I've got two sets of these plus extra delrin ends. It is the best money I've spent on any jig as far as making the building of a well indexed cue with either points or inlays possible. I believe it is probably the best jig, as far as ease of use, dependability and filling a need for builders who have a reason for moving a cue or forearm before completion. It is the sole reason that now I can build a four pointed, half-splice cue where, if I desire, the points actually touch each other at the A-joint. The cue or prong set-up can be broke down and re-indexed dozens of times, if needed and re-indexed again perfectly in both axial and linear directions. It's the best thing that ever came out of Lee's shop in my opinion.
