This is.what I have. It doesn't have a model number on it. I have a 430.

I am currently sewing on a 450 and I have the same walking foot. Mine looks exactly like yours except the arm that goes on the needle bar looks black where mine is silver. To be clear...you are putting the fork on so the screw for the needle is in the middle of the 2 forks? I don't understand it could slip off in that case unless there is a defect in the foot. Also, the needle does indeed fall in front of the bar on the foot just as yours does. Try not to get upset, I am sure your dealer will come up with a fix. So sorry.

Here are some pics of how mine looks. Also the box from mine.

Yes, that is how I am putting the arm, around the screw, not on top of it like other brands.

Your needle hits in front, not in the hole? The picture on the instructions shows it IN the hole.

Mine is not easy to get on. Seems I have to work at 3 things at once - hold the presser foot lever up (so it goes up a little higher than normal), slide the walking foot to the correct postion under it and also get the fork in the right position on the bar. Finally flip the lever down to lock the foot in place.

Don't have a bernina, but in your side view picture it seems odd that the foot is resting on the grey plastic machine casing. It does seem like it should be more forward...

I uploaded a video to show how.the.arm falls off.

Here is the picture from the instructions that shows the needle in the hole, not in front of it.

I'm so confused- it worked PERFECTLY for binding half the side of a quilt (the starting side), but as soon as I broke the thread so I could turn the corner, it messed up and I can't get it to work again.

Yes, the pics are up now, hope that helps.

[quote=nursie76]Thank you for posting the pictures- I still think the needle is hitting in the wrong place, it looks like yours is in front of the OPEN sole. I am using the closed sole, so it should be sitting further back. Your arm also comes much more around the needle bar than mine does, hence why mine is falling off (see video). It is like the cone is in the wrong place to connect it to the machine.

Take it and your machine to the shop where you purchased the foot. They should have a record of it, especially since you have already talked to him about it. If it is defective, they will exchange it for you.

Yeah, that appears to be what I'm going to have to do. Which means I have to go back to binding without it, because I can only get to the shop during the weekends, since they have only work-day hours during the week, and it is an hour away :( I have to get this quilt done. They are already closed for the day.


I am so upset. A $200 foot should practically sew for itself- it should not be acting like this!
