I offered the following details to ‘Customer Support’ of Anova. They suggested the Anova Community might be interested. I live in Geelong, Australia ; the details are in Metric. I looked at the idea of showing the figures in ‘Imperial’, but the decimal places were mind-boggling. Diameter of metal portion of wand is 60mm = 2.362205 inches. LOL !
I consider my ‘FrankenCooler’, as it is called by Anova, ( aka Coleman 15L esky/cooler - $35 ), a work of art ! ( “German Precision”, if you ask me. )
‘Stepped PVC Pipe Joiner’ was perfect, ( see note below ). Lid of cooler was only 10mm thick. It relies on two plastic walls and ‘air’ in between as the insulator. I cut a 66mm diameter hole thru the two piece roof/lid. I used sandpaper and a tradesman’s replacible blade knife to tweak the soft plastic into the right diameter for the Outer lid hole at 74mm ; which only took 30 mins. The ‘Step’ on pipe joiner sat perfectly inside the lid cavity. The Anova Precision also sits perfectly on the inner ‘step’ of the pipe joiner. The joiner was cut, so it would only protrude 5mm above the lid of the cooler.
It took me 60 mins, of gently hand sanding, with 240 grit wet & dry sandpaper, ( remember to use water as a lubricant ), to make the inner hole of the pipe 61mm in diameter, and an absolutely perfect sleeve for the Anova Precision. Hole is on hinge side of the plastic cooler. I can’t use the official Anova black screw clamp. We will see if there is any vibrations, that will damage the cooker, while cooking.
I used two part epoxy glue from America called ‘PC Super Epoxy’, ( a brilliant product ), to permanently glue and seal the pipe into the cooler lid. Glue was used inside lid cavity and on both sides of the 10 mm deep hole.
The ‘Anova WiFi Precision’, when installed, hangs 45mm above the inside base. It requires 5 litres of water inside the cooler, to meet minimum water level for this model of Sous Vide wand/stick.
My first cooking attempt was brilliant. No vibrations from the extremely well balanced Anova wand/stick. Walls of cooler remained at room temperature during the 3 hour cooking session, and minimal heat loss thru the lid/roof, which was warm to the touch. The vent on the back of the Anova is not blocked, which is good for cooling the wand, and it prevents my FrankenCooler becoming a pressure cooker. There was also no hint of water evaporation or condensation on the outside of cooler.
NOTE : Stepped Pipe Joiner, ( $3.45 ). One end has an internal diameter of 60mm, and externally 65mm. The other end has an internal diameter of 65 mm, and externally 73mm. To be honest, the entire pipe is tapered slightly, internally. More like 59.5mm ; then 60.5mm and 64.5mm in the middle ; then 65.5mm.
NOTE : My next step is to go back to the hardware store and try and find a Rubber Bung to fill the hole. Then the Coleman can be used as a genuine ‘cooler’.
P.S. Added bonus of ‘Sous Vide’. Water stays warm in the cooler, and can be used to wash the dishes.
