Do you have a problem with temperature control and the storage of machines? I know, last summer I kept one machine in the attic and the heat cracked the bobbin fill doughnut and then I wondered what it might be doing to belts etc. so I brought it back in the house. I have 2 huge attics that I could use for storage, but I don't think the cold and heat is good for the machines? Have you had any issues?
