How to adjust the straight stitch on a Bernina 117 zigzag sewing machine.

I use a dial indicator mounted on a flexible arm magnetic base to adjust the straight stitch on a zigzag Bernina 117. I was getting a slight zigzag while the machine was set to straight stitch. A dial indicator is a basic measuring tool that has a plunger on one end. As the plunger moves in and out of the indicator, a needle on the dial shows the measurement of the distance. Each line on this dial indicates .001 of an inch (one thousandth of inch = .0254mm). After mounting the indicator on to the flexible arm I set the plunger against the block that holds the needle bar, depressing it until I get a reading on the dial. I then zero the dial by rotating the face. As the needle bar moves back and forth it depresses the plunger causing the needle on the dial to move. Using a 5mm screwdriver I loosen the limit stop and slide it to the center of the shaft. Then I turn the zigzag lever to maximum zigzag to get access to the adjustment screw. Then I loosen the screw with a 2mm screwdriver and then move the zigzag lever VERY SLIGHTLY, then tighten screw and move the zigzag lever back to straight stitch. Rotate the hand wheel and watch the dial indicator if the needle moves more than it did when I started I readjust moving the zigzag lever in opposite direction after loosing the adjustment screw. I repeat this adjustment procedure several times until there is very little movement of the needle on the dial indicator. I was able get the movement down to less than one thousandth of an inch. Then I readjust the limit stop so that the zigzag lever can move between straight stitch and full zigzag.

This is really interesting, thank you! My Bernina 730 does the same, it's very annoying.

I just got a KL 117 with a few issues. First, I need to figure out how to adjust the needle bar to center the needle in the stitch hole from left to right. It centered front to back. It sews a very straight stitch, but the needle is not in the middle of the stitch hole and is slightly off to the left of center (1-2mm). Also, the "Needle Position Lever" will not go to the right side, it only flips between left and near middle. Any advice? Thanks!!

Try turning the knob on the back of the machine.

@@philipbrutz2175 That's the Needle Position Lever, but it won't turn properly as I mention above. It only goes left to almost center. It will not put the needle to the right.
