If you can rotate the hook to get the tab on the basket facing you, you might try prying the basket up with a wooden spoon or flat stick. The thread must have really gotten wound around the hook multiple times. Did you know about holding back the starting threads, especially the top thread when you start sewing? Vertical hook machines all seem to suffer from thread around the bobbin case if the starting threads are left loose.

Try pulling on the thread while jiggling the wheel. You may be able to free it enough to pull the thread out. When that doesn't clear the thread you'll have to remove the bobbin basket. To do this, unscrew the three tiny screws and remove the curved bracket holding the bobbin basket in the hook housing. Use a small blade magnetic or magnetized screw driver with a fat handle to loosen them. Place the screws on a magnet so they don't get lost! Oil the hook and bobbin basket race after clearing the jam. Don't forget to reinstall the throat plate and align the bobbin basket tab in the indentation in the plate.

I too use Leather Tape to hold seams and patches in place. Know that if you sew through the tape itself, titanium coated needles work better than plain steel at resisting gumming up. I also keep a dauber handy and dip it into a 4 ounce jar of Goof Off to clean adhesive off the eye of the needle when it gums up.

You should back off the pressure screw on top of the left side of the head, over the presser bar. This screw pushes down on a coil spring that pushes on the outside foot. There may also be a second, smaller screw adjuster over the inside foot that can be backed off. Perhaps your brushless digital motor is dependent on the needle positioner due to the way it was set up at the factory. If you want to change motors, look for an analog brush motor with a speed limiter knob, like the one on this page.

The Cotton Yarn numbers of #30 ~ #8 roughly correspond to bonded Tex sizes 70 through 210. Due to the totally different materials used, the sizes don't translate as accurately as measurements for cotton, or polyester, or rayon thread. There is a thread size comparison chart that includes cotton yarn equivalents on A&E Thread. There is no cotton yarn number comparison within the bonded nylon and bonded polyester groups. My best guess it that your T135 thread would be about the same diameter as #12/3 cotton. But, cotton is much lighter than nylon.

Since I changed over to the Aussie narrow feed dog and throat plate I've left them in. We sew holsters with them just fine using #277 thread. This set should have been a factory option. The real advantage is that narrow straps don't get pushed into the slot like on the standard plate and soft material isn't pushed inside the feed dog as easily. I think that we could use another feed dog that fits in the narrow throat plate, but with a smaller hole that clears a #23 needle, maximum. The other day I needed to use my raised holster plate. The narrow feed dog cleared the bottom with ease. No need to lower it.

I have a U shaped table for my Techsew 2700. It is raised up as high as it will go so I can sit on a barstool when I use it. Otherwise, it would work fine if lowered. My machine also has a foot pedal to lift the feet.I use my right foot to lift and my left foot to control the speed. I do this on all of my machines, even the ones with a knee lever (right knee->right).

I cannot speak for the other member. But, I did repair one turnout suit last year and I did it on a standard duty cylinder arm machine and on a long arm, big bobbin shoe patcher, using a couple different sizes and colors of Nomex thread. There is no need for a machine heavier than a normal walking foot machine unless you plan to "make" this gear. I never encountered a seam that wouldn't fit under the raised foot or feet. The material was never tougher than my machines could handle. The thickest part was the new cuffs on the bottom of the legs. These were easily sewn around the snout of a Techsew 2700 cylinder arm walking foot machine using T90 Nomex with a #19 leather point needle. When I sewed through cloth or Reflexite, I used a round point needle. This said, you could sew/repair firesuits on a Cowboy CB3200, until you get deep inside a leg or sleeve. That's when you'll need a long arm heavy patcher. I use an Adler 30-7. The next model up is a 30-70, or a Claes. These are very expensive machines that sew over 3/8 inch thickness and can manage #138 (T135) thread. The largest Nomex I found was T105, which is well within the limits. If you do offer your services to repair turnout gear on a repeat basis, obtain liability insurance in case a repair fails and you get sued. Also, be prepared to send invoices and wait for checks to be issued.

Good luck getting a reply. This topic is 3 years old. But, ya never know!

My pleasure!

Here is a search page showing results for sewing piping onto leather seat cushions. There are photos and YouTube videos showing how this is done. Piping can be made or purchased. It does usually require a special presser foot set that rides on top of the piped material and positions the needle on the right edge of the pipe or welt. These piping feet are sold online in various diameters, from 1/8" up to 5/8". The most common size in seat upholstery is either 3/16" or 1/4".

