The game rocks or a leg will not tighten.
Legs loose or game wobbles
Cause: Stripped leg bracket threads, a bent leg, or the game dragged by its legs.
Checks
- See whether the leg bolts pull up tight against the bracket.
- Sight down each leg for a bend.
Fix
- Put washers and nuts on the leg bolts inside the cabinet.
- Straighten a bent leg in a vise or replace it; know the maker, game and leg length when ordering, as lengths vary and a few deep solid-state cabinets use different front and rear legs.
- On carpet, set each leveler on a small square of 1/4 in plywood.
