Hi Good news that you have retired. Lots of time to carve coming up.
I found a “lazy susan” at kitchen store. Usually around 10-15$. Check if it turn easily when you buy it.
Re basswood. Yes the northern basswood is easier to carve du to it grows.
Re spraying. Yes this is a good solution, half water and half alcohol, when you feel your wood is very dry.
Keep carving makes you a better carver.
