I'm currently building a cart for my miter saw. I'm just using cheap 2x4s.
I say"cheap," but these things are nearly twice what they cost a year ago. The lockdowns affected sawmills, too, and that created a lumber shortage.
I browsed a sawmill forum (never been there before, but Google showed me the way) and saw where one guy said it would be eighteen months before lumber prices get back to normal.
Eighteen months. :/
In the meantime, housing prices will climb accordingly. Actually, they already have. Almost everything has risen in price already.
We're going to be feeling the economic pinch of the lockdowns for years to come. Tighten your belts, folks.
