for simple to much more complex work (tips) to under the wrap cue extensions etc. I recommend STRONGLY a man named Rolando Aravena who 3 days a week can be found working at Amterdam Billiards.
He has workde on my Ginas, Mottey, bobby Hunter and countless others including shaft work. His work in my opinion is impeccable, and anything short of MAJOR serious work I let him do everything. Anything too major, I send the cue back t the original maker.
Hope this helps.
He can be contacted at (518) 583-9549 his shop
or thurs, fri or sat at (212) 496-8180
He also works very quickly.
