the joint collar on the univeral smart shaft is threaded in so you can remove it and insert a different joint collar for a different cue so it makes it univeral.. lets say one cue is a 5/16-14 and another is unilock.. works like a champ.. each smart shaft comes with 1 joint of your choice.. and i think retail on each other joint is about $30 bux retail..
i had the idea of getting studs that where 5/16 18 on one end and 5/16 14 on other so i could use the ob-1 on both my cues, the ob-1 is 5/16 14 . and i want to use it on my huebler also,, will this work ? ,,,, i think it will
