    Opinion on Adler 30-70

    Some replacement parts and some needles are available direct from Adler USA. Others from Europe and the UK from private sellers and major dealers. Prepare your heart meds if you need important parts. If you can buy it for under $1,500 and it is guaranteed to be in working order, grab it. Ask if there are needles included. The 30-7 and -70 use an extra long needle that is sold as 332LL LG, which are 55mm long (about 2 3/16"). Do not confuse this with system 332LG, which are much shorter.

    Singer 29-4 usable?

    Try to watch for a Singer 29k71, 72, or 73. These are among the finest and have the most compatible parts available. The last Singer patchers made were 29 K or U 171, 172 and 173. I had a 29k172 and had non-stop problems until I decided to get rid off it. That's when it began behaving as expected!
  3. The check spring travel limiter and position may help tune the snap out of the thread coming around the bobbin. The spring has to keep the top thread taut until the needle pierces the top of the material. How much longer it stays taut is up for experimentation. If your check spring mechanism has a little screw inside a curved slot, try moving the discs one way then the other. There will be a position that gives a little more slack in the top thread that should ease the tension going around the hook.

    Singer 29-4 usable?

    I was referring to the pinion gears under the nose of the arm. Those have changed dimensions and how many were used over the years. People trying to restore ancient model 29-4 machines are discovering that there aren't any readily available replacement pinions in the aftermarket. There are other moving parts that fit the early models but not later ones. It is a crap shoot to buy an ancient patcher. However, they make excellent weights and anchors!

    Singer 29-4 usable?

    I should have qualified my previous statement from 2016 where I claimed that Singer patchers are the polar opposite of production machines. This would apply where it is the only sewing machine a user has and will have to perform all of the sewing operations. They can be applied to production situations, as described by Mike, where other machines struggle and they excel. But, the patcher should be finely tuned and high quality if you depend on it to help produce goods for sale. Most discussions about Singer patchers are from people considering buying a 29-4 as their first or second sewing machine. They want to know if the machine can sew belts, straps, holsters, saddles, etc. They ask how thick can it sew and what is the thickest thread it can use. This is because the machines are so well built that they appear to be strong enough to handle all those jobs. The answers tend to disappoint the posters. To the point of the original discussion, Singer 29-4 patchers are from the early 1900s and are usually shot by this time. Their stitch length is the first thing to go, then the timing gears wear out. Some of those gears are no longer available, except from salvage machines. I personally would not trust such a machine in a production environment unless it was rebuilt to factory specs (including possibly making some new pinion gears)..

