Ok so I am currently looking at two different shapers that do not have reverse. Both are three phase machines and I have checked into adding a switch. It is going to cost me 500ish for switch. Square D barrel switch or drum switch. Have any of you done this ? One other question ,if one does then is a concern to have a "locknut"or shaped washer on the spindle ? Shaper one is a Ema . Shaper two is a Wadkin. Both are solid capable machines with 1.25'' spindles and other than not having capabilities to switch spindle directions are everything I need. Is this something that I absolutely need? I know that I want it. Mike.
