Hi Cliff
The Queensland Mahogany is Eucalyptus Resinfera.
They say it makes a great construction timber and good for wharfs. Guitars????
It is about the same weight as mahogany and maybe bit harder.
I got it cheap to make a table decided a guitar might be worth a try being a rank amateur.
It has a nice light red colour
I will put my build in a diary shortly. Been slack.
