I tried that but the plank would randomly spin when positioned to mouse x, y.

I'm not sure if I understood, but that wouldn't solve much.
On the other hand, you gave me an idea.
What if I would keep that initial instance (usually I would have it destroyed) and rotate that as the player chooses the angle at which to spawn the new object. With that the initial object would be at the same angle as the spawned object would need to be.
UPDATE: apparently the current angle of the initial object doesn't matter, but the initial angle.
It would be really nice to have a "at angle" option in the Create object action.
