Singer 20U and Premier Chainstitch machine question
Wizcrafts replied to SilverForgeStudio's topic in Leather Sewing Machines
That "Premier" looks to be a Blind Stitch machine, for hemming trousers and lady's skirts. That is its single function. It can only be used on cloth and has a curved needle. Typically they use very thin invisible thread. -
Cheapest Machine to Sew 1/2"?
Wizcrafts replied to MedusaOblongata's topic in Leather Sewing Machines
Your best sewing machine option that can actually sew together 1/2 inch of veg-tan leather is the Cowboy CB3200. It can do this with up to #346 bonded thread. You can get an idea about the diameters and strengths of various sewing threads in this needle and thread chart. There is a flat slotted plate available for this machine and a flat table attachment, both at extra cost. The machine sells for $1895 plus shipping, so it is within your stated budget. If you go this route, buy extra packs of smaller size needles to use with thinner thread. They are outlined in the needle and thread chart. The smallest available in leather point for this machine is a #23 (160), which works great with #138 top and bottom, or even a combination of #207 on top and #138 in the bobbin. If you want to sew with thinner thread, like #92, you'll need a #19 needle, which is only available in round point. Ditto for a #18 needle to sew with #69 thread (for wallet interiors). I hope this helps.- 6 replies

JUKI 563 thread snagging on bobbin case
Wizcrafts replied to matcanada's topic in Leather Sewing Machines
One suggestion is to replace the bobbin case and shuttle with a new part. The other is to add slack to the top thread by experimenting with the check spring tension, travel and screw position in the curved slot. You'd be surprised how much influence those settings can have on bobbin case vs top thread problems. This is especially true if the top thread is very tight going around the bobbin case. Adding slack relieves the tension and may allow the looser thread to avoid getting caught in the slit in the case. -
The tension assembly has a steel tab on the back side that can be bent in or out to affect the slack in the tension release system. If there is too much slack, you have to move the feet higher to get it to release. You can pry the bent tab so it has a minimum of clearance between the rod in the machine and the pin in the tension disk unit. The entire unit can be removed if necessary to adjust the steel tab. It is held in by a screw on top and a screw on the bottom area of the head, to the right of the (lower) check spring disks. The bottom screw holds in the check spring shaft and sets the spring's return force.

repair help with my Singer 96-16
Wizcrafts replied to gunnerdiego's topic in Leather Sewing Machines
That is a domestic/household sewing machine needle. It should not be used in an industrial sewing machine except in an emergency until you can buy the correct needle system. I think that your machine may use System 16x231 (DBx1) needles. They are very common in straight stitch machines. If not, perhaps DBx5 or 134. All of these needles have totally round shanks.- 13 replies

I would remove and clean/polish the tension disks. Then inspect the bobbin tension spring for a thread fragment. Also check the bobbin to ensure that it doesn't have a thread stub sticking out, or windings crossing over other windings. Check the thread cone for cross-windings, or knotting along the path to the needle. Clean/replace the needle.

One sews up to 1/2 inch while the other sews over 3/4 inch. The pressure springs are heavier on the Class 4 and are able to hold down thicker stacks of leather than the 3200. The Class 4 has a 16.5 inch arm compared to the 10.5 inches on the 3200. Finally, the Class 4 and CB4500 are able to actually tension and pull up #415 bonded thread, which the CB3200 may not be able to do without difficulty. Regarding accessories, if the CB3200 is fitted with a raised (holster/stirrup) throat plate, there may only be 1/8 to 3/16 inch alternating height left for leather to be sewn. That's not much thickness. It is best used on projects that don't need to be raised to clear shapes protruding down close to the left side of the needle.

