Members Captjoey Posted January 15, 2019 Members Report Posted January 15, 2019 I sew boat canvas but hope to get some advise on this site. When I make a 90 turn I get a loop on the next stitch on the bottom side. Does ok with 45 degree turn or 135 degree turn. Tech worked on machine and could not fix it. Someone else told me it was in the take up spring but I have tried different combinations to no Avail. I am using a #18 Needle and Solarfix PTFE thread 2200HD/3-T8. JUKI 1541-S machine i think about a 2010 model. Photos are under side of material sewing around the horn clockwise with two pieces of weblon regetta. All others functions seem fine, pretty stitch and even on both sides except when making 90 turn. HELP !!! Quote
alpha2 Posted January 15, 2019 Report Posted January 15, 2019 Are you letting the needle come up a 1/4" before making the turn, to be sure the hook catches the thread? Quote So much leather...so little time.

kgg Posted January 16, 2019 Report Posted January 16, 2019 I am not familiar with the thread you are using as it compares to "V" size but since you are using a #18 needle I am going to assume it's V69 or max V92 equivalent. If it thicker you will need to go up to the correct needle size. What I found best for my Juki 1541s was to have the needle on the upstroke, stop the machine raise the foot off the material using the knee lift and carefully turn the material 90 degrees so as not to bend/deflect the needle also will I keep my bobbin tension normally a little more on the high side of tight. 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
Members brmax Posted January 16, 2019 Members Report Posted January 16, 2019 (edited) As you know, If you consider the needle is best to still be in the material when you turn, is easier. So with that if we take a look, and it can be a practice thing with the knee bump/lift. I mean getting use to the feel for presser foot lifting a lot! yet keeping the eyelet below the material. Its going to be somewhat acquired and then additional acquirements in material type changes. Good day Floyd Edited January 16, 2019 by brmax Quote
Members katit Posted January 16, 2019 Members Report Posted January 16, 2019 This excersize was pretty easy for me on my machine. Stop with needle jast starting to raise, just slightly lift feet and turn material. Voila! What puzzles me is that author doing exactly the same but not getting desired result. And look at other corners (not 90) - they all look good. OP, anything you do differently with those corners other then how much you turn your work? I wonder if there is some kind of misadjustment on machine which opens top thread tensioner too early? But why other corners look good is a question. Quote
Members Captjoey Posted January 16, 2019 Author Members Report Posted January 16, 2019 First of all thanks for the responces. I am pretty sure this is a problem with my machine and not caused by techinique. I have no issues with the machine that I use at work. This is my Home shop machine. I've had several people sew on it and they all get the same result. The tech adjusted everything he could think of and could not get it fixed. I'm just before taking it to a JUKI service center but that is a 4.5 hr drive one way. Keep the ideas coming. Maybe we can figure it out Quote
Members katit Posted January 16, 2019 Members Report Posted January 16, 2019 I'm sure if you can make a video of hook and whole process - someone will help you here. It seems that top thread get's "hung up" on something underneath on a way up. Maybe it's related to how you turn and how loop just slightly angles underneath. Video of this would help for sure. Quote
Members brmax Posted January 17, 2019 Members Report Posted January 17, 2019 Im going to have to ask is the machine the same as your work machine. Also is the tech the same company and or person as your work calls on. In any case I thought it strange most all issues were in corners of the same turn. So with some more or lots more questions, particulars can this same test be made with both directional turns. In this I would deffinetly bump up to a 19 to better assess possibilites. In that Im familar with solarfix and do use 18, but were not discussing needles primarily. We really could look at positions of the tension spring and take up lever when we know needle eyelet is still below the material but on its continued way up. Just doing a straight line stitch would be the choice. Its tough doing armchair diagnostics. So a big thanks for the pics but its gonna take much more and or a video. Remember these issues are exactly what this forum section is all about, you are at the right place! Good day Floyd Quote

The machine I sew on at work is a Consew 206RB-5. The person who worked on my machine is a traveling repairman who works on the ones at work. Loop happens on left and right turns. I will attempt to make a video soon of the process to better help. Stay Tuned !! Thanks CaptJoey Edited January 17, 2019 by Captjoey Quote
