This often comes up from people with unheated workshops. Here is my experience:
A few years ago I took a discarded wheel and put it in a pan of water on our back porch. Two weeks of freezing/thawing weather later the wheel was no worse for wear. Then...
My last knife sharpening gig was a grocery store lobby on a snowy day about two weeks ago. I packed hurriedly and put my Tormek T-7 in the car with a full water tray. (Yes, Ken, it was there during the Hartville show.) Weather here has been below zero almost every night since then. Yesterday I made calls on several upholstery shops. At the first one the staff had brought in their knives so I needed the Tormek in addition to my scissor machine. The tray was a solid block of ice.
Fortunately the shop had hot water for tea so I poured in as much as I could. This thawed the tray enough that I could drop and empty it, but the ice still clung to the wheel. Two more trays of hot water and the wheel was ice free and unharmed. I proceeded to sharpen with no problem. BTW, this stop brought in over $200, in case anyone is thinking of a part-time business.
I do not advocate leaving water in the tray nor letting it freeze, but we needn't obsess if we accidentally do.
