Thanks Miz Johnny,
The one I saw was not screwed in, it had two posts that fit into the two holes on the bed of the machine. Everything was smooth so as to not catch on anything.
I have a FW but I am reluctant to try to quilt with it.I think the 66 is going to be my "quilter". Billy mentioned that he quilts with his, so I'm hoping I can do the same with mine.
:-D
