I have been looking at some benchtop mortisers recently and there is something I don't seem to understand. Like many ww machines, many of these machines are very similar, so brand is probably not an important aspect of this, but I have been looking most closely at the Jet JBM-5. If I understand it correctly, the maximum workpiece height is 105mm, or slightly over 4". Now I make mostly decorateve boxes, and I know I will frequently need more height capacity than that even for my relatively small stock. And what about you furniture makers? 4"? I must not undersand this machine. Someone please educate me.
