Sewing machine repair: Hook timing

Hook timing is a fairly common problem that sends many sewers running to the repair shop. When it happened the first time on my older Kenmore, I decided to try to repair it myself first. My thinking was, since it’s a mechanical machine with mostly metal parts, as long as I was careful, I couldn’t really hurt anything. I probably would have thought twice before attempting it on a computerized machine.

All machines are a little different, so what worked on mine may not work on yours. Something I recommend to everyone who wants to work on their own sewing machine, is getting a copy of the service manual. Honestly, I still need to do this. There’s tons of info online, but having the actual service manual is even better. You should have an owner’s manual on hand, too. It  covers basic care and maintenance. For repairs, though, the service manual will give you technical instructions and confidence. 

Hook Timing?

Before taking things apart, determine if hook timing is causing the problem. If the needle (top) thread isn’t picking up the bobbin (bottom) thread, hook timing is a prime suspect. It’s always a good idea to rule out simple problems first, though. Try swapping the needle, rethread the machine and sew on some scrap fabric. If it’s been a while since you’ve dusted the lint out of the bobbin case or you’ve been sewing on linty material, give it a good cleaning.

Once you’ve tried the easy fixes, if it still isn’t working right, look at how the needle and the bobbin hook intersect. This page, https://tv-sewingcenter.com/general/sewing-machine-timing-hook-timing, has illustrations, photos and descriptions for where they should meet on both rotary and oscillating machines. 

Taking a look at my oscillating hook.

My machine is an oscillating machine, so the hook tip should pass just above the eye of the needle. Mine was passing below the needle’s eye, so clearly the hook timing needed adjustment.

Open it up

The first and honestly the hardest step was figuring out where all the screws were that I needed to remove to take off the casing. (Actually, the first step was to turn off and unplug the machine. If you’re attempting this at home, do not skip this step!) On my Kenmore, I have to take off the side by the hand wheel, a plate on the bottom, and the front panel. 

More cleaning

While I have my machine open, I like to take the opportunity to clean it out and oil it. Oiling a linty machine, using the wrong oil or putting it in the wrong places can cause tons of problems, though, so if you’re not sure, stick to dusting only.

Find and adjust

Next, I tilted the machine on to it’s back so I could get a good look at the mechanism that rotates the hook. Once I had isolated that, I found a hex head set screw. Loosening that allowed me to gently adjust the hook position so that the tip passed just above the needle’s eye.

About in the middle, just above the motor is a silver piece with a round, black screw near the top. That is the set screw I loosened to adjust the hook timing.

When I was sure I had it properly positioned, I tightened the set screw. I turned the hand wheel a few more times, making sure everything still looked good before I put the casing back. A quick test run showed everything was working properly again.

Done!

It’s so satisfying to be able to make simple repairs to my machines myself, especially when most repair shops start around $75 and go up from there, depending on what needs to be done.

Easy fix for worn out denim jeans

I have a pair of denim blue jeans that are still in good shape except for where my thighs touch. There they are really worn on one side and there is a hole on the other. Because of where the hole was located, I wasn’t comfortable even wearing them around the house, so I decided to try a simple fix.

First, I ironed lightweight fusible interfacing on the inside of the worn areas, making sure to completely cover all the worn out spots with the interfacing.

Once it was fused and cooled down, I turned them right side out. Using a narrow zig-zag, I stitched back and forth over the hole and worn areas. This serves to secure the interfacing and add strength.

If you can, drop or cover the feed dogs on your sewing machine in order to be able to move the jeans freely under the needle. The machine I used doesn’t have a way to drop them and I don’t have the special foot plate to cover them. Instead, I used a combination of repositioning and forward and reverse stitching to make it work.

Depending on the location, you could use contrasting thread and decorative stitches to turn the repair into an embellishment.

I also have a pair of jeans I love, but they needed a button sewn back on. They were also always a little short, so I replaced the button and let out the hem while watching TV one evening. These are heavier denim, so it will be another month or two before I can wear them much, but at least they are ready.

Buttons!

These have an obvious line where the hem used to be, but they’re cute so I don’t care.

A Tale of Two Suburbans

Our family of five people, two dogs, one cat and a chicken is in need of something larger than our car. Sure, it’s fine for everyday driving, but for long trips or anytime even one of our pets needs to come along, things get a bit…snug.

