My shop is separate from the house is 20x20. I added 12' overhand on one side to store wood and to do sanding outside. This is where my bowl blanks are now. They are sealed and covered from the sun and weather. At this time there hasn't been a problem but wonder when it starts to freeze will this presents a problem turning blanks when I bring them inside? My shop does freeze inside a few weeks of the year so I built a light bulb warm box that turns on at 38 degrees. I store glues and other products with water in there others get moved to the house. My shop has a propane canon heater that heats the shop up in 30 minutes along with two ceiling heaters.
