A configurable butt for a cue stick comprising a body comprising an elongate chamber having an internal thread and a movable weight coaxially located within the elongate chamber and having an external thread, the movable weight being threadingly coupled to the internal thread of the elongate chamber. An internal shaft extends through the movable weight is adapted to rotate the movable weight within the internally threaded chamber thereby causing the movable weight to move between respective ends of the elongate chamber by virtue of the threaded coupling for adjusting a centre of gravity of the cue stick. An indicator arrangement is coupled to the internal shaft and adapted to provide an indicate of the location of the movable weight within the elongate chamber.

A mast lift includes a base and a telescoping mast coupled with the base and extending upward from the base. The telescoping mast has a support section fixed to the base and a movable section movably connected and displaceable relative to the support section between a retracted position and an extended position. A top cap is secured to the movable section, and a platform is supported by the top cap and the movable section. A gas strut acts between the support section and the movable section and biases the movable section toward the extended position. A threaded driving rod is connected between the top cap and the base and extends through a fixed nut assembly.
