What size of thread and needle size combination are you using? In thicker / tougher material you will probably have to go up one size above the recommended needle size.

Members shoemaker4 Posted November 4, 2022 Members Report Posted November 4, 2022 (edited) I have both a 1541S clone (with the dual pretension assembly from a 1508 which enables my 1541 to tension #207 and #277 top & bottom) and a Portable Walking Foot the Portable is a great Binding Station and the true value in it is in being a Walking Foot Zig Zag. That is just a unique value in and of itself. I see the Portable as more-so a complimentary machine to pair alongside a dedicated compound feed like a 1541/206Rb/111w etc etc. the later 1541's are quite possibly the best compound feed machines in their respective class. I've sewn on the newer pneumatic 869's and LU-2810's and I didn't necessarily prefer them over the 1541. They are more "featured" machines sure, but they all completed tasks to the same degree. If there is something a 1541/1508 cannot sew it's time to get a 441 Class machine. Like I said mine has the dual tension assembly from the 1508N, most of the JUKI models only have the single tension pre-tension unit. Sailrite's Portable is nice, the metal tolerances are better and you can truthfully swap their parts into a REX/TUFFSEW/OmegaSew/Sewline etc etc. I'm in process of adding Posi-Pin to mine. There is utility in the Portable Walking Foot but it will need another $300-$600 to be machine-hacked into being useful. I think it's best as a complimentary machine though.

A good thread versus needle size chart can be found on the Toledo Industrial Sewing Machine website (www.tolindsewmach.com/thread-chart.html). kgg Ahh, well, when I use the white bonded polyester thread that came with the machine everything is working now. When I use a bonded nylon thread is when it’s gets shredded. needle is a 20 and the thread is 92 for both kinds. I really wanted to be able to use the nylon as I thought that would be better for leather, but I could be wrong. Regardless, is there something I need to change on the machine to run the bonded nylon? Bobbin tension?, needle size? as you said, tension? It is getting me rather frustrated with my brand new machine, which is attached to a table with a speed reducer and servo motor. I can tell you that the setup, while not a compound feed, is really very nice. As long as I can get it sewing. And like I said with the polyester, no problems. I even got the forward and reverse almost perfect! Chip Quote

Bonded polyester is usually a softer thread which is great for items that are going to be exposed to UV and chemicals like bleach. Bonded nylon can be stiffer with darker colored thread being stiffer with black the stiffest. A lot of thread problems can be related too: i) poor quality needles having burrs. Buy brand name needles.Also check that the needle is properly inserted and aligned squarely. ii) needle deflection causing the needle to rub on the presser foot or feed dog which may have a sharp edge. Check for rubbing, smooth out sharp edges and maybe move up a needle size to eliminate needle deflection. iii) poor quality tensioners. iv) poorer quality no name brands that the thread often comes off the spool more like you were uncoiling a wire spool with too much coil memory. Buy brand name thread. v) poor thread tension on the spools of thread particularly the 8 oz thread spools size. Buy brand name thread. vi) incorrect head height from the top of the thread spool to the top guide hole of the thread stand. A rule of thumb is the distance from the base of the spool to the top guide hole of the thread stand should be 2.5 times the height of the spool of thread. Re-located / readjust thread stand. vii) to steep of angles from the top guide hole of the thread stand to the sewing machines thread guide pin. Ideal is that the thread enters as close to horizontal as possible into the sewing machines thread pin. An example of how this can be done is mount the thread under the table as I done on a table mounted portable zig zag walking foot. Note how the thread comes through the table top and the thread spools one for the bobbin and one for the top thread are mounted on the K-leg.

Members ChipperBags Posted November 5, 2022 Members Report Posted November 5, 2022 This is the thread when the shredding happens. I would linked it, but I don’t know exactly how to do this. It was from Amazon. Desirable Life Bonded Nylon N66 Sewing Thread 1100 Yards Size #92 T90 280D/3 for Leather Denim Hand Machine Craft Shoe Bag Repairing Extra Strong Heavy Duty High Temperature Resistant Waterproof Sorry about the font. I see your extra long feeds for the thread. I think this stuff might need to actually spin off of the cone. It feels sturdier than the polyester. It probably twists to the point of breakage and then the hook nicks it and that’s all she wrote. Makes sense. Thanks, kgg! Chip Quote

I would suggest: i) you purchase a brand name thread like American & Efird either directly ( www.amefird.com www.amefird.ca ) or from places like Wawak (wawak.com wawak.ca ) or even Sailrite. A&E sewing threads are made in both the US and Canada and are quality threads. I have never had any problems with A&E threads in any of my machines. ii) readjust the bobbin thread tension by doing the drop test. When you go from one type of thread (bonded polyester to bonded nylon), change thread size (V69 to V92) to another or change thread manufacturers you should or at least recheck the bobbin tension. If you have to change the bobbin tension turn the tension screw in very small amounts like 1/16 of a turn on the screw and do the drop test again. Any chance of posting a photo of your top thread path from the thread spool to the needle it maybe helpful. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver

MtlBiker Posted November 5, 2022 Report Posted November 5, 2022 @ChipperBags - In case you're using an iPhone, I've been using a program called "Image SIze" by Codenia.com for a couple of years now. It's great for reducing image sizes for posting to websites. I also have their "Batch Resize" for doing more than one image at a time. Not free, but very reasonable purchase. From the last photo you posted, it looks like your thread is NOT correct through the first pin. It looks like it's going straight through when it should be in one hole, back around the post and out through another hole. I understand that's a new machine for you... have you followed the instructions in the excellent Sailrite manual for threading?

I will double check the post threading… I thought the two holes were only used on the Fabricator, Juki 1541, Consew 226R and other full indies. Admittedly though, no, I have not checked. Simply watched videos. And I may have skipped a step. Thanks, Chip Quote
