No trestles to rest/level work top on prior to cutting. Made do with a single metal step. Did not use sticky tape along saw lines to prevent chipping of laminate when cutting. As a result, the laminate surface is not cleanly cut, leaving tiny chips. Did not trim off lower edge of laminate strip used to cover 2 exposed sawn ends - I had to cut off 4mm myself. The exposed cut end of the 'L' shape is not straight - deviation of 3mm at the centre point. But friendly/helpful and arrived on time.
