Can you help me understand the difference between the juki dnu1541s and the juki du1508ns?

then I practised with my eyes closed ( no distractions ) ..after 15 minutes , no problems..no dropped bobbins..now

Believe me I have tried. Not that the hands are that big per say but thick fingers. A couple of years ago I had a Singer featherweight too see what all the fuss was about the featherweights. Nasty little machine. To get the bobbin in it was easier to flip it over with the front folded up and with a old VS machine had to use large twisters to get the long bobbin in.

but the new kind of soles either spilt across the foot or collapse inside.

I think their isn't enough rubber for flexibility in the soles anymore like there use to be. If you have a good pair of work boots and can find someone to make soles from an old car tire they will outlast the uppers. Finding someone able and willing to cut soles with the heavy iron to sew them on maybe a problem.

Another nice feature of both these (light version) machines are their 441 compatible needle systems.

There is a conflict in that statement. The 441 machines (e.g., Juki TSC-441, Cowboy CB4500, Cobra Class 4) use System 7x3, 7x4 or 794 needles, which are about 2.6 inches from the butt to the end of the tip. The walking foot Juki 1541 and 1508 use System 135x16 or 135x17 which are about 1.75 inches long. The LU-1508NH uses a 3/16" longer System 190 needle. These are all much shorter than the needles 441 class machines use.

Ok...yes I understand.  Not sure why I thought they use the same system.

 

So will the 1541 handle 138 thread ok?

Sorry for answering out of sequence. I am just catching up on this forum.

The DNU-1541 is a lighter duty and weight version of the LU-1508 series. It uses a horizontal axis M style bobbin that is 25.5 x 10mm. The 1541 uses standard walking foot system 135x16 and 135x17 needles. They max out at 3/8" and #138 thread.

The LU-1508 is the follow-up to the discontinued LU-563. They use "double capacity" U size Juki bobbins that are 28mm x 11mm in a vertical axis hook (drop in). The double capacity is referring to the standard G size bobbins used in the Singer 111 walking foot machines. 1508N and NS use System 135x16/17 needles. The 1508NH uses longer System 190 needles, allowing it to sew almost 1/2 inch with up to #207 (T210) thread. Some dealers alter these machines to use easier to find and shorter System 135x16&17 needles.

* going to begin making my own..getting harder to find my size here..specially in sandals or work boots..baskets etc,I destroy them in less than a month, maybe I should lose weight, and yet I walk light for a big guy..but the new kind of soles either spilt across the foot or collapse inside.

Have you tried jallatte safety boots, they are worth the money, but not quite as good as they were in the 2000-2010 period, best selling boot to the oil industry who give them a bit of stick

Great information.  It certainly clears things up for me.  I like the idea of the bigger drop in bobbin but I may have to settle for the liggter system.  Have an opportunity to pick up a new 1541S complete for a very good price and if it will sew T138 it should serve my needs.  

Thank you

It really boils down to what you need to sew and how many machines you can afford to buy. When I first began sewing I had one machine that was inadequate. So, I bought another head that would drop into the same table and just moved the knee lever to fit either head. Later on I bought another heavier duty machine that still dropped into the same table but required a different knee lever. Then I got into the big machines.

Great story Wizcrafts...

I made the purchase of a DNU-1541S with servo & table yesterday.  Drove 3 hours both ways to the owners home.  Have to say I'm not super happy with the deal that went down.  The problem with investing travel time in used equipment is that it suggests you are committed to bringing it home and reduces your ability to negotiate.  This machine did not sew when I arrived.  I brought thread and sample leather to evaluate it with. Spent 2 hours attempting to get it to make a stitch.  Its a newer machine and should work pretty well without a lot of fanfare but that was not to be.  Finally got it working and did bring it home but it was a painful experience.  Spent the evening cleaning and lubricating.  Top tension wire spring and pulley needed fixing, there was no tension release rod for some reason so I made one out of a modified 441 # 27 needle and generally got it work better but it lays down an ugly back side stitch with 138 thread and # 23 needle.   Achieving sufficient top tension is challenging.  Event after wrapping the thread around and around the guides (as shown in the manual) plus a few more turns and a highly tightened tensioner but still not enough.  #T90 thread is in there now and seems like a better fit but I'm still working out the tension details...Really ugly bottom stitch so some further adjusting to be done or is this just how these machines are?

I think maybe you could / should start a new topic related to your machine. Add detailed photos of your thread path from the spool to the needle, what the stitching looks like and list what needle (type and size) you are using. That way those of us with a Juki 1541S maybe able to guide you through setting the machine up so it sews properly. Who knows what was done before you got your hands on it.

To answer your question the Juki 1541S will sew a very nice consistent stitch forwards as well as backwards in the same holes.

My experience with bird nesting is that it has more to do with bobbin thread tension issues then top thread tension as long as all the tensioner parts are there. A lot of times it is as simple as the bobbin was been place in the bobbin holder incorrectly so the bobbin thread is unwinding in the wrong direction. Done that more then once when I was in a rush or not paying attention. The needle size should be a 135x 16 for leather or 135x17 for fabric and according to the Toledo Sewing Chart ( https://www.tolindsewmach.com/thread-chart.html ) you should be using a size 22 / 140 needle for V138 thread.

Maybe posting a photo can help. I will say the top tension knob is highly unlikely to need much tension. With either style of tension plate offered.  I mean they do make thin tension wire springs, but don't think its a standard issue, rather the opposite. 

Its interesting and a bummer to hear that the tensioner doesn't release. Or did not until your repair. I would call and get a few factory parts in short order. Sure cannot hurt a thing. 

With all the excitement it sounds like your on a good path. 

 

Good day to ya
