Your videos are well produced with great instructional content. Great audio levels, camera angles and lighting. What else can I say - thumbs up.
I appreciated your info on the1508, please add more.
I can probably do something else on it. Did you have some specific points of interest?
Yes. Thank you. Would you address the heavy-duty version? Is there much of a difference?
@@AlexanderDyer Really helpful video, thank you! Can you also discuss more about how to adjust tensioners when moving between lighter weight fabric such as canvas or interfaced cotton and vinyl/cork/canvas? I can’t find any info on this so far. I hope my question makes sense. Thank you!
Well, that cleared something up for me! I knew I could increase tension by increasing the wraps at the multi-hole guide, but I didn't really know WHY I might do that - to increase tension without putting all of the tension in one spot. Thanks for the informative video!
I am glad to hear this. I have been considering a back pack project and I will definitely be re-watching some of your videos for pointers.
Bravo Mr. A. Dyer. I appreciate your video of threading your Juki 1508. Your know-how has solved my problem of frayed thread on my 241H... you've saved me anxiety, time, etc. I appreciate your generosity.
Thank you so much. I've had to come back and review this several times and so appreciate it every time.
You just solved a year of headaches.....but ours is a 1508NH! GREAT explanation. Thanks so much.
James, I have the NH as well. I would appreciate keeping in touch. I am still learning its features and troubleshooting.
Really helpful - thanks.
Thank you for the support Harry, I'm so glad you are a viewer of my channel as I am of yours. :)
Thank you again and again. I keep coming back to remind myself how to do this. Eventually I'll get it!!😘
I installed that tension assembly on my 1541. It worked perfectly. I noticed the default one had to be tightened up so much more than I cared for on heavier threads.
The right tools make things better.
I just bought a used juki lu1508nh. Would love more videos on troubleshooting
Congrats on your new machine, I love the 1508. Sewing machine basics carry across all sewing machines . You may find this video to be helpful in operating your 1508 th-cam.com/video/dVprkJXNma0/w-d-xo.htmlsi=JzCYStszc8NQ6ity
I own a Juki LU 1508 and I would like to see placing the bobbin, bringing the bobbin thread up, and oiling procedures. Thank you for your time.
alexanderdyer.work/wp-content/uploads/2020/03/LU1508NH-Instruction-Manual.pdf
@@AlexanderDyer thank you for taking a moment of your time to help me out. Keep up the excellent work.
Well done. I have two singer 1591's, hoping to sell one at some point and upgrade to a commercial walking foot. Your videos are always food for thought.
Think of it as an investment. They hold their value very well for resale and they can even make you some money. Thanks.
You answered a question I always wondered. Why would you need multiple tension stages? Now I know.
Thank you for the lesson it is much appreciated for a beginner like myself.
:)
I love this kind of video. The 1508 is similar to my 1541 except the tension system. I also use that same needle threader.
Now that you show that the thread must click into the metal disk part after the double tensioner, mine does no seem to do that, and that may be why I get so much inconsistent stitching. I'm constantly fiddling with the bobbin tension, when I should be troubleshooting that metal disk setup. Sorry, I dont know what it is called.
Thanks for the educational videos. I always use them for reference and tell others to look you up when they have service questions.
Great! And Thanks for the references.
That is a take up spring assembly. It keeps just a touch of tension on the thread as the needle descends and pierces the fabric. This tension keeps any slack thread from getting accidentally caught by the point of the needle.
Awesome thank you for posting this.
Just got one and this was abig help
Good video. It seems like a good advancement for all machines would be to use those small off the shelf spools of thread instead of bobbins. There is no reason those small spools couldn't be used instead of those tiny bobbins.
Actually there is a reason and that has to do with how a sewing machine makes a stitch often a couple thousand times a minute or more. You see the thread has to be pulled all the way down through the material and completely around that bobbin. So that is why they tend to make the hook and bobbin smaller. Actually the bobbins on this machine are quite and relatively large. To get a larger bobbin you would have to go to say a 441 clone like the Cobra or Cowboy leather stitchers.
Interesting video. Thanks.
Work mostly on leather cow/horse so undecided between 1508H and 1541. Currently have a Juki 563.
I think they are both fantastic, the 1508 being slightly more capable according to specs but it is not much. I have used them both and they are very similar. Check out the specs on Juki's website. The 1541 is bound to be cheaper and more available. Have fun.