Eleven years ago I bought a used/rebuilt long arm Singer walking foot machine. It is used on a weekly basis to sew patches onto the backs of biker's vests and jackets. The extra clearance lets us keep the back flat and just fold up the fronts as we twist and turn. The same work on our standard length walking foot machines is tedious. There just isn't enough clearance for large or bulky items to be rolled up out of the way.

You might need piping to tighten up the seams and hide the thread and holes.

I might also be interested in some thinner shims. I occasionally use my 4500 to sew with thin thread and needles when that is the most useful machine for the job. The shims could go hand in hand with your narrow feeder and throat plate.

I know this is counterintuitive, but there are times when a round point needle produces a cleaner corner appearance than a typical leather point. You could do an experiment in scrap leather using a 135x17 needle. I would also try a Diamond or Triangle point needle. The appearance is close to a round point, but produces a three or four sided hole. The thread will visibly sit on top using either of these needle types, as opposed to an S point which looks submerged.

Some people have success when they push soft plastic tubing over the feet. Carb tubing might fit, but might have too much wall thickness. You will lose some usable sewing thickness if you slip or heat shrink tubing onto the toes.. If this doesn't work, consider getting a different sewing machine for those projects. I recommend a compound feed walking foot machine in either cylinder arm, or flat bed, or post bed configuration. These can be equipped with completely smooth feet.

You can read or download a user's manual here. If you are able to learn to "feather the clutch," you can keep the clutch motor. Otherwise, buy a servo motor with a dial speed limiter like this one. No! This is a tailoring machine, with bottom feed only and a flat foot, meant to sew cloth. Some members use them to sew light weight chap leather or other projects using soft leather. It isn't designed to use heavy thread and you'll have to help the foot over changes in layers. I use and recommend a walking foot machine for sewing vinyl and canvas, as well as denim and upholstery leather. The belt may be loose due to the motor being purposely adjusted to let it slip. Try tightening the belt by lowering the motor position via the threaded rod on the front. If you have a nearby hardware store, ask them if the stock "Type 3L" v-belts. Bring in the old belt as a reference for a same size replacement. You can find replacement parts, needles, bobbins, thread, oil and different presser feet and bolt-on guides and accessories from most industrial sewing machine dealers, or on Ebay.

@medion One thing that hasn't been mentioned is the needle system you are using. Are you using System 190 or 135x16/17? Whichever you were using, have you tried changing the needle bar height and using the other system? I sometimes raise the needle bar on one of my specially modified machines to use system 190 needles and notice some oddities vs system 135x. I attribute some oddities to the longer needles flexing. One more thought that flashed across my mind is the alignment of the needle's eye. Have you tried altering the rotational alignment slightly? Perhaps the angle that the thread passes through the eye affects the tension on corners as you rotate the work clockwise. I wonder if a slight clockwise rotation of the needle would help?

The problem could be caused by twisty thread (top and/or bobbin), or a change in the density of the leather as you round the corner, or the glue/tape you baste them with, or the needle point shape, or the foot pressure, or by the setting of the check spring. Obviously, the tension has changed after turning that corner. Try reversing the direction of the bobbin and adjust the tension to balance the knots. Run a little higher overall tension to make it easier to position the knots. Try to watch the leather as you round the corner to see if it lifts with the needle. More foot pressure would subdue that problem. Try a different needle with a different point. A diamond, or triangle point may help. Use titanium coated needles and keep a dauber and Goof Off handy if you sew through leather tape or heavy cement.

That might be a 29k58, not a d58. This is a shoe and boot patcher (uppers only). I use my patchers to actually sew patches onto biker's vests. They are also good for repairing shoe straps, purse and bag strap tabs and replacing zippers in purses. The foot does all the work and rotates 360 degrees. There is no bottom feed and the foot leaves tooth marks on veg-tan leather. The bobbins are tiny and hold no more than about 9.5 yards of #69 bonded thread. The maximum thickness it can sew and move is just over 1/4 inch. The longest stitch length is 5/inch at about 6-7 ounces, if it is in pristine mechanical condition. Most patchers coming out of shoe repair shops are well worn and may only get 8 or 10 to the inch. The most frequently used needle size is #18 (Metric 110). The needle "system" is either 29x3, 29x4, 135x16, or 135x17. Because the bobbins are so small, there's no sense loading them with anything bigger than #92 bonded thread. This calls for a #19 (Metric 120) needle.

There are a couple of machines that can handle up to 36 ounces. The primary ones I think of are the Cowboy cb3500 and cb4500, the Cobra Class 3 and Class 4 and the Techsew 5100. There is also the option of a manually operated stitcher like the Cowboy Outlaw.

The Cowboy Outlaw will do what you ask for and is within your budget. It has a deeper throat than the Boss. But, if business picks up, your arm may get tired after a while. ;-)
