So my dad has old wood used to make dollhouses laying around and keeps trying to pawn it off on me for the birds. I'm what many would call overly cautious aka paranoid and if I haven't bought it myself or from a reputable place I won't use it usually. He's saying the wood is fine, but doesn't know what it is and has even cut it and drilled it for me at this point. Does anyone have any more insight on if it's safe or not or even what type of wood it is?