The silver one makes a harsh clicking noise as I sew it's factory drop in.. haven't messed with because I tried to loosen it a little and tweeked the wire so had to order a new thread tensioner replacement. There is a metal thing with micro screw under the plate. By the wire that snaps the thread into place..wondering what's that for. So any help you can give would be awesome thanks. But I didn't know about that so good video
Very thoughtful and well done video!
We have a 1508 and a 1508n. There is a difference with tensioner plates and amount of tensioners. Can you provide a “how to thread a 1508” too please? Also how to oil each model and how often in a manufacturing factory environment.
Maybe this tensioner looks like yours, tensioners are multiple and exchangable. th-cam.com/video/aaNsmgHQzTo/w-d-xo.htmlsi=CPvHh0pKoLMtbVIK Here is the manual to refer to for lubrication. alexanderdyer.work/uploads/manuals/Juki%201508%20Engineer.pdf
Great vid...Thanks helped me loads....Nige UK
Thanks...Your Welcome...I'm glad it helped.
Thank you for this video
My top thread keeps shreading. Using size 22 needle with size with Tex 90 thread. I never new you could only use one tension and not have to use both! Do you know why my thread is shredding and breaking after each time I sew? Thank you
Is your thread new and of good quality? Poor thread can do that. A burr on the hook can cause this too. Watch your thread as it passes around the bobbin, slowly by hand.
Would you know what's the main difference btw juki 1508 and the 1541s? I found a barely use 1541s complete for $800 and plan on doing some leather work, but I want to know the main difference thanks
5 year old video what what do you suggest for size #69 thread? Use only one tensioner or do I use both tensioners for size #69 nylon thread?
The information remains valid and will apply to the tex 69.
Hi there I got the same machine but I have few questions that I would like to see if you can help me out. Where do I put the oil in? Is the machine cut the thread itself?

This is helpful. My 1508 didn't come with a manual. I'm having trouble with bobbin stitches looking like they are pulled. I need to fix it and don't know how.
Check out my video of thread tension.
@AlexanderDyer I did, thank you, it helped!
Great! I'm glad it helped.
Hello, I was wondering if is there any adjustment nob/bolt for speed on this sewing machine , I used to have a old sewing machine Consew and it was way faster than this one LU-1508N, please let me know.
Machine speed is an effect of the motor and the pulleys that transfer the motor speed to the machine. Watch this for more info of motors. th-cam.com/video/lavkvsU5ltk/w-d-xo.html
@@AlexanderDyer thank you very much!
we would like to know if the 1508 duki is good for sewing heavy duty upholestry leather could you show a viedo.
It is ideal. Thanks for the idea.
I’m having issues getting the balance of thread stitch. When using lighter fabrics and let’s say a 69 thread should I still omit the second tensioner?
th-cam.com/video/xax0RTCqYTk/w-d-xo.html
@@AlexanderDyer thanks. Yea I’ve seen that video but am still having issues. I think it could be a difference in thread weight from top stitch and bottom stitch. Plus I skipped one of the tensioners on my 1508nh
Nice 👍🙂🙂
I'm interested in learning how I can make the majority of fixes myself on my juki.
Does anyone here know why you would need more tension on thicker threads? It would seem to me there's more resistence on a heavier thread to pull through all the tension points, than it would be to pull a thinner/lighter thread through...
Thanks, l wonder if you could do a detailed video on how the bobbing is threaded under the Juki 1508n
Thank you for a great video. My question is on thread thickness and what is considered “thicker” thread where you would use both knob tensioners? I am using coats continuous filament nylon M 40, T-70 with size 20 needle. Should I be using both of the knob tensioners or just one? Thank you
Hello Alexander, it's me again bothering you....sorry mate. at 01:14 of this video i see a very nice guide arm nearby the machine foot which it seems to be adjustable, ok my question: is this guide an option for most machines or only a very few can have it or have it by default? - i appreciate your support
thanks again my friend.
I show it here and links are in the description. th-cam.com/video/QMYmohWrHE8/w-d-xo.html
@@AlexanderDyer thanks Alex, already in my basket with your link
What about the larger tension with the hook at the bottom?
I cover that in this video. Thank you for watching. th-cam.com/video/xax0RTCqYTk/w-d-xo.htmlsi=--doJI9RqDfLuTG2
Thanks. I’d like to learn how to change needles and threads of different sizes and any setting changes needed.
Gotcha. Have you seen this video? It might hold you over. th-cam.com/video/EJlrjWJKdTE/w-d-xo.html
I have a 1508 n and when sewing get skip stitches can you explain how to rectify that. thank you bob
Depends on when it does it. Try a fresh needle, let the machine feed itself, turn your work at the right phase and most skips will be avoided. Don't know what phase I am talking about? I cover it in this video. th-cam.com/video/D3QuCF6zATg/w-d-xo.html
I bought new lu-1508. I have problem change the bubbles.
