered spring that will slowly return the device to the no power position. A pin will be used to stop the trays at level when powered off and trays begin traveling back to the no-power position. Once the pin is removed, the trays will continue their path. External limit switches are not required.
The heat source will be 2 x 250w ceramic heaters with cowlings to direct airflow through the fins from 4” 220v case fans. There will be a cutoff at 45C on each heater should the fans fail so they don’t get super-hot and cause a fire. The “egg area” of the bator will have a 46.5” x 26.25” floor plan. Its height will be 72” internally. The heating area will be at the rear. Air will enter from the upper 12” of the rear of the bator, into to square ducts 6.5” x 6.5” housing a 6” 110v duct fan. With the heat source and fan in the column. The areas not used for airflow will be isolated from the bator. There will be 2 6x14” vents at the lower 16” of the rear of the bator for the heated air to circulate. Lower vents will have adjustable diffusers.
With a 4” kick plate, and using ¾“ marine ply, the total dimensions will be 79 inches tall, 48” wide and 36” deep.
There will be a 2” vent above the duct fan to draw in fresh air in each duct shaft.
Prior to installation of turner, the internal surfaces of the plywood will be coated with a thin scrape of non-toxic 2 part marine epoxy and painted with a water based enamel to create a waterproof, cleanable surface.
Exterior will be painted with a water base enamel.
Piano hinges will be used on doors and two steamer trunk catches on the doors.
