  • 00:00

    It’s been another fantastic sewing marathon for me but my machine has certainly seen some

  • 00:04

    fiber.

  • 00:05

    It’s time to get it all cleaned out.

  • 00:06

    And I thought what a great way to present to all of you good troubleshooting knowledge

  • 00:11

    and maintenance knowledge on drop in bobbin machines.

  • 00:13

    Let’s get started.

  • 00:19

    So as you can see nice and close here I’ve got a bit of mess inside of my machine.

  • 00:24

    Now of course you know I’m goofing off a little bit.

  • 00:27

    But I have literally taken my machine apart before and especially sergers and seen this

  • 00:31

    kind of mess.

  • 00:32

    There’s a few major things that will happen especially with drop in bobbin machines.

  • 00:36

    And the first one is too much fuzz down in your stitch plate area, your feed dog area,

  • 00:42

    your bobbin area.

  • 00:44

    So one of the things I do is I always remove my stitch plate.

  • 00:48

    And I’m going to caution you right now you should always do this with the power off on

  • 00:51

    your sewing machine.

  • 00:52

    But today I’ve got the power on on my machine because I’m using the lighting so you can

  • 00:56

    see better a little bit.

  • 00:57

    So power off on the machine and of course you will have your needle out of your sewing

  • 01:02

    machine.

  • 01:03

    But I need the needle to point out some of the things for timing issues so I’m doing

  • 01:06

    a few things a little different than I want you to do.

  • 01:09

    So here we are down in the drop in bobbin area.

  • 01:12

    And the first thing I do is I don’t use a can of spray air to clean this out.

  • 01:16

    I use my hands and I remove as much of the fuzz from the bobbin area as possible.

  • 01:22

    I get all of that out of the way first.

  • 01:25

    Then what I want to do is I want to take my bobbin itself out.

  • 01:28

    And if you’ve never done this your instruction manual will show you not only how to remove

  • 01:33

    the stitch plate and any extra cover plates but it will also talk about this drop in bobbin

  • 01:38

    itself.

  • 01:39

    So this black drop in bobbin piece, we’re going to maintenance and talk about putting

  • 01:42

    it back in in a few minutes.

  • 01:44

    The first thing I do is I remove it and I just take my brush and start cleaning off

  • 01:48

    all of the little areas.

  • 01:51

    Now with a drop in bobbin, a lot of times there’s going to be a piece of velcro fuzz

  • 01:55

    or wool or something along that area.

  • 01:58

    That helps our threads glide.

  • 02:00

    So not all of this is fuzz that needs to be removed.

  • 02:03

    So don’t chip away at that with an old butter knife or something.

  • 02:06

    I also clean this all the way out and at this moment let’s talk about a couple of troubleshooting

  • 02:13

    things.

  • 02:14

    So I’m going to do maintenance and troubleshooting hand in hand today.

  • 02:17

    One of the things that happens often is you get a thread jam with a drop in bobbin machine.

  • 02:21

    The drop in bobbin itself can keep spinning as the machine is jamming up.

  • 02:27

    And you’ll actually take your needle and you’ll pierce with the needle.

  • 02:31

    Pierce, pierce, pierce with your sewing needle through there.

  • 02:35

    That will start to cause some erratic looking stitches in your straight stitch.

  • 02:40

    You’ll see an occasional weird, funky stitch on the back and things.

  • 02:43

    A lot of times that’s because that little barb that was formed as the needle pierced

  • 02:47

    through that bobbin case is catching on the threads.

  • 02:50

    The other thing is is this bottom lip rides inside on the back of what we call the track

  • 02:57

    or the race, the bobbin area.

  • 02:59

    And if there are piercings through there it can float and wobble and make a bunch more

  • 03:04

    noise and just become less accurate.

  • 03:06

    So if you’ve struck your bobbin case with a needle you can take your thumbnail a lot

  • 03:10

    of times and like push that plastic back into place.

  • 03:14

    And if it works you’ve fixed it.

  • 03:16

    And if not we need to get you out there and we need to replace that bobbin case.

  • 03:20

    So that’s one of the troubleshooting things that happens with drop in bobbins often.

  • 03:24

    Now that I’ve got that bobbin case out of the way I’m going to come in here with a

  • 03:28

    brush and I’m going to continue to brush away the fiber and the lint out of here.

  • 03:33

    Now the stuff that you’re seeing now is real fuzz.