    Needle clamp for adler 30-1

    Welcome to the World according to Adler!
  7. Stu; The owner of the Cobra brand is in Ontario, California. They go as Leather Machine Company. Their toll free number is: 866-962-9880. I'm not certain if they can cut a table for your machine, but it's worth asking. Other than that, I know there are a lot of industrial sewing machine dealers in the LA area, most of whom sell on eBay. There's no doubt one of them can setup a table for your particular machine. The only IF is the servo motor. Aside from Cowboy and Cobra dealers on our forum, the eBay dealers don't normally stock motors with the very small pulleys we need for slow speed sewing and punching power. It is the nature of these motors to have much less power at starting speeds. Tiny pulleys help somewhat, but 2:1 and 3:1 speed reducers really make it possible to sew at extremely slow speed and punch through 2 or layers of belt leather. It would help if you can measure the diameter of the pulley on the back of your machine. If it is 4" across the top, a 2" motor pulley will give you 2:1 reduction/torque multiplication. This would allow a Family Sew 550s motor, equipped with a 50mm pulley, to punch through leather at slow starting speeds. I do know that the same dealer, in Toledo, Ohio, selling the small pulley Family Sew motors, sets up and sells Consew machines. I'll bet he can setup a table and slow speed capable motor and ship it to you at a lower price than you'll pay buying the parts separately from different dealers. That would likely include the proper v-belt too. The number there is: 866-362-7397
  8. This statement needs expansion. There are two commonly employed motors for industrial sewing machines: clutch and servo. Clutch motors have a mechanical cork (or other sometimes questionable material) internal clutch that transfers the motion from the always spinning motor to the output pulley (which can be various diameters). These motors have an adjuster bolt that gives or takes away slack in the pedal before it fully engages the clutch. One must have a steady foot and good toe control to be able to gradually engage the clutch to sew slowly. Most newbies to these motors miss the narrow range of semi-engagement and the motor is off the the races at 1725 rpm. Since the motor is always spinning at full speed when powered on, they generate noise and heat and eat electricity. Servo motors are electronic DC motors that only spin when the control lever is pulled down. They are often as powerful as clutch motors and sometimes more so. They only draw full power under full load. Thus, there is less heat and noise, as well as less electricity consumed (unless they are run all the time). Servo motors are much lighter than clutch motors with many having plastic bodies. Servo motors are usually easier to control, speedwise. But, there are some, usually the pushbutton type, that start spinning at 100, 200, or 300 rpm! These motors always start and stop with a jolt. I would avoid buying that type of servo motor if you need to sew very slowly. The better type of servo has a knob on a potentiometer (aka: POT), or multi-position switch, which sets the top speed. These motors mostly start at zero and pick up speed as you press further down on the floor pedal. Here is the type of servo motor I am currently using. Ultimately, no matter what type of motor you buy, the ratio between the motor and machine pulleys will determine how slow or fast the machine can sew. Upholsters usually want high speed over slowness, so they choose motors with a large pulley. It is common to see a 3.5" or 4" pulley on both the motor and handwheel. You probably won't want this if you are not sewing things that are measured in yards rather than inches. So, leather crafters usually opt for the smallest motor pulley they can find. In the case of the motor I use, this is a 50mm pulley, which is a special order for the dealers selling that type of motor. Most general purpose sewing machine dealers order the motors with a 70 or 75mm pulley, for speed. Smaller pulleys also increase the slow speed torque which helps penetrate leather or tough materials. Both clutch and many servo motors contain a cork brake that dead stops the motor when the foot pedal is backed all the way off. This is to prevent the machine from continuing to sew after you initiate a full stop. It takes a tiny amount of toe action to free this brake if you need to handwheel the machine. Motors without a brake (or with the brake disengaged on purpose) tend to will run on after you stop from a very fast stitching line unless you grab the wheel and stop it manually. Some of us take speed control a step further and add a speed reducer between the motor and machine. Their ratio may be 2:1 or 3:1, either of which really slow down the top speed and magnify the torque. RECAP Clutch motors are heavy, loud, draw a lot of electricity, produce a lot of heat and may be tricky to feather for slow speeds. Servo motors are much lighter, quieter, consume less power when not at full load and are generally easier to control (except the ones starting at a couple hundred rpm!). All motors are better at slow speeds if equipped with the smallest pulley (50mm/2" or less).

    Needle clamp for adler 30-1

    Then get some precision metal files. You are going to have to enlarge the horizontal slots in the clamp to make it fit the Adler needlebar. It requires very thin files.

    Needle clamp for adler 30-1

    I have an Adler 30-7 with a worn needle clamp (worn inside the needle hole) and when I tried installing a Singer needle clamp, it didn't fit right (sat on an angle). I'm sure that a Singer clamp can be filed to fit, but didn't go there for the time being. Curiously, the Adler needle clamp did fit on my Singer patcher! So, the ridges in the needle bar and clamp must be a little fatter on the Adler.

    29K8 new purchased

    That's a good looking machine and stand. It has all necessary parts. Accessories that are available include bobbins, bobbin cases (shuttles), threading rods, bobbin winder tires and presser feet. New leather belting and C clips are always available online. As for replacement parts, they are usually sold in the aftermarket and are made in China. Original Singer parts are out there, taken from donor machines that are stripped to the bare frame. You will pay about twice as much for genuine Singer parts than the Chinese knockoffs. I've seen genuine Singer 29k presser feet sell for over $30 compared to $12 for the knockoffs. The clone feet may not sit straight, or may be straight but off center, or perfect. Roll the dice.

    New to me Pfaff 1245 feeds backwards

    I think that bracket is to control the travel of your check spring.
  13. Try rotating the needle bar. It may be eccentric and positionable.

    Singer 133k or 29k

    Forget about the 29k for anything over about 6 or 7 mm. It is also best used with thin thread, like T70 or T90. It is a light duty patching machine used to darn rips in boots, or sew patches onto Biker vests. Also, the bobbins are either tiny or small, depending on the model. If you tell us the fuil model number we can tell you which size bobbin it takes. Example: 29-4, 29k71, 29k72, 29k172, etc. The ancient Singer 132 machines have a spring loaded jump foot that can simply slide on the top layer if it is too slick. If that happens you have to rely upon the feed dog to advance the leather. They are actually meant to sew buffing wheels and car wash cloths.
  15. This was an eight year old topic. There was no input about knee lever speed controllers because they aren't made for high power industrial servo motors. They draw much more current than the tiny motors used in domestic sewing machines. A typical industrial servo motor used in big sewing machines draws enough current to deliver 1/2 to 3/4 horsepower, which would burn out a domestic style controller in a tenth of a second. It is a case of apples and oranges. I am sure that some enterprising mechanically inclined individual may have hooked up some alternate means of controlling these 3/4 horsepower motors.
