For most domestic machines that would be a vertical spool pin instead of horizontal and on my LA it is exactly the opposite (a horizontal spool pin). I would not be able to run this thread on my Bernina without improvising something but I have run it on my LA as I have a special side spindle just for stack wound threads. It will easily stretch out of shape if it is not loaded properly and then it will break.
