A rip saw, an under over planer ( neither have to be large ) - these will cut and dress the sections of the chopping boards.
Clamps to glue the sections together
A small rotary drum sander - you can then feed the "rough" glued ( full width ) board through and produce a perfectly flat and finished surface - ready to oil
That's all you need to produce as many boards as you like, in the shortest time.
What do you think ?
