Already did that thanks Birchy, from the other search I did I found that another option was bowl blanks so looked at that as well, got a number of places to call mainly places like sawmills that cut the blanks themselves. Couple are mentioned in that link you have posted thanks.
m_c I did think about searching for firewood suppliers but then thought that what they would have & sell would be to small a diameter, maybe completely wrong about that lol.
