Wizcrafts Report post Posted August 25, 2013 I now get Family Sew motors from Toledo Industrial Sewing Machines. They have a rotary speed control switch on the front and lots of power. Your Juki is a light duty dual feed machine, with a fixed needle position. It was built to sew cloth garments, not leather. Thread-wise, you'll be pushing it with black #138 bonded nylon. You'll be better off buying the more expensive, but typically softer bonded polyester thread. Sewing with #138 thread, top and bottom, requires either a #22 or #23 leather point needle. Schmetz are best, if you can get them with an S point favored by most of ussens. Quote Share this post Link to post Share on other sites
