Every fitter has a stack of offcuts too small to use and too big to throw away without a twinge of guilt. Some waste is unavoidable — but most of it comes from a handful of repeatable mistakes, not bad luck.
1Nesting by eye instead of by algorithm
Laying out parts on a sheet by hand is slow and leaves gaps a proper bin-packing pass would have caught. A 58% yield by eye is common; a real nesting algorithm regularly gets the same job into the high 70s or 80s.
2Not grouping similar sizes before cutting
Ten pieces that are all within a few millimetres of each other are ten separate cuts unless you merge them first. Cutting them all at the largest size and trimming down wastes far less board than treating each as unique.
A sheet of board doesn't care how busy your week was — it costs the same either way.
3Ignoring grain direction until you're at the saw
Grain-matched carcases and doors need every long piece running the same way. Deciding that after you've already nested the sheet means re-nesting from scratch — decide it up front and lock it in.
4Cutting doors and carcase parts from the same sheet plan
Doors and drawer fronts are frequently a different finish or colour to the carcase. Nesting them together forces compromises on both. Split them and each nests tighter.
5No record of what actually got wasted
If you don't track yield per job, you can't tell whether a supplier's board width, a client's odd cabinet size, or your own layout habits are the real cost driver. Even a rough yield percentage per job is enough to spot a pattern.
Flasta Cut's sheet layout does the nesting, grain-lock, and yield percentage for you automatically — worth a look if you're still doing step one by hand.
