Hello all. Just thought I would pass along my version of a bowling ball vice in case it might be of help to someone I cut just enough of a flat on it to seat a drill press vice, then in a lathe cut a 3/8 groove in the bottom to fit in a 6" PVC glue cap. Mounted cap to board for a solid base so vice can spin on the horizontal, or lifted out of the groove it can be tilted. Dave