Is the hand wheel supposed to be super hard to turn?
Wizcrafts replied to JC2019's topic in Leather Sewing Machines
The brake (not break) is a curved piece of cork that's mounted inside the motor and is controlled by the activating lever. When the lever is all the way up, the brake sits hard against the armature. As you lower the lever, the brake moves away, just before the motor starts powering up. The range of free motion is limited. After that point is passed, the motor is power driven until you remove your foot from the pedal. Then the brake stops the motion quickly. The brake assembly is secured by two screws and is removable if it bothers you, or you sew so slowly that it doesn't matter. It can also be filed or ground down to get more slack. If you care to share a photo of the motor we can probably help with its operational details. Use the lowest resolution your camera allows for the smallest file size. -
The Singer 241 series are high speed factory production machines, meant to be run at several thousand stitches per minute (spm) to distribute the oil to all the wicks. In the case of the -13, that speed is 4300 spm. Compared to the Singer 241-11 and 12, the -13 has a courser and wider tooth feed dog, with a matching throat plate, higher foot lift, longer stitch length, longer needle bar stroke and longer needle system and I believe a different needle bar. There may be more differences inside and outside the machine, including the upper tension spring. The specs for all three are shown in the Singer 241 manual. Note, that all three have a factory maximum needle size of #21 (hence, #92 bonded, or Tex 105, or button hole thread). Using larger needles for larger thread requires modifying the bobbin case with a grinder and file, as shown in this video.

You should contact Adler USA about a replacement eyelet, or just remove what's left, polish the edges and live without the eyelet.

Most clutch motors have a big bolt on the right end, in front of the output shaft, which can be adjusted for more or less free play. This free play works with a coil spring that causes the control arm to stay up until you push down on the floor pedal. Tighten up the coil spring to make sure the arm is all the way up in idle, then back off the adjustment bolt until you have enough slack/free motion to feather the clutch. If the motor wants to go off to the races despite your adjustments, place a tennis ball under the toe end of the floor pedal. Then buy a smaller motor pulley that fits the shaft on the motor and a new v-belt to match the longer reach. If the motor is still grabby, open it up and smear a thin coat of light grease on the clutch pad to let it slip a bit. Unless you have restless leg syndrome, you should be able to learn to feather the clutch for slow speed operation. It's the same as driving a clutch car.

The leather used in clothes is usually chrome tanned and tumbled until it is soft. We call this Garment Leather. In the case of leather jackets, they often use a thicker Chap Leather. You can strengthen it by gluing a strong lining onto the flesh side. The lining could be heavy cloth, or another layer of the same leather, or a denser type of leather. For instance, belts and holsters are made with vegetable tanned "carving" leather than is dense. This leather can be shaped and stamped and it holds its shape and any impressions. Chrome tanned leathers do not hold a shape or take tooling impressions.

repair help with my Singer 96-16
Wizcrafts replied to gunnerdiego's topic in Leather Sewing Machines
I normally use a #18/110 needle with #69 (T70) thread when sewing leather or webbing. It is less stressful on the thread going through the eye. Try this before wasting more effort troubleshooting the thread shredding problem. You can get away with a #16 needle and #69 thread in cloth because there's less friction.- 13 replies

Is the hand wheel supposed to be super hard to turn?
Wizcrafts replied to JC2019's topic in Leather Sewing Machines
You can determine whether or not the motor has a brake by unplugging the motor and removing the upper belt from the machine, then right hand wheeling the speed reducer's big pulley under the table. Alternate between leaving the floor pedal fully up, then slightly depressing the floor speed pedal with your left hand. If there is a brake it will he very hard to reducer with the motor (off) in the up position of the pedal. Slightly depressing the floor speed pedal would release any brake and allow the pulley to turn with very little effort. The actual range of free motion on servo motors tends to be minuscule, so feather the pedal. If moving the pedal, while its unpowered, doesn't get easier when you toe down, there is probably no brake. Some machines ship with a little plastic bag of spare motor parts, including brushes and an extra cork brake. If there is a cork brake in the spare parts, your motor uses a brake! The brake is removable if you find you don't really need it to stop at your normal sewing speeds. -
I really detest the brushless servo motors that start at 100 or more rpm. They cause the machine to start and stop with a jerk. The last one I had (and replaced) was on a Techsew 2700 I bought second hand. When I first set it up, the motor caused such a mechanical jolt that the bobbin thread unloaded in the bobbin basket. I replaced it with a Family Sew FS-550s that starts at zero and smoothly increases in speed. That is the only way I go, other than regular clutch motors. More slow speed torque is achieved by installing a speed reducer. My machine came with an unattached 2:1 reducer which is now installed. I can start sewing at a few rpm and ramp up to about 1800 with the reducer installed. It starts and stops without a jolt.

