Check the base for bends, separated
welds, cracks, corrosion, damaged,

or other evidence of mishandling.
Check column and saddle for bends,
corrosion, missing teeth on the rack or
excessive wear.
Pawl should not be visibly bent or have
any visible cracks.

the reliability of the stand, it should be
replaced.

breaks, bends,
cracks, corrosion,
