A machine tool defining a first direction and comprising;

• a base;
• a first and a second stationary rail connected to said base, each of said first and second stationary rails having a first end and a second end;
• a first and a second movable rail slidingly disposed on said first and second stationary rails, respectively, said first movable rail being generally equal in length to said first stationary rail and being movable to a first position where a first portion of said first movable rail extends beyond said first end of said first stationary rail and to a second position where a second portion of said first movable rail extends beyond said second end of said first stationary rail, said second movable generally equal in length to said second stationary rail and being movable to a first position where a first portion of said second movable rail extends beyond said first end of said second stationary rail and to a second position where a second portion of said second movable rail extends beyond said second end of said second stationary rail;
• a first rack provided on one of said first stationary and said first movable rails;
• a second rack provided on one of said second stationary and said second movable rails;
• a pinion assembly including a shaft and a first and a second pinion gear matingly engaging said first and second racks, respectively;
• and
• a fence positionable on said first and second movable rails such that when said fence is positioned on said first portion of said first movable rail and said first portion of said first movable rail is extending beyond said first end of said first stationary rail, said fence does not overlap said base, and when said fence is positioned on said second portion of said first movable rail and said second portion of said first movable rail is extending beyond said second end of said first stationary rail, said fence does not overlap said base.
