Our woodenware is manufactured from hand selected Ponderosa pine. Each board has been carefully moisture-metered to assure its proper moisture content before it is precision milled into the finished product. All our supers have “pre-drilled” holes for nails to prevent splitting during assembly. Handholds are taper cut for easy gripping – Moisture Metered before cutting to prevent warping – Uniform Interlocking Joints for strength – Ponderosa Pine from the Northwest, the best wood for the job – Uniform Frame Rests provides the proper “Bee Space” – Nails included, not assembled. Paint the outside of the super only.
