Be careful when buying a used board stretcher as most of the used ones are either three phase, or 220 volts, 50 hertz. Won't work in most of our shops. You will need an expensive converter. Probably cheaper to buy the right sized board the first time. Then cut it to the wrong length. This why I always cut my longest pieces first. Then I can use "goofs" to cut shorter pieces from. Oh no, my secret is out.
