Thanks for the nice comments but might have to cut another sign.
After I finished brushing one coat of Tung oil on it I decided to used a piece of thin wire to suspend it to dry, guess what, the bent wire straight itself out and the plaque fell on the cement floor, broke in 6 pieces (will not go into what came out of my mouth at that time) I thing it can be glue back, because the break was clean and the wood is oak.
Will buy some instant wood clue and give it a shot if it does not work, will find another piece of wood and another 4 hours on the scroll saw will do it.
