    If you have a lube pot on top of your machine, buy some liquid silicon lube and run the top thread through it. Most industrial sewing machine dealers have quarts in stock.

    You could ask the seller if they could sew a 1/2 inch stack of leather with the heaviest thread and matching needle they have, at the maximum stitch length, sending you a photo of the results.
  3. Wizcrafts
    This is a case of bring your own stack of leather and see if it sews that thickness and what the maximum stitch length is at that thickness.

    All of the class 153 machines are rated at #138 thread, top and bottom. The stitch length depends on the type of stitch length adjuster used in that particular machine and how you set it up. My Singer class 111 walking foot machines have a threaded rod and knob on the back of the hand wheel. The maximum stitch length is about 4 to the inch. The later model 111w155 was able to eek out 3.5 spi, using a different stitch length system. The Singer 153 uses a standard G size bobbin that does not hold nearly as much #138 thread as newer M style bobbin machines do.

    What you have there is a Union Lockstitch machine. I've owned two of them over the years. They are different from Randall Lockstitch machines (now called Campbell-Randall Lockstitch), like apples and oranges.

    Search Leatherworker.net for Adler 105-64. There should be a few discussions about the machine and its capacities.

    That's a good thing! They really got these motors right compared to the old push button styles. BTW: Did you change the image file in your signature? The usual banner is missing, leaving only a link to your website. The missing file is: kovar.gif

    It looks like a clone of an Adler 105-64

    Try swapping out the pressure springs for lighter/softer work. You don't need the extra heavy coils until you sew stacks of hard leather. It only takes a minute to unscrew the pressure screw.

    The OP already tried backing off the foot pressure, to no avail. Also, there is no separate pressure screw adjustment for the inside foot. Both feet are adjusted together with a big threaded cap screw on top of the machine head.

    Let us know how this turns out for you.

    There is a spring inside that motor that is supposed to lift the lever all the way up. Something happened to that spring. You can call one of the Cowboy dealers for assistance with your motor. Your closest dealer is Solar Leather in Texas, then in Toledo Industrial Sewing Machines in Toledo, Ohio..

    Yes, that is a standard compound (triple) feed walking foot machine, good for all types of upholstery, belts, wallets, pouches, gabs, etc. It can sew up to 3/8 inch with #138 bonded thread.

    Open up the motor end cap and see if something is binding or the brake cork is not engaging with the lever up.
  16. Wizcrafts
    See if there is a return spring on the motor control arm that pulls it up. Tighten that spring. Otherwise, you may have bent the plastic control arm. The bend would be obvious. Try straightening it out. Also, make sure there is slack in the chain from the motor to the pedal.

    Use the bottom stop bracket to set the throw of the spring. The thread should remain taut until the needle has penetrated the material. The spring tension should be just enough to hold the thread as the take-up lever starts its downward stroke. The spring tension must not override the main tension disks.
  18. Wizcrafts
    The thread should be taut until the needle meets the top of the fabric. From there it depends on the material. I usually keep the thread taut until pickoff time.
  19. Wizcrafts
    Rotate the hand wheel a little more to clear the thread from the shuttle. Also, it looks like the thread is getting caught on the tab on the bobbin case. Adjust your check spring to leave more slack in the top thread. It should go around the bobbin case and shuttle without binding, snapping or getting hung up. Your last photo doesn't show how you have threaded around your check spring assembly.
  20. Wizcrafts
    Adjust the bottom stop bracket under the check spring for more travel downward. The adjust the position of the check disks to reduce the slack to the minimum needed to go around the bobbin case and shuttle without making a snapping sound. This adjustment is done by loosening the little screw in the slot and moving the disks one way or the other. Finally, the tension of the check spring is adjusted by loosening a screw in the body that holds the shaft that the spring is mounted upon. With the screw loose, turn the shaft anti-clockwise to strengthen, or clockwise to lighten the spring action. Then tighten the screw to hold that spring action.

    Clutch motors have a large bolt on the front that can be adjusted for free play before the clutch engages. There is a spring and thumbscrew on the right side of the lever that sticks out to control the motion of the clutch. Tighten up the thumbscrew on the spring to get a little more control over the foot action and keep the lever as high as possible until you press down. If the clutch is grabby, smear a little grease on it (partial disassembly may be req'd) or sand it smoother. A well adjusted clutch motor can be feathered accurately by a steady foot. Sewers have done this for a hundred years. My Dad feathered the clutch on his Singer 31-15 for 60 years.

    In reality, you can probably get better use from a standard walking foot machine, with a cylinder arm. There are many brands that made and make these machines. Here is what a typical cylinder arm walking foot machine looks like and sells for new, in the USA. This one is a clone of a Consew 227R. These machines use a common system 135x16 and 135x17 needle and can sew up to 10mm thickness with Tkt 20 (or under) bonded thread.

    There is a world of difference between the Singer 45 models and domestic/household sewing machines. The 45 series was built to withstand the forces and pressures exerted by heavy thread and thick dense leather. Some 45k sub-classes were used to sew soles onto shoes. Others are used in saddlery. It is literally a case of apples and oranges. The 45k is a very good leather sewing machine with few parts that can go out of wack. If you plan to sew hard or thick leather, or even thick stacks of cloth, the 45k is an excellent machine. What is won't be good at is sewing thin or soft leather or cloth. The feed dog teeth are aggressive, then needles are long and the springs are very strong.

    That .heic image file requires a special, non-standard codec to open it. Can you re-upload the image as a .jpg or .png file?

    Have you asked Raphael Sewing in Montreal, aka: Techsew? They import parts that are in Metric measurements, as is forced upon Canadians by law.
