Members Starwind0 Posted December 24, 2024 Members Report Posted December 24, 2024 Bought an adler 767 on marketplace Having issues with the thick nylon thread snapping. I just got the machine to work with my dryer plug. https://imgur.com/a/pFK1U68 The thread any nylon was selected by the industrial sewing machine store. So they should be the right size. Works fine till I try to do a thick piece of leather. Then within 3 stitches it frays and snaps at the spool side. Decides to open it up and the wick holder stuff crumbled.. not sure what part that is as the manual Is well below bar. I don't think the wick was in working order and can't figure out what to do. Far as the other issue I've adjusted the tension wheels but I don't have a half clue what I'm doing and can't find any good videos on it. If it's so loose I see the knot at the bobin side it works. Any tension and it frays. Using dotech 134x35 dia dp x 35 dia 23/ 160 cutting tip needles. 207 nylon thread Quote

However this maybe difficult as the 767 is only rated for a 134-35 #22/140 needle as per the spec. which means it is only rated for a take V138 in thin stuff or V92 in thicker /tougher stuff. The reference I used was the Duerkopp Alder manual located on page 8 ( https://partner.duerkopp-adler.com/commons/download/public/767/B_767_EN.pdf ). kgg Quote
Members shoepatcher Posted December 29, 2024 Members Report Posted December 29, 2024 #207 a little thick. Only run it on the needle thread. or go to #138 on both top and bottom. glenn Quote
