Turn the speed dial up a notch. You'll still be able to feather the pedal for slow speed, although it will be a little touchy until you get the hang of it. A 1:2 speed reducer is also a 2:1 torque magnifier.

Rather than promoting one particular seller, here are some Google search results for "Pull The Dot snap fasteners." Some eBay sellers have them in as little as 10 sets. Just make sure you read the specs to get the right post length for the project at hand. Some have very short posts for canvas. You'll want longer posts for use on holsters and sheathes.

The spindle doesn't have any threads. What it does have is a round tab inside one side of the cap on the end. That tab fits in the threads cut into the back of the top shaft. If those threads are intact, when you screw in the spindle you may have to loosen the cap and inside screws that have a very strong, small spring with a stud or ball bearing on the end. There is also another screw on the opposite side of the housing in the top of the head. It sets the maximum stitch length. The process is to determine which side has the cap screw. Remove it, then unscrew the inside screw with the spring until it is almost out. Rotate the shaft so you can get to the other screw and back it out. Now you should be able to twist in the spindle shaft. With it in all the way, screw down the spring loaded screw, then secure it with the cap screw. Set the maximum stitch length with the screw on the opposite side of that housing; usually between 4 and 5 stitches per inch. Now, you can screw the cap on the spindle out to shorten the stitches, or back in to lengthen them again.

In my experience, when the top thread is so tight that it snaps going around the hook, the timing is retarded. There's two ways to correct this. One is to advance the hook. The other is to adjust the check spring for more slack during the take-up cycle. The additional slack is normally used when sewing thick seams, or if the material is bunching up from too tight stitches. If your hook is slightly slow, the check spring adjustment might reduce the tension going around it. If not, advance the hook slightly. It's possible that the hook has too much slack in the gears so that even though you timed it correctly at rest, it retards during operation. It might even have one or both set screws loose. Or, it could be set too high in the saddle, or the slack gears might allow it to lift during take-up..

If there is a Tandy Leather store near you, shaver blade and is used to thin the flesh side of leather belts at the turnback area where the buckle goes.some of your pleather in and ask to try their hand held skiving tool. It uses a small razor blade to skive (thin) leather belts at the fold for the buckle. Maybe it will work on your pleather.

That would be tricky on manmade material like pleather. I've tried skiving Naugahyde, to no avail. It just chewed up the back side. Still, it may be worth a tyry if the OP has access to somebody with a band knife skiver.

This machine is a shoe and boot "patcher." Do you plan to work on shoes and boots (uppers only)? It can also be used to sew patches onto vest pockets and jacket sleeves without closing the pockets or sleeves. Do you intend to go into the patch sewing business? Another thing these are good for is repairing looe purse strap tabs on the sides of purses. The narrow nose can get inside where no other machine can go. Will you be repairing purses and pouches. One more task the long arm patcher can handle is sewing cue cases, or other cylindrical otems, up the arm (I call it sewing up the snout). If you answered yes to one or more of those questions, it is worth your trouble to haul it home, fix the cause of the seizure, and put it to work. Please note, that despite its robust appearance, this is a light to medium duty manual sewing machine that is entirely fed by the presser foot. The foot rotates around 360 degrees and has aggreesive teeth to grab the work and pull it to form stitches. The teeth will leave very noticeable marks on veg-tan leather.

While there are tools available commercially to punch a hole and slot, I had one made by a tool and die maker. All you need is a 1/4 inch hole punch and a 3/4 inch chisel with a sharp point. Punch the hole first. Then place the chisel blade just inside the edge of the hole facing up the strap. Line up the punch dead center from the hole along the center line of the strap, then punch the slot and you should be set.

I have the same machine and use standard size G bobbins in it. These are the same bobbins as used in the Singer 111, 153, and 211 machines and many others.

This has happened to me and many others when we have either purposely, or inadvertently increased the lift ratio of the presser and alternating feet too high. Once you increase the alternating lift, and are actually sewing something, the internal crank shafts can make hard contact with the presser foot bar, jamming the action.

