congrats on the grandbaby
my first came on dec 20th, that's all i needed for xmas
if your shop was up here i'd make a room under that mezzanine to keep it heated
i have a 20x30 room in my 50x50 barn that has all of my wood working tools and work benches
it's nice to have a heated shop to go to; with your texas location i'd have the same room with ac going all the time
it's probably equally hard and costly to bring a -15*f room up to temp as it is a 110*f room down to temp