Can u show how to change bubbles.
Love your videos! I'm learning alot of sewing in general. I just bought a used 1541s and was wondering what size thread do you skip the second tension and what thread do you use both tensions? Also do you use a speed reducer reduction pulley on your machine? Thanks for your time.
I don't know but a guess would be somewhere around Tex 69. Try the way you prefer and see if you get good results, if you do then it is right. Ha ha. I have a speed reducer on a 1508 but not on the 1541 so I have experience with both ways. The speed reducer is nice for small or intricate work where every stitch counts. Sewing on the one without the speed reducer is really good for upholstery type sewing. Both have servo motors. First I would recommend a Servo motor, you can always add the speed reducer later if you want.
Ok did you install your speed reducer yourself? Can you explain in detail of you method? My speed reducer will be here in a few days and want to install it right. Thanks
I have a 1508n and I keep running into the same problem which is my thread keeps breaking so I reduced my tension but it keeps doing it.
I don't know what your particular problem is but if your thread is rotten from say sun damage it will break. Try some different / good thread, change your needle and make sure your machine is threaded correctly. These things will solve most problems.
Just bought a new 1508 and its been in the repair shop longer than its been in my shop. Jammed within seconds when I sewed on it the first time and after 3 trips to the repairs shop, it keeps on jamming. Now the hook looks like it shouldn't look. Anyone need a boat anchor???
I love to buy boat anchors. What part of the country you located?
@@AlexanderDyer Central California, Modesto area. Just got this junker back from the shop (trip #4 for the same problem) and it jammed-again- within 100 stitches. I doubt its good for parts so I'm going to toss it and take the loss. No more Jukis....
Hi! is it easy to install or add speed reducer on my new machine? is something that I could do myself?
Sorry, I can't really answer that question. I think that some people will be able to and others won't. It depends on one's mechanical aptitude for one. It is certainly a very straight forward project and if you have the desire to tackle it then you probably have you answer there. Good Luck.
How do you adjust tension on bobbin?
Watch my video on bobbins! 😎 th-cam.com/video/NYE5B6OPj4k/w-d-xo.htmlsi=ROsQxl0XmeHEDsph
When would a guy choose this machine over say a 206RB? I'm assuming with the double tensioner it can handle larger threads, but is that the only significant difference?
I think the first consideration would be does the guy have this kind of money. These will typically cost more but it is a classic case of you get what you pay for. These machines are very well made in Japan by a very well respected company. Top loading Big Bobbins, integrated bobbin winder, and a much improved feeding motion which handles the thicker end of materials better by entering and leaving in more vertical motion that most machines. Check out Juki's website for specifics. Is it worth the extra money? Each guy must decide for himself based on his individual situation. Have fun.
Thank you so much for this video! Very helpful. I am having trouble with my top thread shredding.. any advice?
For me this is usually solved with fresh high quality thread.
I like that skinny presser foot. May I ask for details on where I can find one?
nickosew.com
Great explanation of how the tension disks affect the thread. If you have advice as to how to avoid thread bunching/breaking on this machine I would love to see it. I can't get my NEW machine to sew over two layers of leather without the thread breaking. I know this should be no problem, since I did it regularly with my LU 563 and this machine worked fine at the shop when I bought it. Thank you! #69 thread / 22 needle / 1/8" pliable leather
Bunching? If the thread is making a rats nest on the bottom of the material then your tension should be tightened. It is probably a simple adjustment so take heart, you will get it.
Thanks for the helpful video. Question for ya - do you have a preferred source to get accessories for that 1508n? I saw you have a rolling edge guide. Thanks!
amzn.to/2MjnJMF Enjoy!
I just purchased my first industrial juki lu 1508H! is it necessary to add speed reducer on it or servo will motor will handle slow speed when I need to? your responses are much appreciated!
I have one machine with servo motor and speed reducer, it is really nice and slow. Most everything else i have are just servo motors and they are great and slow enough but it just depends on how slow you want to go.
Is it easy to install speed reducer?
Do you have a video for adding speed reducer on your Servo motor? Love your videos you are very clear and partcular on explaining❤️
any ideas why a machine like this keeps getting loose?
What is loose?
@@AlexanderDyer the tension
@@AlexanderDyer it can be tightened over and over and then goes back to being really loose again. it also sometimes shreds the thread. like it’s way too tight.