The Schmetz S point is NOT available in System 135x16, which is the designated needle system for the Juki LU-563. However, Schmetz DOES make the S points in System 134-35, in sizes 80 through 200. These needles are about 1mm shorter than the standard walking foot needles and were made for certain Pfaff machines. In order to use the S points in a Juki 563, or equivalent, one must lower the needle bar 1mm, then check the timing of the hook. Some people, myself included, have been able to use the Schmetz S point needles, without any adjustments, in Singer walking foot machines that only sew forward, not reverse. The Juki LU-563 is often used with reverse to lock the stitches at the beginning and end. Sewing in reverse requires precise timing of the hook and needle. This could be a problem with the shorter needle, unless the timing and check spring were tweaked to the Tees. I would simply lower the needle bar to place the hook above the eye, as per the machine's specfs, and leave it there, only using S points, or other System 134-35 needles. The maximum sewing thickness would be reduced by 1mm.

I had a set of the original inline feet taht needed the height adjustment. I found out a couple years ago that @CowboyBob Bob Kovar got in new ones that were already the right length. They go on without requiring any further adjustment.

I got a set of inline feet from Toledo Industrial Sewing Machines, for my Cowboy CB4500, which is almost the same as a Class 4. I made a video of the inline presser feet in use. I believe that they cost about $125 or $130, plus postage. With the inline feet you can actually use the machine to sew outsoles onto a shoe, if it has 1/4 inch width before you sew and trim it.

The Consew analog servo motor sold by Toledo Industrial Sewing Machines is probably all you will need. It can be ordered with a pulley as small as 45mm. This is less than 2 inches diameter. I'm pretty sure that the pulley on your Pfaff balance wheel is at least 4 or 5 inches diameter, giving you more than 2:1 speed reduction/torque multiplication. You can install it yourself. Your local hardware or auto parts store will have a selection of type 3L v-belts to connect the motor and machine and leave 1/2 inch of slack in the center. The knob on the front of the motor limits the top speed and can be changed on the fly as you sew. I do it many times. I might start with a slow speed setting until I get to a long seam. Then, I reach down and spin the knob and it's off to the races. Still, it is possible to slow down the motor gradually from the top speed setting. It's just not as smooth on the ramp up compared to a much lower setting.

The roller feet I've had in the past had a spring that held them in position, and a screw to adjust the distance from the bottom of the wheel to the needle. I've found that they work best when the needle just misses the edge of the wheel. The farther away the wheel, the more the material/leather can lift with the ascending needle. This causes skipped stitches.

Are you referring to the Consew Premier CSM550-1 servo motor? If so, the start up speed is barely spinning. I have its predecessor, the Family Sew FS-550s on several of my sewing machines. Some power the machines directly, with a 50mm pulley, while others feed 2:1 or 3:1 speed reducers. If there is little to no load on the motor, it starts spinning very slowly. Under load I have to give it more pedal or knob rotation to overcome the resistance. The machine will still run very slowly unless I turn the limiter knob up high. Even then, the slow speed is fairly easy to control with my steady foot. One of my machines fed directly from a FS-550s is a long bed walking foot machine with a 5" hand wheel pulley. I can run the machine at 1 stitch per second with ease and it ramps up from zero smoothly. I frequently use that machine to sew patches onto the back of bikers' vests. The analog servo gives me total control over the speed. I can stop it with the needle down to turn corners.

I once owned that same zig zag machine. I used it to sew on a leather vest I made. It is best limited to #69 or #92 bonded thread. The machine in your photo has the wrong presser foot. You will have trouble zig-zagging with that foot, if at all. You need a wide Pfaff foot with a sideways slot that lets the needle move right and left. Perhaps the other foot is in a parts drawer. If I recall, that zig zag isn't very wide; like maybe 1/4 inch maximum. My recollection of the machine is that it was very quiet and smooth in operation. The feed is bottom only, which is typical in zig zag machines.

