We have a staircase for a customer and they want it in beech. We are going to be buying the balustrade but were planning on making the treads and risers in house. I have a couple thousand feet of beech (KD) that has been sitting in the shop for quite some time. The customer had asked about one piece treads which I resisted however going through this material we have several very nice boards in the 12"-16" width range. My gut feeling is that itís asking for trouble running one piece but I have never used beech for treads and was hoping for some input. My original plan had been to glue up narrow pieces like a conventional tread.

From contributor Z:
I have used relief cuts in the back of solid treads to enable flattening and remove tension. Add to that gluing with construction adhesive and nailing. If the beech has been stored for years and you have many wide boards that remain flat then thatís a good sign.