I'm reading that your tension fluctuates from loose to tight. Let me know if this helps. th-cam.com/video/dVprkJXNma0/w-d-xo.html
Great video! I was the guy that asked you about thread tension on the 1508 in one of your other videos. I've had good success getting the thread tension right via the top thread, but I still wonder how to set the bottom correctly as an initial setup.
I guess it's a case of just reading the sewing, too loose all over, gathering, top to loose and I get a 'line' on the bottom stitch or top to tight and I get a 'line' on the top stitch right?
Yes I remember, your question was the seed for this video. Thanks.
Set your bottom tension where it feels right when you pull it by hand. Once your bottom is set, leave it alone and do all adjustments on the top. This will work for 99 percent of your projects. Probably.
Sorry Shueysstuff, I accidentally deleted your last comment.
To answer your question, Yes, I would like to do a 1508 timing video, I am not sure just when I will get to it though. Stay tuned!
Alexander Dyer fantastic!! I look forward to seeing the video when timing permits... err time permits...
Hey Alexander. I'm still keen to see a video on how to set up the timing on a 1508, so keep it in mind if and when the opportunity for you comes up. Thanks mate!
Great video and great bag! Have seen this video a lot of times and each time I watch it I learn something new. What serger machine do you use for the canvas? I have been advised by a friend that YAMATO would be a good brand to go for. Any ideas on this particular brand?
This is the overlock machine that I used on canvas th-cam.com/video/6bOUShDvsX0/w-d-xo.html Merrow makes a real good machine and they are still in business in the USA so the parts will be there.
Good video. What are your thoughts on the Juki DDL5550 as a first or entry level industrial machine? Would you recommend others?
It always depends on what you are going to sew. If garments then yes it is very good, otherwise watch this video. th-cam.com/video/lbhWnIwu8rk/w-d-xo.html
Thanks for the link. That's a nice machine. Now I'm on the hunt for one.
Hi. Love your videos. Thank you for making them. Looks like your machine missing a thread guide after check spring,
If your machine had that thread guide you would tread the machine the same way that you did it in this video or you would do it different way?
I do have a Juki LU- 1508
alexanderdyer.work/wp-content/uploads/2020/03/LU1508NH-Instruction-Manual.pdf
@@AlexanderDyer Thank you so much .
Mr. D, I have a brand new 1508 which i bought as an (so I thought) upgrade to my 1541. I have an issue with birds nesting on the bottom when I sew in reverse even just for a backtack. Forward it's fine. Any ideas? Thanks!! BTW, you have the best instructional videos on you tube. Love the canvas bag videos.
Maybe the thread is catching somewhere, maybe on the opener? run it by hand with the hook exposed to see if you can spot the problem.
Sweet sewing machine is it your favorite?
The answer for me is not an easy one, that is to say it is not as simple as yes or no. I have maybe a dozen machines and they are "mine" because I love them. I have had many dozens of machines but most of those have been moved on to others that will love them. I also have the similar Juki 1541 and I like them both very much but for sewing garments and what not I have a needle feed Brother that can't be beat; but that is off the point isn't it?
If you are trying to decide what walking foot to get and you are considering this one then I highly recommend it. It is a great machine that is very capable and a joy to operate.
I hope that somewhat answers your question.
Thanks
It helps. I bought my first sewing machine after watching one of your videos, a Singer 201 in beautiful shape and I love it. I am looking for a walking foot machine now. I think it's a harder choice because of the many very good machines to choose from both new and used. Thanks for all the videos you make the information is very helpful.
Great video!!! super instructive. I wonder if I could request that you do a video for how to oil this specific machine.
Thanks
Thanks Carlos Sanches, I'll see what I can do. I appreciate the input.
I am really happy that you took the time to reply. That is great!!! Thank you for considering the request. I am new to JUKI and as a young entrepreneur just starting a sewing business I would really like to protect my machine by taking good care of it. After all it is my bread winner :).
Thank you,, one question,, my Lu-1508N KEEPS GATHERING..!! PLEASE HELP..! Thank you
Most likely your thread tension is too high causing the stitch to draw up and pucker each stitch. Here are a couple of videos I have made that might help you smooth it out. Good Luck.

Hi Mr Alexander ☺ THANK YOU..!! on evey other machines I've switched on, I Can easily pull on both top and bottom threads at the same time and feel if the tension is about equal..!! Unfortunately with our new Juki with double tensioners,, it's a lot more complex..!! Thanks Again..!! I'm using #69 THREADS..! is #69 threads your first choice that you use on your Juki 1508 please 🙏
