I searched the world found a Siberian Wolley Mammoth Molar. Phoned around three countries ,bought one on recommendation from the USA. Delivered in three weeks. Wilma and I joined the Canberra Lapidary Club. This gives me use of Diamond Saws etc,no Stone Lathe. I bought the nearest Artu Drill 3/8. I cut the Molar with a small bandsaw ,clean as. Drilled the blank with the 3/8 Artu Bit then normal 27/64 metal drill. Normal preparation of the blank. Turned over three hours using a Carbide Square bit using the four sides, sharpened every hour on a Diamond File. Terribly slow process of turning, slow and sure. This pen kit is very fine at the tip and top, took it down as far as I dared.The blank had been stabilised and the light bands are pure silica,all very treacherous.
The conclusion for me was never use water with these teeth,this shared before I started cutting and turning. A business in town run by a Miner and Gem and Stone specialist has 6 staff in Thailand and Bali who only use wood lathes and normal tools. I can now relax and get some sleep.
