Sorry to bump an old thread. 

Does it matter if the needles are ball point or regular point? I am looking to use 207 thread in a 563 with leather.

 

Neither of those is really suitable for leather.  Both are meant for fabrics.  You want to use needles specifically for leather - of which there are a few types.  LR comes to mind offhand.  This may be helpful.

Your machine uses Systen 135x16 leather point and 135x17 round point needles. Round points are for cloth and woven materials. These needles gracefully separate the fibers as the penetrate the material. The actual holes tend to heal as the stitches are locked. Leather point needles have different configurations. All of them will cut through the leather fibers destructively, leaving room to pull up large knots from bonded thread. If you use a leather point on cloth, it may sever the fibers, weakening the material. A dead giveaway that you are using a round point in leather is the squeak the needle makes as it fights to penetrate the leather. It heats up and leather fibers will stick to the hot needle.

Buy 135x16 needles for leather! Some designs lay the stitches on angles, like hand stitching. Others sew inline, like the Schmetz S  and most diamond, or tri points.
