mlapaglia Report post Posted January 6, 2014 (edited) I am using a Boss with 277 nylon thread and 794-200-S needles. I mostly do belts and holsters. How often should I change the needle. Is there a way to tell when it gets dull? Should I be looking for a change on how it comes out on the back side. Its not easy going through 3 layers of 8/9 so Im not sure I could tell if it gets a little harder pushing the needle through. (and yes I know if it breaks change it.) Thanks Michael Edited January 6, 2014 by mlapaglia Quote Share this post Link to post Share on other sites
