loose joints

im trying to make a physics based game with revolute joints to simulate a linkage between bars...but the joints are "loose" as in they don't act like pinned joints...there is "slop" in them as if they were connected by springs instead of fixed position joints...

any ideas?

thanks

danno55 looked through your capx, it all looks great. Perhaps I misunderstood what you are trying to achieve, but they are three linked bars all operating under the physics environment. I did not get the slop or springs reference.
