Replying to Laynak re needle falling out. Your question is a bit old, and I'm new here and unsure of how all this forum stuff works, so I don't know if you'll see this. I, too, have that same problem with a walking foot and/or FMQ foot. Someone mentioned a longer needle clamp screw. They are not easy to find. The last time I checked, SewingPartsOnline no longer carried them, but it might be possible to still find one somewhere out there on the internet. I have the longer screw, but that did not solve the problem. Recently I decided to try wrapping a little bit of waxed dental floss around the threads of the screw. I was able to use the walking foot with no problem. I kept checking the screw, but it never loosened. In the past, the needle would fall out after only a few inches of sewing! The floss might be worth a try. If you came up with a different solution, might you share it?
