I moved your post out of the old thread and started a new thread. While the general topic of wood is similar, your issue is different from the former so it is best to start a new thread. And more will now see it too.
I am thinking that ash is probably safe as far as the wood itself, if it is thoroughly dry/dead and all bark removed. But this is just a guess.
Here you go. When you have the list of threads in the relevant sectio of the forum, at the top left there is a blue button "New Thread" that you click to start a thread.
While you are in an existing thread, the blue button "Add New Post" will post in that thread.
This is an older thread, you may not receive a response, and could be reviving an old thread. Please consider creating a new thread.
