Adler 169-73 Binding kit in Leather Sewing Machines Posted September 27 · Report reply Hello guys! @nylonRigging Those are some serious skills that I can only admire to! Thank you for the thorough explanation of the process and those little tricks that you suggested. I actually managed to get some inside curves while I still had the binding attachment attached to the machine but never managed to get is as clean as you have showed in the example. I think it's mainly because of too many layers that I have, even when sticked together I found it quite hard to make the material and binding work together well. (thickness of everything is around 6.5-7 mm. /1/4"/) That's why I decided to leave the binder for now and do the 'binding' manually in two steps. It takes more time for sure but I find it a bit easier and also manageable for me and my skills so far. Those inside turns that I showed earlier in the thread are done the second method but I found my mistakes and have improved ( a bit) although I have not taken photos. @Michiel Thank you for the suggestions! I redid the timing of the machine and also rethreaded the machine. Thread 20 worked like butter even with Needle 120! (I also bought 140 because I thought that's the issue before) I'll leave some photos of some example pieces.
