SewpahDewpah,
Paperclips the larval forum of clothes hangers ............... I believe it. LOL
Just for giggles and grins check your Brother CS6000i for a tortoise and hare switch. Our Bernina 930 has a two speed on / off switch.
First position is normal, second for slow speed. I've also read that some machines have this switch on the foot controller. It 's just a thought.
