mlapaglia Report post Posted January 7, 2014 I know this is the wrong forum but I need a quick answer if possible. 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 Quote Share this post Link to post Share on other sites
dirtclod Report post Posted January 7, 2014 (edited) I don't have a Boss but on my machine, has a motor but i can generally tell from the sound it makes going through the leather. Not sure how to explain it but it's different. Edited January 7, 2014 by dirtclod Quote Share this post Link to post Share on other sites
