two-piece extension- ?

[evergruven]

basically, I'm interested in commissioning a 54" cue with a two-piece extension, each piece being three inches long=6" total
wondering any potential implications from a cuemaker's point of view? how might you build it? thanks-

hey dave, thanks for chiming in..looks good! I like how the rubber bumper fits into the joint.
can you say how long the total extension is and how much it weighs?
