The pressure foot has come off the arm. i think that a bolt or screw hold it in place. where can i buy or get this item

The foot always has an adjustment screw that is above the foot. Follow the foot arm directly above the foot. It will have a little screw above the foot that turns. You may have to open the front of the machine where you will see a small numbered gadget; round or star shaped usually. Anyway, this will have to be adjusted by the sewing individual. If it can't seem to be adjusted to hold the fabric the foot arm length needs to be adjusted by a repairman. Anyway, go to utube and type "adjust sewing foot pressure" for an easy lesson.

The pressure foot is only made to push down on the material, not the feed dogs. If you put it too low it will destroy the feed dogs and the pressure foot as well as the material.
1. To adjust, lower the pressure of the pressure foot as much as you can.
2. Place a thick piece of material under the foot. Turn the hand wheel until the feed dogs are up.
3. The pressure foot rod has a screw that holds it into place. You will adjust the rod by moving it up and down until there is a small amount of pressure on the material. Tighten the screw and try your machine without a needle to see if the material will move. Now, try other thicknesses of material. The rod may need to be slightly adjusted a small amount to get it "just right".
4. PUT IN NEEDLE AND CHECK FOR ALIGNMENT TO THE HOLE. (DANGER IF NOT ALIGNED).

1. Take the top off.
2. Look at the back of the tension mechanism while you move the pressure foot lever.
3. You will see an arm go up against the back of the tension mechanism. This pushes the tension disc forward to release pressure.
4. Yours isn't doing this. The screw that holds the tension mechanism is likely to be loose.
5. Pull the foot in the up position.
6. Unscrew the tension mechanism a little more. Now push in on the mechanism and tighten.
7. Now you can try to see if this has worked.

IT SOUNDS LIKE THE FOOT PRESSURE IS TOO TIGHT. AT THE TOP OF THE MACHINE THERE IS USUALLY AN ADJUSTMENT. LOOSEN THIS UP AND TRY THAT WAY. IF THIS DOESN'T WORK YOU MAY NEED TO ADJUST OR HAVE ADJUSTED THE ARM THAT HOLDS THE FOOT. IT SHOULD BE VERY CLOSE TO THE FEED DOGS BUT NOT TOUCHING. LOOK FOR THE SCREW THAT HOLDS THE ARM AND PLACE SOMETHING UNDER THE FOOT TO HOLD IT UP JUST SLIGHTLY. THEN LOOSEN THE SCREW AND MOVE THE ARM UNTIL IT IS ADJUSTED AS IT SHOULD BE. YOU MAY WANT TO GO TO A SHOP TO HAVE IT ADJUSTED OR HAVE A FRIEND THAT IS MECHANICAL AND HE WILL FIND IT EASY TO ADJUST.

usually a gathering foot or ruffler fits on like one would fit an old style foot. Unscrew the thumb screw that holds the snap on foot holder.... and place your foot making sure the needle holder thumb screw holds the lever on the other side. And tighten the thumb screw to hold on the foot.

Good luck.

I'm assuming that this is a generic style walking foot for low shank machines and it will fit your Elna?
To attach it, you will see a long lever arm at the front of the foot and the little curved bracket at the back of the foot.

Remove your usual foot and the clip on foot holder by undoing the thumb screw. Now fit the walking foot on instead by putting the lever arm around the needle bar and the curved bracket around the pressure bar and then putting the thumb screw back into place and screw up tight to hold the foot in place. Now lower the pressure foot and manually wind your machine forward a few stitches. As the needle bar goes up and down, it should move the long lever arm too which works the walking foot teeth gripping the top layer of fabric with each stitch.

Trust this helps.

Hi. I believe your machine has a snap-on pressure foot. I've posted pictures of snap-on pressure feet at www.robbiesews.blogspot.com; just look for the 'pressure foot' tag or search the site for pressure feet and you shouldn't have any problem finding that post.

Anyway, there is an adapter (called an 'ankle') at the end of the 'long iron piece that lowers and raises the foot' (excellent description, BTW). The ankle attaches to that piece with a small thumb screw. With the ankle in place, you just lower the ankle onto the catch on the pressure foot.

You can also use regular low-shank feet on your machine. First, remove the ankle. The regular low-shank feet will attach to the raiser bar with that same thumb screw that holds the ankle in place.

You really should get a replacement manual for your machine. I found manuals for Simplicity sewing machines at http://www.sewingpartsonline.com/simplicity-sewing-machine-instruction-manuals.aspx.

Hope this helps!

You will have to get a new Trigger Release Shank

If your SU is an Air Electronic model i.e. 80's model, Elna didn't make a walking foot to fit. However, if you've got a walking foot that is the same height from sole plate to the screw fitting as a standard Elna foot then you could give it a try. The walking foot connects to the presser bar with a screw but the needle bar also needs to hook into a secondary lever on the side of the walking foot to make the foot actually move. Probably sounds very confusing . Check the movement of the foot manually by hand turning the fly wheel to see how it works before you actually use with the motor to minimise any problems if the foot doesn't fit.

Also you'll probably only be able to do straight stitch with this foot due to the clearance around the needle plate.

The needle shaft sticks to the curved arm and won't come down because a piece of plastic, about an eighth of an inch thick had broken from age. It prevented the shaft from staying up on the needle arm. Open the cover, try to stitch decorative stitch and see what I mean. Purchase a package of 4-10 by 1/2 nut and bolt pack. Screw the nut all the way onto the bolt. Using needle-nosed plyers, Carefully bend the curved arm slightly, and place bolt into the hole on the top of the needle shaft. Nut will keep it in place. Lowering the needle shaft using wheel, carefully bend arm back in place. Try decorative stitch. It should work. It does for me.