  • 03:36

    This is not prop fuzz from the props department.

  • 03:39

    This is the real stuff coming out.

  • 03:41

    And the place that we get a lot of fuzz that builds up is in our feed dogs, right in here.

  • 03:46

    Now whether that’s drop in bobbin or regular bobbin machines cleaning out your feed dogs

  • 03:51

    makes a great help especially if your stitch length is not real regular.

  • 03:57

    It means your feed is not going real well.

  • 03:59

    . So I’m going to go at here and I’m actually going aways.

  • 04:02

    I dust before I do any oiling.

  • 04:05

    And I’m dusting through here and I’m dusting through here.

  • 04:07

    And I want to point out a couple more things, ok?

  • 04:11

    So come in real close here and first of all this metal ring is a magnet as a matter of

  • 04:17

    fact.

  • 04:18

    And that magnet will help you with the metal portion of that drop in bobbin case.

  • 04:24

    It helps it sit in here properly, which I will tell you how to set it in here properly

  • 04:29

    in a second because I’m not doing it right.

  • 04:31

    Oops.

  • 04:32

    What I’m trying to point out is how that metal holds it in there securely.

  • 04:37

    So if you get too much fuzz between that magnet, and that’s the first place to look if the

  • 04:40

    fuzz builds up, you’re going to cause that magnet to break its contact.

  • 04:44

    And it’s not going to be able to hang onto that metal base of the bobbin case.

  • 04:49

    And that helps it not float around.

  • 04:50

    This magnet, in a lot of machines, it will just pop out as well.

  • 04:53

    So be careful while you’re dusting in here that you don’t knock your magnet out of

  • 04:57

    place.

  • 04:58

    This machine does not have a wick right here, although a lot of drop in bobbin machines

  • 05:03

    I meet will have a wick right in here.

  • 05:05

    You will see a square cutaway and it looks like fuzz or lint.

  • 05:09

    But it’s not, it’s a little wick that you would put a couple of little drops of

  • 05:12

    oil on there about every 30 days.

  • 05:14

    Ok, I see one more little piece of fuzz I want to get out of here before I start talking

  • 05:20

    about putting it all back together.

  • 05:21

    Now there’s a lot of other parts in here you could talk about maintenance but you could

  • 05:25

    talk about the drop in bobbin today.

  • 05:27

    Oops.

  • 05:28

    I just want that one little last piece of fuzz.

  • 05:32

    Now at this point if you had a can of spray air you could hit it with one or two little

  • 05:36

    blasts because the cover is open and a lot of that fuzz is out of there.

  • 05:40

    I still don’t love it.

  • 05:41

    At home I use a real air compressor because it doesn’t have moisture in it and that’s

  • 05:45

    why I come through here in an air compressor and blast all of the rest of the little fibers

  • 05:49

    out of the way.

  • 05:51

    Now I will often use a drop of oil.

  • 05:54

    And I’ll either put it right here.

  • 05:57

    This is the race or this is the lip that the black bobbin case is going to sit on.

  • 06:03

    So you can either put a drop of oil right there if that’s easy for you.

  • 06:07

    But the other thing you can always do is you can just flip your bobbin case over and you

  • 06:11

    can put a drop of oil right here on the underside out on that edge.

  • 06:17

    And then as this seats back into the machine that drop of oil is going to be there.

  • 06:22

    Some manufacturers do not want you to oil your machine.

  • 06:25

    This is something I do often and these bobbin cases, yes they are plastic but they’re

  • 06:29

    also fairly inexpensive.

  • 06:30

    And I think that’s where the debate lies is whether the oil will wear it out.

  • 06:34

    I haven’t seen it be problematic yet.

  • 06:36

    Ok now this is really important.

  • 06:38

    As we come in here this opening, the upper edge of the bobbin case is going to line up

  • 06:42

    square to these feed dogs.

  • 06:45

    So I’m going to come in here and try to slip it in and I’m going to point out the

  • 06:48

    other two things I’m looking for.

  • 06:50

    Ok that went in nice and smooth.

  • 06:52

    That’s just how I wanted it to fit like that.

  • 06:54

    Now you can see along this edge, it is now seated perfectly within the race.

  • 06:58

    And then most drop in bobbin machines will have one piece right here that is called the

  • 07:04

    position finger.

  • 07:05

    It’s a little spring that allows for our thread to come through here.

