Singer Presser Foot Adapter
I'm in the process of designing and fabricating an adapter for my Singer 31-15 that would allow me to use any attachment that can fit onto the presser foot of a 31-15. For example, I found a zig-zag and button hole attachment for a Singer Lockstitch at an antiques store. These attachments fit neatly onto the presser foot but do not line up with the needle. Therefore I've designed a small linkage that articulates allowing for the attachment to be lined up and used as designed.
My questions:
Have I overlooked a device that already accomplishes this task?
If another device doesn't already exist, doesn't anyone else want/need one for their old Singer?
