I found in my limited wood turning with the dup. that if you get too aggressive and try to take off too much that it will grab and dig in and tear. I think it is hard to take tool away from stock quick enough once you make the mistake of being too agressive. You seem to have much more control of a single wood turning tool than the control of the dup. cutter. It being larger and heavier than a single tool, which is what you need, sometimes cause's me to be too aggressive and I can't correct it fast enough so not to dig in and sometimes rip piece out. There is a fine line between the two but practice makes perfect. You want the dup. tool holder to move smoothly and effortlessly across the base but it also can cause you to slide too far in and then you get the big bite at once problem. There is definitely a touch to it. Tool being too sharp will cause the tool to have no resistence when applied to the stock so it just digs in like butter to wood which is soft as far as materials go and if you are not quick enough to pull tool away than you get the big bite, thus the touch. It is only a split second. I know in maching brass and even titianium in some operations, drilling esp., that we always dull the cutting edge of the tool so it does not grab. I still think you want a sharp edge though in wood. Just my 2 cents. Paul;