Is the hand wheel supposed to be super hard to turn?
Wizcrafts replied to JC2019's topic in Leather Sewing Machines
With the v-belt disconnected from the motor, and/or the speed reducer, the machine should turn freely with the feet up. With the feet lowered the pressure spring comes into play. The tighter that spring, the harder it will be to hand wheel the machine as the feet alternate up and down. That foot pressure would be adjusted by the large threaded screw on top of the left side of the machine. This is different than the 2700 which has a flat pressure spring running along the back that is adjusted by a thumbscrew in the middle of the machine, to the rear. I should mention that if you bought the machine with a speed reducer, it will be harder to hand wheel than one connected directly to the motor. This because the reducer becomes an increaser when turning it from the machine instead of the motor. And, as mentioned in an earlier reply, your motor may or may not have a cork brake that needs to be relieved with a little toe movement to hand wheel without the motor turning over. Another point of great importance is to oil the machine thoroughly before running it with the motor. This includes opening the face plate cover and dropping oil into the tiny holes in the crankshafts and the sliding part on the take-up lever. Oil to excess and leave a shop cloth under the feet to absorb the drip. Before sewing anything important, wipe oil off the feet and the bottom of the head where the presser foot, alternating foot and needle bars come down. Only use Lily White sewing machine oil! -
Read this thread and needle chart to understand how industrial sewing machine thread sizes compare to hand sewing thread sizes. Pay close attention to the right column under Diameter. You'll see that 0.8mm is about size 554 bonded, or 8 cord linen thread. Almost every upholstery class sewing machine maxes out with #138 (T135) thread, which is .414mm diameter. You cannot sew .8mm thread into 10 ounces of leather. The lockstitch knots would occupy too much vertical space to hide them. Only the very largest needle and awl harness and sole stitchers can sew with #554/8 cord thread.

repair help with my Singer 96-16
Wizcrafts replied to gunnerdiego's topic in Leather Sewing Machines
I once owned a Singer 96k40, which was a tailoring machine similar to the 31-15. Both use Class 15 side load bobbins and have bottom feed only. The 96 is lighter duty than the 31 series.- 13 replies

Overwhelmed by leather Sewing machines
Wizcrafts replied to Starwind0's topic in Leather Sewing Machines
You really should get the quietest machine you can fine, with the best balance so it doesn't vibrate on the floor as you sew. Definitely get one with a servo motor that starts rotating from zero, rather than 200rpm. You don't need any of those controls for home. slow speed, leather sewing. They are for factory production machines that are run hard and put up wet, 8 to 12 hours a day, at 2500 rpm and up. Just find a solid, slow speed, manually oiled, non-electronic, triple feed, (hopefully with a cylinder arm + table attachment) walking foot machine (like this CB341). -

I never knew there was a dealer in Waco who sells Cowboy machines. Or, is that a private sale of a used machine? -
Overwhelmed by leather Sewing machines
Wizcrafts replied to Starwind0's topic in Leather Sewing Machines
Leather goods manufacturers don't necessarily use one single machine to produce their wares. Travel bags like those you linked to (India) might require 3 or 4 different types of sewing machines, plus one or more kick presses for rivets, scuff feet and decorative spots. I will hazard a guesstimate that these bags are sewn using a combination of flatbed and narrow cylinder arm walking foot machines and a tall, narrow post bed machine which could have a roller feed, or might be a chainstitch needle and awl machine like a Puritan, with a minimal footprint post. If you are thinking about making messenger bags, or briefcases, plan on buying flat bed, cylinder arm and post bed machines. -
I've done that a few times and then took work home and got paid on a piece work basis. I made more that way than working hourly at the shop. Plus, you can work at you own pace at home. One such gig paid for a walking foot machine in one month.

The wax pot was there for linen thread. Before there was bonded nylon/synthetic thread, there was cotton or linen thread. Machines that were built to sew heavy and hard leather used left twist Irish linen thread that needed to be waxed on the way to the needle. The wax had to be in liquid form to avoid clogging the needle, so pre-waxed hand stitching thread wouldn't work. The liquid wax dried in the holes around the lockstitches. This is the same technique that is still used to sew soles onto shoes with curved needle/awl machines and Randall Lockstitch machines. The bottom line is, if you aren't going to sew with Irish linen thread, you don't need a wax pot on top of the machine! Bonded/pre-lubricated thread is sewn as is.

Nothing in particular. There was a bee in the house. I deleted the comment.

What new box? This machine is obsolete. The only way to get an authentic was box would be to remove it from another 97-10.
