Quoted from Lethal_Inc:Has anybody actually confirmed that tightening the leg bolts too tight might be the problem? There should be a torque setting.
The leg bolts apply equal force inside and outside the cabinet, via the plates and legs. Overtorqueing will strip your threads long before any cabinet damage.
It's not a factor in cabinet splitting. And the standard plates aren't new, I have machines from the 60s & 70s that use them and aren't splitting.
