You will probably have to post some means of letting members contact you about your wallet. Members can send private messages to each other, but not guests. Your options are to post an obfuscated email address, or phone number, or link to your website that has a contact form. I may be able to build your wallet once the details are firmed up. My website is: www.rw-leatherworks.com and there is a contact page with a contact form there.

I found your machine in 30 seconds using Google Search. Here are the search results. In a nutshell, this is a dual feed walking foot machine meant for upholstery or garment leather, or webbing, or vinyl, or heavy cloth. It is not designed for veg-tan leather, bridle leather, or any leather that memorizes markings. The feet and feed dog have aggressive teeth needed to transport the material.

Sometimes, the best and cheapest way to obtain spare parts, that are made of Unobtainium, is to buy another similar machine and strip the parts off of it.

The next closest Cowboy dealer I know of is in Toledo, Ohio. The only way to get a CB3200 cheaper is to buy one used.

Our regulations require that you show your asking price, shipping or pickup terms and location.

Bonded polyester thread has less stretch than bonded nylon and is UV resistant. It has marginally less breaking strength than the same size in nylon. It is primarily used in Bimini covers, sails, tarps, tents, awnings, motorcycle seats and outdoor furniture. It is at least 10% to 20% more expensive than bonded nylon. I keep a couple of spools of #92 black and white bonded polyester thread on hand for jobs that are regularly exposed to the sun. From what I recall, Cansew thread is top class stuff. Colors match across sizes and the bonding was very good when I last had some. They are mostly setup for the garment and upholstery trades and preferred to sell in quantities for less common sizes and colors. You may save money by setting up a wholesale account with them, then order a dozen spools at a time.

Can't you go there and pick it up?

I buy all of my motors from Toledo Industrial Sewing Machines. They are an advertiser here. If you want Boxing Day deals, your only recourse is to contact Techsew, in Montreal, Canada, where Boxing Day is still celebrated. They are also an advertiser with us. Gregg at Keystone Sewing stocks a lot of servo motors and is a contributor here.

Unless you have the adjuster's manual, or have somebody else who knows what they are doing, I would lower the presser bar to avoid contact with the needle bar. The only effect this will have is to reduce the clearance under the feet by about 1/16 of an inch, or less. Lowering the needle bar may throw off the hook timing, leading you down a slippery slope that will result in more headaches than you have now. Later on, you may learn how to check the needle to hook timing and the proper way to adjust it. Then you can raise the foot to regain any lost clearance. Just my 2 cents worth.

If the bottom of the needle bar hits the top of the feet, you can either raise the needle bar a smidgen, tweaking the hook timing to match, or lower the presser foot position to avoid impact. There will be one set of co-adjustments that will yield the maximum foot lift without hitting the needle bar, along with effective hook timing in forward and reverse at all factory standard stitch lengths. The higher the lift and longer the stitches, the more critical all adjustments become.

Many sewers have pondered the mysteries of the bobbin system, hoping to discover a way to use a spool of thread instead of a wound bobbin inside a case. The best they have come up with is the chainstitch mechanism. This system only uses one spool of thread which is on the top. Aside from the appearance on the underside, the problem with a chainstitch is that unless it is waxed, or sewn over, it can totally unravel by pulling on the thread in just the right direction. Garments sewn with a chainstich are usually sewn over at the beginning and end to keep the thread from unraveling. An example of a waxed chainstitch would be a dogleg style leather rifle case. They are usually sewn on a Puritan chainstitch machine with linen thread run through liquid beeswax in a huge wax pot on top of the machine. The chain is protected by the material lining inside the case. The same chainstitch system is used in the McKay sole stitchers with a rotating horn. With these the chain is covered by the slip-in insole, as well as wax on the thread.

Every now and then I experiment and switch my long body walking foot machine to use System 190 needles. I find that any gain in needle stroke is virtually offset by having to lower the presser foot to clear the bottom of the needle bar's thread guide. Unless a machine was designed to use System 190 needles, you will need to file or grind something out to get the full benefit of the longer needles. The hook timing and check spring throw also needs changed.

I saw the starting top thread being held back outside the inner foot's hole. Try feeding the top thread through the hole in the inside foot before you sew. It may solve your mystery.

You could change the motor pulley to a 2" (50mm) pulley and get a shorter v-belt to keep the existing motor position in roughly the same place. Your motir uses a type 3L (3/8") v-belt. The size in inches will be marked on the outside of the belt. If you have a 4" pulley now and replace it with a 2" pulley, buy a 2" shorter belt. The last servo motor I bought was a Family Sew FS-550s, which cost about $150, shipped. The dealer changed the factory pulley to a smaller 2" part at no charge. I already had extra v-belts so that saved me about $7.00 or so.

Are you saying that even though you hold back both threads, the top thread is giving up at the needle? First, make sure you are using the correct needle system and size and that it is inserted with the thread channel on the left side and scarf on the right. If the machine does sew at all that translates into the top thread is breaking (possibly from a burr). If you can't get any stitches at all, the timing has gone out (likely), or a safety clutch has popped. Inspect the hook to see if there is a jagged edge at or near the pointed end. You can watch the timing as you hand wheel the machine. The needle should go down to BDC then begin to ascend. The tip of the hook should intersect the needle about 1/8 inch above the eye as it ascends. That's usually where the best loop forms on the right side of the needle. If the hook arrives after the eye of the needle has passed it, the timing is retarded. If it arrives below the hook, it is advanced. The needle timing can be thrown out by impacts against metal or very hard material. Some machines have one screw holding the needle bar in position. A solid impact, or series of impacts can cause the bar to slip up enough to de-time the machine. A thread jam in the shuttle usually cause the timing to change. Some machines have a safety clutch that disengages the shuttle drive to protect it. If the clutch pops, you need clear out thread remnants in the shuttle and bobbin race, then hold down a button on the bed while turning the hand wheel, usually backwards, until it snaps back in the drive position.

If this was April 1, this post would make sense.

I had a plastic body Janome, like the DC2012, and it blew up trying to sew a belt. As for the aluminum body 221, it may handle 4 ounces of soft leather using #69 bonded nylon thread and a #18 needle. But, if the gutless motor starts grinding or smelling bad, stop immediately! These are both meant for sewing broadcloth only. Look for a used or rebuilt walking foot, upholstery grade machine with a big motor and 20" x 48" steel legs table.

What make and model is the sewing machine that these parts go onto?

I am confident that they have representatives and sales people capable of answering your questions. For instance, Junwu Jiang is a Cowboysew/Hightex rep on Facebook. He is multi-lingual and lives in China.

Have you contacted Cowboysew/Hightex Sewing company yet (links to Chinese language version)? They are located in Zhejiang, China. Many of us in the USA, UK, Canada and Australia use their machines on a daily basis.

Reverse sewing can only be achieved by having a mechanical reverse mechanism built in, or by turning the work around 360 degrees and sewing back through the previous stitch holes.

Assuming this is an industrial leather sewing machine and not a domestic garment machine, could you please provide more details about the machine's make and model and/or the type of motor you are installing? Why can't you take a picture and upload it to our forum? If your camera takes photos that are too large to upload, reduce the resolution or use photo resizing software to make your images much smaller. One such program is FastStone Photo Resizer.

A buck three eighty nine is too much! ;-)

Please call the dealer you bought it from. They understand the internals and will figure out what needs to be done.

Singer Manufacturing Company was a World wide corporation with plants all over the place. Simanco was one of their trade names. It was not limited to any one factory, or country. During war times they tooled up for non-sewing operations for the military. They even produced 1911 semi-autos in the USA during WWII, as well as bomber optical sights.
