When cutting stainless steel keep the cutting speed to a minimum. Stainless steel can harden when heated, then it becomes really easy to break drill bits and saw blades. Cutting fluid, or cutting oil, is a smart move but be sure to clean it all off if you're drilling into something that's supposed to be food safe.
Enough background.

The small whisk will act as a fence to keep the thermometer from making contact with the hot cooking surfaces and the cool ingredients. To keep the thermometer centered in the whisk several ideas were explored. The first was to tie the thermometer's cord into the tip of the whisk where the tines cross over each other but this would put excessive bends into the cord. Another option was to hold it neatly in the center by bending some of the 16gauge galvanized wire used in the Tennis Ball Launcher project but that wire would not be suitable for making food or submersion into water. The chosen idea was to mount the sensor through the metal disc which guides the tines. The sensor and disk would be held in place with 100% silicone sealant.
The first step was to drill a pilot hole through the center of the disc. The next step was to drill a 3/16 inch through the pilot hole. 3/16 inch was slightly larger than the temperature probe which will be passing through this hole.

To position the thermometer a pair of spring-loaded tweezers was inserted to clamp the thermometer and keep it centered. The tines of the whisk also kept the tweezers in place. A liberal amount of silicone was applied since this layer is meant to hold the probe and the whisk disc in place. The cord will be tied through the handle of the whisk.
