has anyone ever....
Has anyone ever tried to turn petrified timber?
I managed to "acquire" a few pieces of petrified timber which have been roughly dated at around 30 - 50 million years old. Pictures to follow later.
I am wondering if I need to do anything to help stabalize it? I have not cut it yet so I dont know what the inner structure is like.
My plan was to cut a pen blank, attempt to turn it and then put a coat of CA to first stabalize it while on the lathe.I try and do new things twice.. the first time to see if I can do it.. the second time to see if I like it

I tried a bit of petrified wood once
couldn't cut it with a hacksaw so gave up on that one . I have turned "Zebra stone " successfully which is a layered sedimentary stone , It drill ed and sanded ok , but did most of the turning with a carbide tip on my old metal lathe . Good luck with it though 
cheers John
G'day all !Enjoy your stay !!!

Petrified timber is stone. Hard stone. I doubt it will need stabilising as such, although I suspect it will be quite brittle when completed, and prone to shatter if dropped. I would use a kit that ended up with thick walls to try and be a bit safer. You also of course will need tools that will cut hard stone. Maybe a metal lathe? Diamond?
Good luck!!
PeterThe other day I described to my daughter how to find something in the garage by saying "It's right near my big saw". A few minutes later she came back to ask: "Do you mean the black one, the green one, or the blue one?".

Maybe "petrified" is not quite correct.
The timber I have comes from the middle of the Loy Yang Brown Coal mine. So I am thinking that even though it is "petrified" it may not be as petrified as as it could be.
As I said, the age of this stuff is between 30 - 50 million years old.
Guess I will just have to do some experimenting

I was given an old piece of young coal from Loy Yang at the WWW show in Melb a few years back, from the timber collectors stand. He said it had been carbon dated as 15 Million years old. It is like a dark brown fragile brittle piece of timber. I flooded it with thin CA.
