"Odd" timbers for endgrain chopping board
In the "Christmas rush" I'm looking to make a three toned "tumbling blocks" chopping board for the old girl.
In an effort to use up some of the slabs I already have taking up room here, how "good" are poplar, claret ash, yellow box and elm as chopping board timbers if done with end grain? I suspect that the elm would be too soft, but don't really know.
I'd be happy to source more suitable material if something in that list is "bad". I'm trying to avoid it purely on a time basis but don't want to make something shoddy (well, at least this time :q)