  • 07:07

    So you want to make sure that spring is still activatable.

  • 07:10

    So that would be another troubleshooting thing.

  • 07:12

    If your threads are getting stuck as they come through make sure there’s not something

  • 07:14

    caught on here.

  • 07:16

    As well as make sure this nub is on something.

  • 07:20

    A lot of times they will get stuck over here.

  • 07:22

    This machine has a white mark to match up those two areas.

  • 07:28

    And then a lot of times on the back side of the bobbin of the covers there will another

  • 07:34

    tab that will actually help hold in all of the working parts.

  • 07:39

    So all of this may not be completely secure until we have the rest of our stitch plate

  • 07:44

    down, ok?

  • 07:46

    So I just want to make sure that’s lined up.

  • 07:48

    It’s nice and square.

  • 07:49

    And we want to make sure we do not pierce through that with a needle.

  • 07:52

    I would always put in a fresh needle when I’m doing maintenance.

  • 07:54

    Of course you know I love my micro techs sharps needles.

  • 07:57

    They work fantastically, right?

  • 07:59

    And then there’s one last thing I want to point out, really important when it comes

  • 08:03

    to the screws within the needle plate itself.

  • 08:07

    These screws are not real easily found at the hardware store.

  • 08:10

    And a lot of times the screws are either going to have on this head, it’s going to have

  • 08:14

    this bevel, like this triangle angle to it.

  • 08:17

    Or this one has an additional little lip.

  • 08:21

    So when you start to put your stitch plates back on the machine what you’re going to

  • 08:24

    do is you’re going to slightly drop these into place.

  • 08:28

    And you’re just going to finger tighten them first.

  • 08:30

    The way the head of the screws is set up it helps bring that stitch plate right in so

  • 08:34

    that it winds up with your feed dogs.

  • 08:36

    Now as I bring it over to the machine to show you that I’m going to turn the lights off

  • 08:41

    on the machine because this machine has got a safety feature on it that’s going to start

  • 08:44

    beeping and making all kinds of noise.

  • 08:45

    Ok, so I’m just going to kill the lights but now you’ve been able to see the bobbin

  • 08:49

    case.

  • 08:50

    Now as I bring this around, ok what I’m trying to say is I want to make sure this

  • 08:57

    lines up with the feed dogs.

  • 08:59

    And then I bring these screws in.

  • 09:03

    And I finger tighten them to make sure they go in correctly.

  • 09:07

    If it takes any force that means that your threads are not lining up correctly.

  • 09:13

    And if you’re looking around in your tool kit that came with your machine you might

  • 09:18

    be looking for something that looks like this as a screwdriver but funny enough a lot of

  • 09:21

    the new machines have this little wonderful tool like here.

  • 09:24

    It’s a little bit larger than a quarter and that part down there is a screwdriver.

  • 09:29

    So you can use that to come in here like yay and tighten that up.

  • 09:39

    And now that that’s on I can turn the light back on on my machine because I put the screw

  • 09:43

    in to keep the beep from happening, right?

  • 09:45

    And I want to point out lastly is these screws are still sitting in here pretty nice and

  • 09:49

    loose and I put them both down at the same time to make sure that the feed dogs are in

  • 09:54

    line with the stitch plate.

  • 09:57

    And I wish I had two little fingers that fit in here but I don’t.

  • 10:04

    Sometimes you can come out here with a little larger screwdriver.

  • 10:06

    Oop, I’m going to use this one.

  • 10:11

    It always seems so much easier when you’re all not watching me.

  • 10:15

    That’s alright, I love the fact that you’re watching me out there because if you weren’t

  • 10:21

    watching me I wouldn’t get to do this kind of stuff.

  • 10:24

    There we go, ok.

  • 10:25

    So now that one is secure.

  • 10:26

    I’m going to come back over here and I’m going to re-secure that one.

  • 10:30

    Everything is fantastic.

  • 10:31

    And then the last thing I would go ahead and do is lock in the rest of my stitch plate.

  • 10:36

    Like I said, I’m going to put in a fresh needle.

  • 10:38

    And this machine should be ready to rock and roll for another good 30 to 60 days worth

  • 10:43

    of sewing.

  • 10:45

    Except for that needle.

  • 10:46

    A fresh needle at the beginning of every project will make your sewing as awesome as it always

  • 10:50

    is, right here at Man Sewing.
