I designed my table differently because its tall & narrow & only two castors positioned on the outside of the legs on one side. It tips & then rolls to its new location just like a hand truck / appliance cart. No futzing with leveling feet or cams.
Though my garage floor is very level to begin with. Ymmv.
However my driveway, not so much. I just use a shim.
Didn't have time for that picture Sunday. Maybe today : )
