Hey Steve,
I am an aussie currently in Canada Timber Framing and I am returning to Australia in May next year to continue Timber Framing .
I grew up in Walcha New England where abouts are you? I cant promise anything but my first job when I return might be a house in Bonalbo north east of Tenterfield we are currently waiting for the drawings so that I can design some timber frame into it. If this ever eventuated I would be happy to show you a few tricks of the trade to help you out.And if it doesnt there will be others.
How are you going finding large timber and what sought of timber are you thinking of using? we have some nice hardwoods down there.
If I can help in any way give me a yell.
Rob
