Just out of interest, I was in Tasmania, the only source of Huon Pine, a couple of years back. It is a remarkable timber, absolutely beautiful honey colour, never rots etc. BUT, it cannot be logged because of its scarcity and extremely low growth rates. It can only be sourced from salvaged trees from flooded rivers courtesy of the Tasmanian Hydro Electric Scheme. At least that is what I was told by a local.
Most of the original trees were used for shipbuilding when it was found that it did not rot, even underwater! It sure would make for a long lasting TT, if you could get it!
Cheers,
Ian
PS Really impressed with your Jarrah cases, I am thinking of using Tasmanian Oak for mine and getting the heatsink anodised gold.
