Abstract The paper describes the construction, development, and use of the double-end tenoner from the original belt-driven machine with babbitted bearings, with its limited range of cutting stock to length and making tenons, to the present motorized ball-bearing machine, with its broad range of sizing, tenoning, shaping, dadoing, relishing, notching, and dovetailing all rectangular parts in two passes through the machine, and making certain styles of lock joints. It is by far the nearest to a universal use machine yet developed for a production woodworking plant.
