Robinia pseudoacacia is quite a nice wood to turn , also it often has burrs, it is also sometimes known as Golden oak , it is pretty hard as well , it smells pleasant when green, if you turn something from green wood ( small thin bowl , Bert Marsh style ) the bark sapwood heartwood combination is quite attractive , it is a member of the pea family and smells of peas/ runner beans ! I have turned some pretty big bowls from it in the past , but mostly use it for , lids , finials, eggs , etc I have quite a lot of round rolling pin sized billets of it in my wood store ...... Bodrighwood ... I am pretty sure the wood in your pic is Acacia dealbata ( mimosa ) the name is similar but the tree and wood very different ! .. Terry....
