If you are asking this question, it would suggest that you are not an experienced machinist that is able to work around the mods needed and save maybe a few dollars. So I would suggest going to cuesmith.com or midamericapool.com and buying one already modified for cue repairs. If you are inexperienced it will save you time and money. But both of these gentlemen will give you the support that you will need. Both are easily reachable and highly knowledgeable. Your first stop should be Chris' cue making book. There is no better starting point, including this website (which is more useful when you have developed the necessary basic skills). An inexperienced beginner needs all the knowledge and correct equipment to begin with because...There are no second chances in cue repair.
