TT I thought i'd posted this a couple of days back, mustn't of took.
I showed the pics to a couple of guys at work that have milled east coast Aussie eucalypt, can't really help but can probably rule out Yellow, White, Grey Box, Scrub Box, Blue Gum, Spotted Gum, Black Butt and River Red Gum. It maybe Tallow Wood, Stringy Bark or at a slim chance Iron Bark.
On the West coast there is Karri and Jarrah but I don't know much about them.
Don't mind the axes I have been directed to sell my collection and these pics are for ebay
, they show a table I made from 80yr old Stringy Bark fence posts I adzed down and dressed, the bottom pic has a stool made of rough Yellow Box(very cramky grained) from old cattle yard rails, if you look close you might makeout the growth rings on the tenons.
As mentioned our Euc's don't display anual growth rings, some seasons you might get a few others none, apart from the Blue Gum i don't know of any formulaes to tell the age.
If the samples were Box or IronBark you couldn't get a nail through it without a pilot hole, stringy barks not quite as dense and has a straighter grain.
