re: Does anyone use pallets?

I have found the preparation work to be more than I bargained for: also, there is an ongoing concern about getting all of the nails out. I’ve ruined both jointer knives and miter saw blades, thinking that I have all of the nails, only to find one that the wood has obscured.
The wood selection is another issue – it used to be that virtually all pallets were oak; recently, I’m seeing more poplar and pine.
