The Sykes-Pickavant ball joint separator as modified. The bolt has to be screwed in so far for the MGB ball joints that it starts making an angle with the lower arm it is bearing on. Despite its heavy construction I could feel the bending forces building up and feared it might shatter, just inches from my face. So I built-up the end of the lower arm so that as the bolt was screwed in, and due to the angles involved moves slightly down the arm from the hinge, its business end is always pretty close to a right-angle with the bit of the arm it is bearing on.