This guy takes up a lot of room.

So, we bought this at an auction:

The Zombie truck.

It’s a little rough, but it runs and can haul people, pets and supplies from Home Depot. It’s missing the third row seat and needs a few other parts to be perfect. Instead of buying them piece by piece, we found a parts donor for it for less than the parts would be individually. The problem with that is, minus needing a paint job, the donor is in excellent shape. The interior is spotless, and the transmission was recently rebuilt. It just won’t start.

Beckett approves of Suburban number two.

Because Suburban number two was obviously well cared for, we’re attempting to diagnose the problem and repair it. That would allow us to retire my car completely. Which is good, because, as of yesterday it’s broken down in my driveway. Luckily it’s not too difficult of a problem to fix this time. It’s more expensive to maintain, though, and I’m not so sure a major repair isn’t in it’s near future.

Replacing ground wires on Suburban number two.

Our first attempt at troubleshooting involved replacing the ground wires. We had high hopes, since a faulty ground left us stranded in a previous Chevy truck, and it’s one of those easy to overlook problems. Alas, either that’s not it or my mechanic skills aren’t up to par. Luckily we have a few more relatively simple fixes to try before we get to the hard stuff.

Sewing Machines

I’m a bit of a sewing machine hoarder. If you don’t count the one that is Finn’s, I have four. That includes my sewing and embroidery machine combo, but not my two sergers. Also not including the knitting machine, because it knits.

While I’m certainly not an expert, I do have my preferences. I would take a well-built, old metal machine over a new machine any day. Mainly because when they break, I tend to do this:

That is my first sewing machine. It is a Montgomery Ward’s Signature sewing machine from the 60s, I think. I got it from my mom who got it from my grandma. I can’t remember what was wrong with it that time, but it sews nicely now.

The Signatures at that time were made by a Japanese company that specialized in industrial machines, I think for sewing feed sacks. That translates to a heavy duty, domestic sewing machine that will sew through anything. It also has a set of cams. Cams are interchangeable disks that allow it to sew pretty embroidery stitches.

My next sewing machine is another, slightly older Montgomery Ward’s Signature. This one was rescued from a lot of machines that were destined for the junk heap.

I love the blue color! It reminds me of cars from that era.

Like the other Signature, it uses cams. You can see them in the little accessory box. I actually like this one a little better than the other. It sews the prettiest straight stitch out of all my machines and has a cam that stitches a row of teeny tiny hearts!

I’ve never actually made anything on it, though. Unlike the other, this one is in a portable case, which is hilarious. I carry/wrestle a 31 lb. two year old every day and lifting that machine is a struggle. Since I don’t have a dedicated place for it, I don’t have the motivation to lug it out.

My workhorse is a 90s model Kenmore, made by Janome. The case is plastic, but all the internal workings are metal. I know, because I had to open it up when my walking foot vibrated the needle loose and messed up the timing. Photographic evidence on Instagram.

That is the best photo I could find of it. I love that machine because it isn’t as quirky as the Signatures. It also tells me how to thread it right on the machine, and when it comes to sewing machines, threading is half the battle.

My final machine is the Brother SE400 embroidery combo. I keep it set up as an embroidery machine because I have three other sewing machines. Also, it scares me, so I want to risk messing it up as little as possible. I haven’t had it opened up beyond the bobbin area, but I’m guessing there’s some plastic, and I know there is scary electronic components. With the other machines, I am freer to play because I know that if something happens, it’s not likely to be catastrophic. With this, something like a timing issue would definitely mean a big repair bill.

But, it makes pretty embroidery, has loads of decorative and utility stitches as a sewing machine, and has the most awesome needle threader I have ever seen. Seriously. Finn’s machine has a needle threader that I will never use, because it is complicated and I stabbed myself with it one time. Brother’s needle threader is like magic. It is especially handy when embroidering with multiple colors. Color changes take mere seconds.

Just to show I’m not as much of a hoarder as I could be, here is a photo of the White machine I couldn’t get working and sold on craigslist.

Then, while I was waiting for the buyers to show up, I decided to play with it a bit and figured out what was wrong. I hope they love it, or at least open it up to look at from time to time. Sigh.
