NorfolkPine2.jpgNorfolkPine.jpgI have recently returned from a holiday on Norfolk Island. There were a couple of woodturners turning the native Norfolk Island Pine producing mainly small items for the tourist trade.
A few days after visiting one of the woodturners (as part of an organised tour) I noticed this slab in one of the island's museum.
When Capt. Cook discovered Norfolk Island in 1774, he thought the native pine tree would be ideal for ship's masts. This was found to be incorrect. The reason being shown in this cross-section. The long dark 'knots' radiating out from the centre are very dense, very hard and are part of the branch structure of the tree. These occur every 1 - 2 metres along the lenght of the trunk causing structural weakness.This section was about 750mm in diameter.
I did not see any items made from these "knots'. although they can be in excess of 500mm in length and up to 80mm or more in diameter. I also wonder about the stability of the pine given the large 'crack' in this section. Unfortunately I did not get time to go back and discuss this with the local turner.
Has anyone turned these 'knots' or had experience with turning Norfolk Island Pine? What was your experience?
Thanks
Bob
