I have a LT-10 Wood-Mizer sawmill. My shop is full of wood I am drying so it can be sold or used to make furniture. The book says it takes 2 years to air-dry. I have looked up the solar kiln designs on youtube and have come up with this. Why on a trailer you ask? So the tax man can not tax me for a outbuilding. New video of it in action next month.