Try a different leather point shape than diamond. Sometimes a slicing wedge performs better in dense leather. This would also let you move up one needle size if tight holes are the problem. Little known factoid: Schmetz make System 134-35 needles in "S" point, which is an inline slicing wedge. They are about 1mm shorter than System 135x16/17. Sometimes they work with out any needle bar adjustment. Otherwise, lower the bar 1mm when using 134-35.

I agree that the analog servo motors have low starting torque. On the machines where I need low speed with high torque, I add a speed reducer. That cures the problem entirely. Some are 2:1, others are 3:1 speed reduction/torque multiplication. These motors and reducers came from Toledo Industrial Sewing Machines. One of my 10 machines is mounted on a table I've had since 2010. I've change the machine heads several times, but kept the table and motor. The motor is branded SewPro 500GR. It is an analog servo motor with a built in 3:1 speed reducer. That motor powers any machine that fits in the cutout through the densest leather. I tried to buy another SewPro 500GR motor two or three years ago but learned they are no longer made. Evidently, the people who made them in China went out for lunch and never came back! No motor for you!

I will be ordering a couple packs of ten!

Welcome back, Eric! We've missed your input.

In system 794, or 7x4, the smallest leather point needle available is from Schmetz. It is a #23 needle with an S point, which is an inline chisel. This needle is best used with #138 thread on top and bottom. However, you could load #92 thread in the bobbin and tighten the bobbin tension to pull the knots down inside the layers. Since you asked about using #69 thread, you *can* run it in the bobbin, *if" the bobbin tension spring will clamp it down tight enough to control the position of the knots. To run #69 on top requires the machine to be able to loosen the top tension a lot more than expected. Finally, if you can make those two adjustments, you can buy a pack of #18 and/or #19 needles in system 7x3 - round points. They will poke perfectly round holes that will look large compared to leather point needles. If the leather is dry, or dense, those needles will squeak and may even grab the leather, lifting it up as the needle ascends. This will cause skipped stitches. To offset this problem, fill the lube pot with clear sewing machine oil, or liquid silicon lube and run the top thread through it. ANybody who has a 441 type machine, including the Cowboy Outlaw, wanting to use small thread and needles in it to sew a thin project, should read my blog article about Dumbing down a Cowboy cb4500, Cobra Class 4, or similar harness stitcher.

There are a handful of machines that fill the gap between a full blown 441 clone and a traditional walking foot upholstery grade machine. These in-between machines start life as walking foot machines that have beefed up take-up parts, extra large hooks, and stronger thread tension and foot pressure springs. Some even have dual top thread tensioners. Here are some for your consideration. Most of these can tension up to #207 thread, top and bottom and sew up to 7/16 inch of medium temper leather. They can still handle thinner needles and thread so you can sew wallets, as well as tooled rifle slings/guitar straps with suede linings.

There are aftermarket feet with teeth. They are sometimes sold as zipper foot sets. I've bought them in left toe and right toe. The teeth are meant to grip zipper tape and get a good grip on leather. Just be prepared to rub out the tooth marks. There are also double toe feet with teeth that outdoor vinyl sewers tend to use. Vinyl is pretty slippery. Banners and boat covers are also sewn with toothed walking feet. Sailrite may stock the feet you need.

If I Grok your setup, your patches are 5oz veg-tan and your thread is an astonishing size 207! I sew on patches for a living and I would use #92 bonded thread, with a #19 needle, for that thickness. With this thread size you'll have no trouble hiding/burying the knots. You are simply using a thread that is 3 times thicker than the leather can conceal. I don't use #207 thread in anything thinner than 10 to 12 ounces. It dawned on me that you might be using this oversized thread for appearances only. This is known as the Topstitching Effect. If this is the case, load the bobbin with #92 or #138 thread and use a #23 Schmetz "S" point needle.You'll have to tighten the bobbin tension to keep the knots below the top surface. The #23 S point needle makes a very tight inline slice that pulls the leading and trailing edges down below the top grain. By using a smaller bobbin thread, it is easier for the bobbin thread to overlap the top thread and form locks. The #207 top thread will try to overpower the smaller bobbin thread. Back off the top and tighten the bottom on test pieces until you get it right.
