Timber conversion, 3 marks

One disadvantage of quarter sawing compared with through-and-through sawing is that it…

  1. Gives boards that cup badly
  2. Shows no attractive grain figure
  3. Is slower and makes more waste
Show the answer

Is slower and makes more waste

The log must be turned several times, which takes more labour, and it gives narrower boards and more waste. So quarter-sawn timber costs more.
