2. P.elliotti (medium density) 1 1 2 2
1. P. patula 1 1 2 3
5. P.pinaster 2 2 1 2,4
3. P.radiata 1 1-2 2 2
4. P.taeda 1 1 2 2
10. Hevea brasiliensis 2 3 2 2,5

*Nailability
(a) Ease with which nails can be driven
  1. Nails can be driven in with ease
  2. More resistant to nail penetration but can still be nailed without drilling
  3. Unless timber is pre-drilled, nails will not penetrate and will bend over
(b) Ability to take nails without splitting
  1. Practically no tendency to split on nailing
  2. Nailing requires care to avoid splitting
  3. Cannot be nailed near ends or through tongues without splitting, unless pre-drilled
*Nail holding power
  1. Good
  2. Fair
  3. Poor
*Workability
  1. Can be planed, carved or moulded with great ease
  2. Generally workable without difficulty
  3. Wide-ringed timber is somewhat "corky" in texture and inclined to rough up near knots,  but can be worked satisfactorily if tools are sharp. Narrow-ringed timber will fall in class 2
  4. Requires sharp tools to handle considerable hardness, but can be sanded to smooth finish
  5. Clogging of saw teeth by latex occurs during sawing Quality of finish after boring is rough.  Timber dries slowly with serious seasoning defects resulting in recovery loss
