I bought some load leveling casters for my lathe. They are the Zambus type with a threaded stud in the middle. I see some drill a through hole in the foot for the stud to go through and double nut it on top of the foot and then others spend the time to drill/tap a hole in the foot ( like post #6 in this thread http://www.sawmillcreek.org/showthre...ase-for-PM3520 ).
I've put studded casters on lighter weight tools in the past and just drilled clearance holes. Is there and advantage to tapping the hole?
Thanks,
Mike
