Admittedly, the part is already quite shaky and I was initially a bit shocked when I had set it a little further and went with 140 on a slightly undulating highway because the part has started well with swing.
That could be but leave quickly by having played around something on angle, tilted piece then approximated bit there, etc. have now found a good Poistion where nothing swings like the pendulum and that I can for this ridiculous price live very well.
