Thanks for the answers. My frames are mounted on a heavy duty table, so the weight is not an issue. I have one of the original B-line frames, before they made legs for them, so you had to bolt them to a sturdy table.
I have never heard of the Bailey, but will check them out. Also the Pfaff, my surger is a Pfaff and I am happy with that, so . . . will let you all know.
