Needle timing. Ihave a Model Ese2 . I have a quarter inch foot with a very tiny hole for the needle. I forgot to change the needle setting to the middle and broke my needle. They say that threw off my needle timing. I would like to know how to repair this myself since I have done it before and it cost $40 every time I have it repaired.

We need to know what machine you have before we can offer any suggestions.

FWIW, I mark a scant 1/4" to the right of my needle point and mark it with painter's tape. Then I don't have to mess with changing the needle position.

Look at page 62 of the manual:

Unless your machine has multiple minute needle positions, you probably won't get a perfect scant 1/4 inch with that method. I haven't found a 1/4" foot or a needle position that gives a perfect scant 1/4".

Instead, look at setting a mark on the sewing machine surface that measures a scant 1/4" from the needle point. I use a ruler and set the needle point on a scant 1/4" from the ruler edge, then use painter's tape or something similar to mark the guide where the fabric edge will set.

Or, the fastest and easiest guide is a pad of 3X5 Post-It Notes. Measure a scant 1/4" from the needle point, remove the back sheet of a Post-It pad, and then align the sticky edge of the pad to the scant 1/4". Instant fabric guide that is easy to remove and is reusable.

How to Mark Scant Quarter Inch Seam with Painters Tape to Your Sewing...

If your machine is considered a "quilting" machine, it may have a 1/4" foot included. However, most machines do not include the 1/4" foot. A quarter inch foot looks a lot like a basic presser foot except the edge should be 1/4" away from the needle.

FWIW, you can achieve a 1/4" seam by placing a ruler under the presser foot and gently manually lowering the needle point until it rests on the ruler's 1/4" mark. The ruler's edge would then be exactly 1/4" away from the needle. You can place a piece of painter's tape (on the sewing surface) adjacent to the ruler edge and this would serve as your quarter inch guide.

Even if you decide to purchase a quarter inch foot, in my experience, none of them provide the "scant quarter inch" seam for piecing. Other than marking a scant quarter inch measurement on your sewing machine, achieving it will usually take some testing to determine what constitutes a scant quarter inch on your machine.

Probably the 1/4" quilting foot. It is designed so it's easier to sew a scant 1/4" seam by aligning the fabric edge to the foot's edge, which is what you need for piecing. Of course, to get it perfectly accurate, you may need to move the needle slightly or figure out where exactly 1/4" from the needle falls on your machine (important if you will be matching points in your piecing). Measuring 1/4" from the needle and then marking with a strip of painter's tape works for some.

Generally, it is assumed that you set the needle at the center position and align the fabric edge with the edge of the 1/4" foot. However, there is a degree of variance from one machine to another, so it is a matter of testing your machine. For quilt piecing, most often the sewist will have to adjust the fabric position to stitch a "teensy" bit less than the edge of the 1/4" foot. Again, it is a matter of testing your machine and adjusting your fabric. For those with computerized machines with many needle position settings, some sewists are able to adjust the needle one needle position to the right to attain the "perfect" quarter inch.

Sounds like you need the manual. This will give you a lot of basic information on how to use your machine. Please read the book all the way through.

Also, check that you are using the proper presser foot for the stitch you have selected, ie do not use a zig-zag stitch with an embroidery presser foot that has only a tiny hole for the needle. Be sure you are installing the needle correctly. If the needle is backward, it could be hitting. When a needle hits something solid, it could knock the machine out of time, requiring a service call. Before running the machine, you can check whether the needle will clear by hand-rotating the handwheel one full cycle. If the needle strikes something, at least you can stop before it breaks or causes further damage.

Either you have the wrong foot installed or your stitch setting is incorrect. Dial in a narrower setting. You may have a zig-zag setting without the zig-zag foot attachment, or your "width" dial is too wide for the foot's hole. Slowing turn the wheel and watch where the needle penetrates the foot hole. A collision at that point will break your needle every time!

broken needles can happen if you are pulling the fabric through rather thsn letting feed dogs move it, or if stitch setting needs a wide hole foot but you have straight stitch foot on. could also mean timing between needle and shuttle is out of sync.
or needle size is too small for weight of fabric you are sewing.
check out www.sewing.about.com for needle size info and use new needle for each new project.
if yoy suspect timing out take to technician for fulk service.

This machine, when you have it on straight stitch, will sew with the needle to the left. If it's hitting the pressure foot, you may have the wrong pressure foot on the machine. If it's hitting the needle plate when you have the pressure foot removed, it's possible you have set for zig zag and you have a straight stitch needle plate on the machine. I believe this machine came with 2 needle plates. One for straight stitch, and another for zig zag.
