jeeperaz Report post Posted March 23, 2009 I have a 31-15 that I've refreshed and tuned/timed. Now I'm completely confused about needles so I'm asking for suggestions. I'd like to purchase Schmetz brand but can't seem to figure out the system. Can anyone tell me what they are using and where they purchased them? I'd like to order leather specific needles with various types of points but I can't seem to find a place that offers options. Quote Share this post Link to post Share on other sites
