Talk to me about that swan neck tool. I'm not familiar with it.

Hi Ed ,,,,,, swan/goose neck tool is old school technology (the best technology ), designed to eliminate chatter , used allot on planning and shaping machines and for lathe form tools , it works by shifting the point at witch the tool bends , normal tools when put under cutting load will bend and dig into the work , bend a bit more and spring back ,, witch is what you see as chatter on the surface of the work ,, the swan neck tool is designed when under cutting load to deflect AWAY from the work ,,, no dig in = no chatter .
Were only talking about a very small deflection of the tool .

May be a drawing would make things clearer
