Please post a close up photo showing how the thread is feeding into the top tension disks. Show the entire tension plate. It could be threaded incorrectly. Also, examine the thread path from the spool to the needle. See if it encounters any burrs along the way, or gets twisted around a guide or post, or gets caught under the spool, or wraps around itself coming off the spool. Gotta go to work. Good luck..

I can't help you with troubleshooting that machine as I don't have one to use as a reference.

I found a typo and some inaccuracies. Adler is misspelled Addler. Also, you included Cowboy 29 and 227 machines in the thread size 207 group which they don't belong in. You also included the CB29 in the #277 group which is way beyond it capabilities.

This Needle and Thread Chart will help you choose the best combinations.

I buy thread from different stores. Most of it comes from our Cowboy sewing machine dealer. Others come from Superior Thread, or Wawak. I still have some Weaver bonded nylon thread, but is very twisty and expensive. Your machine uses the ubiquitous system 135x16 and 135x17 needles. They are sold everywhere industrial sewing machines are sold and serviced. I buy some Japanese needles on eBay that are titanium coated and like them just fine. But, now and then I want something a little better made and buy Schmetz or Groz Beckert needles.

I do not recommend using #207 thread in that machine. I have the same machine in my shop and limit it to #138 maximum, using a #23/160 needle. The 2700 is normally used with thinner thread, like #69 and #92. It is not strong enough to regularly punch through with #207 thread. But, if you really want to use that thread, get some System 135x16 (leather pt) or 135x17 (round pt) needles in size 24. Just make sure you understand how to re-time the needle bar to the hook after you knock it out of time.

Those are oil wicks. Please stick them back inside the head and make sure they contact the needle bar and inside foot bar.

I have learned to adjust the check spring tension and stroke according to the type of material and thread I am using. My most common combination is #92 (T90) bonded nylon thread, top and bottom, with a #19 (120) needle, into about 1/8 inch of leather, plus or minus. On my long arm machine, the top tension is fairly high most of the time. This is because I upgraded the tension spring to a heavy duty type. ;-) By running not too loose tensions I get tight stitches on the top and bottom of the work. (Aside: there are exceptions where I back off the top and bobbin tensions). I find that with this machine, which has been upgraded to use a Juki U hook and take-up lever, The top thread tends to snap as it passes around the hook. I can offset this by feeding a little more thread during the downstroke by playing with the check spring stopper and its position in the curved slot. It only takes a minute or two to find this setting and it makes it so much smoother to sew. Shortening the throw of the spring causes the top thread to be more slack on as the take-up lever starts down. The position of the screw in the slot in the disks fine tunes this. A standard factory setup usually has the screw in the dead center of the disks. Rotating the disks to the left increases the slack thread tension and vice versa. As for the travel, I always ensure that the spring holds the top thread taut until the needle fully goes through all layers. I NEVER let it continue holding the thread to BDC! That is asking for skipped stitches. The needle thread should have a little slack at BDC which increases as it moves up 3/32 inch to form a good loop for pickoff time. I have literally seen loops disappear on the upstroke when the check spring throw is too long. It is easy to watch this process on a shoe patcher. All of this is my opinion, based upon my own findings with my own sewing machines. Your results may vary.

This stuff should be posted in the Off Topic forum. We try to segment our topics and this section is for technical and operational leather sewing machine issues. Off topic has other political discussions going on.

Jeff; I went through the same thing with digital servo motors. Now I only buy analog control servo motors, such as those sold here. These motors can be setup with a tiny 45mm motor pulley, or a larger 70mm. The smaller one makes it easier to feather the machine for very slow sewing. The larger one gives more top speed. I find the larger one unnecessary in leather sewing where you probably won't want to exceed 10 to 15 stitches per second flat out.

The Juki LU-562 is a Japanese clone of the Singer 111w155. It uses the same "standard" size bobbin as the Singer 111. One is very good condition might be worth 4 or 5 hundred bucks; 6 tops. The Artisan on the pedestal stand might bring 1300 or so. It is a heavy duty stitcher that sold for about $2700 new. The Tippmann could be a Boss manual sewing machine, or an air operated sewing machine, or a clicker press. Which is it?
