Maybe this Adler burned at Fahrenheit 451, the temperature at which insurance claim paper ignites. Montag!

Which machines do you use Ceroxylon with?

Try using liquid silicon lube, which is sold in quart bottles by most industrial sewing machine dealers.

Nope

No. Only the zipper and edge tape feet normally have teeth on the bottom. The rest are usually smooth. Walking foot machines we use in leather work usually have triple feed, where the needle, inside foot and feed dog move in synchronization, as the outside foot raises and lowers to allow feeding motion or stop it. There is no need for rollers on w.f. machines.

Look at some of the type 227 cylinder arm machines. They are usually medium duty walking foot machines with about a 3" diameter arm. They take the same presser feet as most standard walking foot machines made by Singer, Juki, Consew, Chandler, etc. Capacity is typically 3/8 inch, using #138 thread.

Precisely! I have two of them with different useful spacings. Roller feet are for straight stitch, single foot machines only, not walking foot machines. They allow the top layer to feed smoothly, without dragging on the bottom of the presser foot.

There are outside feet that have a steel edge guide that is spring loaded. They come in various spacings from the center of the inside foot (and needle).

The feet you have a a good fit for cotton and linen and even denim. The teeth on the bottom help to hold the material firmly. As for other types, get you some piping sets and piping cord to match. Piping feet have radius cut into both feet, or just the inside foot, depending on the style. You choose the size by the diameter of the cord, plus the thickness of the wrapping material. Next, get a left and right toe zipper foot set, an adjustable swing-away edge guide and maybe some spring loaded edge guide feet. There are literally dozens of different presser feet for walking foot machines, like the 206, which is the same feet as originally used on the ancient Singer 111w155.

Nice work Ferg. I'm glad that it sews. How long is the maximum stitch length at 1/8 inch thickness?

I find that by adjusting the inside foot to meet the feed dog slightly after the needle passes below the top of the dog, the reverse stitches more closely match the forward ones. I do this with no material under the feet. Try altering the point at which the inner foot makes contact with the leather, in relation to the tip of the needle making contact.

The Consew 206RB is a triple feed walking foot machine. The -1 is the first generation and won't have the great features now present on the -5 model. Still, it will sew into 3/8 inch of leather, using #138 bonded nylon thread and a #23 leather point needle. Be sure you test the machine to see if it sews properly. Bring some leather with you and see how well it handles it.

The 555 is a high speed garment sewing machine. You'd have to slow it waaaaay down, or replace the motor with a servo motor. Then, you would need a roller foot conversion kit to feed leather. After all that, it would still be limited to no more than #69 thread, sewing through about 1/4 inch of soft garment or upholstery leather. It would never sew a serious holster, or a dog collar, except for those made of webbing. It could however be used to sew leather vests and skirts, or to replace zippers in fairly thin jackets. Machines like the 555 are used in garment factories, where they sew day in and day out, at 5,000 rpm, until they wear out or seize. The machine sits on top of an oil pan and uses an oil pump to distribute oil to the critical parts, top and bottom. To get the oil to the ends of the wicks, you usually have to spin them a at least 2000 to 2200 rpm. This works out to about 35 stitches per second! Most of us sew at an astounding top speed of only 5 or 6 stitches per second. When I spin a machine up to 10 per second (600 rpm), smoke comes off the leather and the needle. So, what leather items do you intend to sew?

Try retarding the hook slightly, so it picks off the loop closer to the eye of the needle, as it ascends.

The #25 needle is best used with 4 cord, not 3 cord linen. Go down a size. Shorten the stroke of the check spring and reduce its spring tension a bit. Remove the throat plate and watch the loop as it forms and the hook approaches it. This can reveal a lot about timing problems and needle height.

This may be a combination of one size too small of a needle coupled too little top pressure. You can use smaller than standard needles if you increase the foot pressure, by screwing down the round threaded cap on top of the head. Do this until the leather stops lifting with the needle. Increasing the needle size by one may also stop the lifting, possibly without as much extra pressure screw adjustment. Are you using Schmetz type 794 needles?

Eric; When do you find time to do leatherwork?

