Steering wheel form an old ship perhaps??

[SmallFry]

Sometimes you see reproduction ones in some of the home decor type stores, probably not 4' by 4' though. You could create a ships wheel design out of some plywood or something with a jigsaw. Not the same I know, but...

Reminds me of a (bad) joke: A pirate goes into a bar with a ship's wheel stuck to the front of his pants. The barman says, "I'm sorry to bring this up, but you appear to have a ships wheel stuck to your pants." "Arrrg, I know", replies the pirate, "it's drivin' me nuts!"

Sorry...
