Yes sadly, the wood are old bleacher seats and they were all cut up for a charity sale from a high school built in the 50's. Why will it be hard on my wood working equipment ? Flooring was my only idea for it also.I have made a few cutting boards out of it even though it not a very hard wood it seem to work fine in the home.GeorgeC said:Do you really mean 19 "inches" long?
If it is real heartwood it makes great kindling. It will also be very hard on any wood working equipment.
If you can machine it, then it would probably make a great wood floor.