Here are some things to check and if necessary, change... Remove the thread from the needle for now. First, make sure that the jamming hasn't retarded the hook. Remove the throat plate. Rotate the wheel towards you until the needle reaches bottom dead center The hook should be slightly behind the needle at this point Rotate the wheel slowly until the needle raises about 1/8 to 3/16 inch above BDC, then stop The hook should be in the center of the cut-out scarf in the needle, about 1/8 inch above the eye. If the hook is still behind the needle after it has ascended 3/16" and if by the time the hook meets the needle, the eye is above the pickup point, the hook has been retarded by the jammed thread. There is an adjustment accessible from a steel disk covered hole in the base of the machine, on the lower front of the right side of the body. I have done this adjustment, but don't have my similar machine at home to guide you any further tonight. It is also slightly possible that the needle bar has moved up from the shocks, placing the eye too high for the hook. Rotate the wheel until the needle and its securing screw are fully visible above the base of the machine Loosen the needle screw and lower the needle about 1/8 inch Tighten the needle screw to secure the lowered needle (don't lower the needle farther down than the screw!) Rotate the wheel and watch the position of the needle's eye in relation to the hook, as it ascends from BDC. If the lowered needle places the ascending needle's eye about 1/8 inch below the hook, that may be your problem. Thread the needle, hold the top thread up and rotate the wheel slowly, watching the formation of the loop as the hook approaches it. If the hook picks up the loop in forward and in reverse, at the stitch length setting you are accustomed to using, lock in this new position of the needle bar. To reposition your needle bar. Remove top thread Unscrew two large screws holding face plate to end of body. One is on top-right, other is on bottom left corner. Carefully pull off the face plate and set it down. Locate the needle bar and identify the two screws that lock it into position on the crank that moves it up and down. Rotate the wheel to lower the needle until the tip just reaches the top of the feed dog. Loosen the needle set screw and move the needle back to the top of the mounting hole in the needle bar and lock it in. The tip should now be about 1/8 inch above the feed dog. Using the proper screw driver or Allen key, carefully loosen the two set screws that secure the needle bar to the crank arm in the head Lower the needle bar slowly until the tip of the needle is just level with the feed dog. Ensure that you haven't rotated the needle bar while lowering it and reposition it if necessary so the needle's eye faces sideways, with the needle set screw facing front. Tighten the two set screws as much as possible to lock the bar into this position. While the face plate is off, get a precision oiler and place a drop of oil into each oil hole on the crank arms inside the head. Reinstall the face plate, making sure you hook the tension release lever over the tension release stud that sits 2 inches under the top tension disks. Thread the top as per instructions that came with the machine. Make sure that the needle is installed with the scarf over the eye is facing due right. Rotate the wheel counterclockwise and see if the hook forms a decent loop and it gets picked up by the hook. Replace the throat plate and resume sewing. To avoid jamming thread under the work, hold back both threads for a few stitches when you start sewing. If you can't hold both threads, at least hold the top thread steady, to keep it from getting drawn under the throat plate.

I do a double loop around the bottom disks, then back off the adjustment nut. I lowered the thread guide in front of the top tensioner to get more thread inside the middle of the butterflies. Oh those butterflies! Where is my spaghetti strainer?

Now you know why most experienced sewers do not recommend buying old iron sight unseen, or untested on one's own material, or sewn off by the seller. An inexpensive but damaged machine, especially one missing important parts, is going to cost much more than the buyer expected. If this machine had been sent to a dealer for these repairs, the cost would rival that of a brand new walking foot machine.

Almost any triple feed walking foot machine can produce that result, using either #92 or 138 bonded thread. Common brands include Consew, Chandler, Juki, Brother, Singer 111 or 211 (very old, out of production), Cowboy, Cobra, Techsew, Econosew, Sailrite, et al. Most of these machines have a large bobbin and normally take system 135x16 needles. They are capable of sewing up to 3/8 inch of real leather, with #138 thread and under. Sometimes, you can use up to #207 thread, with a #24 or 25 needle. I can also sew this kind of work on my Cowboy CB4500, but it takes a lot of dinking with pressures and tensions to use such thin thread on it.

I'm pretty sure that the entire assembly is sold as a kit, as well as individual parts. That would include the throat plate and special presser feet, as well as the binder.

I believe that Toledo Industrial Sewing Machines sells those parts. The phone number is 866-362-7397

On the machines that have a reverse lever, I often feather the position of the reverse lever as I watch the position of the needle, as it descends. This works best on the big 441, Adler, or Pfaff machines, which have a single lever for both direction and stitch length. Once I find the correct position in reverse, I sew a couple of stitches backwards. On the non-reversing machines, I either lift the feet and pull the material towards me about two stitches, then stitch through them to lock the stitches, or when convenient, I do the Poor Man's Reverse, spinning the work 180 degrees. Note, that if you are using a single toe presser foot, turning the work 180 may cause it to fall off the material, interfering with the feed mechanism. If that is going to happen, I use the lift, pull back and stitch forward technique. This is how I learned to sew on an industrial machine (Singer 31-15 or 96k40?), in the 1960s, in my Dad's tailor shop.
