This 205 variant has been discussed on Leatherworker.net and elsewhere in the past. Here are some links to those conversations and a manual. https://leatherworker.net/forum/topic/19014-adler-205-8-qustions/ User manual from Adler Considering that it has bottom feed only and uses system 214 needles (same as a Singer 45k), I doubt it can sew anywhere near an inch. It's more like 1/2 to 5/8 inch.

I only use bonded nylon or bonded polyester spools of thread in my lockstitch machines. The only lube on thread should be silicon thread lubricant.The maximum your Consew 227 can handle is #138, with a #23 (aka 160) needle. If the seams are taped or glued, use titanium coated needles. Keep a small can of Goof Off and a dauber handy to clean the adhesive off the needle.

Wrestling match- which machine is Best
Wizcrafts replied to jrprottas's topic in Leather Sewing Machines
There is one I know of: Juki LU-1508NH that has a longer needle stroke, takes System 190 needles and can be setup to sew 1/2 inch with up to #207 thread, using a #24 needle. The next step up is the Juki TSC-441 that sews at least 3/4 inch with up to #415 thread and uses System 794 needles. -
The #26 is the old Singer size. The 230 is the metric designation. Some of us think in Singer US sizes while others think in millimeters. The bottom line is that a #26/230 needle is the proper size for #346 thread, top and bottom, and it pokes a really big hole. My largest needles are #27. Some giant harness stitchers and sole stitchers have humongous holes in the throat plate or feed dog that allow for a #30 needle. I once had a needle and awl set for a Union Lockstitch machine that resembled roofing nails, which covered #554 bonded nylon thread.

Followup info. Your domestic sewing machine uses "low shank" (short) feet. Industrial straight stitch machines use high shank (tall) feet. Never shall the twain meet.

As a stopgap measure, buy either a Teflon or roller equipped presser foot (for domestic sewing machines) that lets leather glide under it rather than be dragged. To sew with #69 bonded thread you need either #16 or #18 needles. If you are sewing cloth or webbing, or vinyl, use standard round point needles. When you sew leather change to leather points. The roller foot may require an adapter to mate it to your domestic machine presser bar. This, combined with the thick foot, will reduce the clearance under the foot to about 1/8 inch. Teflon presser feet are simpler to use, but are easily damaged if they land on top of the feed dog teeth. It's best to buy a bunch of them at one time so you can swap them out as you forget about avoiding the teeth (ask how I know). You may also be able to improve the feeding of leather by spraying the top of the seams with silicon as you sew. Keep the bobbin winder knob as tight as possible on the flywheel. The impact of sewing leather tends to cause it to loosen and may allow the wheel to spin and not drive the machine. Finally, try to buy titanium needles for sewing leather, or any other textile that is secured by basting tape.

The Singer 15 class machines are domestic use, cloth garment sewing machines with bottom feed only. They have light weight take-up and tension parts and are not up to snuff for sewing leather of much thickness over a few ounces of garment or thin chap leather. Leather that is sticky on top doesn't feed very well on this type of machine. You are best to dedicate that machine to sewing cloth and look for a used industrial walking foot machine for sewing leather, vinyl and webbing. A good starter machine would be a Singer 111w155, or a Juki LU-562, or a Consew 206RB-1 through -5. The criteria to watch for is triple feed, where the needle, inside foot and feed dog move in concert as the outside foot alternates up and down.

Wrestling match- which machine is Best
Wizcrafts replied to jrprottas's topic in Leather Sewing Machines
This describes the Cowboy CB3200. You would want to order it with a range of needles and thread covering thread sizes #92 through 277. Then, consider a flat slotted throat plate for lighter weight projects and smaller thread and needles. Get lots of bobbins and preload them with various sizes of thread. Buy thread spools in pairs of each color so you can wind a fresh bobbin as you sew. -
Union Lockstitch needle plate #615
Wizcrafts replied to DavidMillsSaddlery's topic in Leather Sewing Machines
I might could use a needle clamping screw that goes on the needle bar, among other parts. Do you have that screw in your spare parts? It is square headed. -
System 134 sounds right for that Pfaff. Avoid 134-35 as they are too long. You want System 134 Leather Point or Diamond/Tri Point. The needle bar can be raised to accommodate longer needles, but why do that?
-
I have two machines that drop into the same table. The knee lever works for the walking foot machine but not the 31-15. However, it can be altered to lift the foot in the 31 class machine. Better yet, get a table with a foot lift floor pedal that can pull down on the lift mechanisms with a long chain. Just make sure you buy manual oiled machines that don't need an oil filled pan. Then buy a straight stitch and a walking foot that have 7" x 17" beds. The tilt pin holes can be modified so both machines can tilt back in the table clamps.

I see from your profile that you are into shoe making. A lot of shoe and boot makers use 31-15 machines that are converted into roller foot machines to sew decorative patterns into the uppers.This class of machine can sew very tiny stitches with small thread and needles. You can buy bonded nylon thread as small as #33 and lay down an intricate pattern at 24 to 32 stitches per inch, using a #9 needle. Also available is #46 bonded thread which can be sewn with a #12 or #14 needle. You won't get the same short stitches as with the smaller needle, but it will still sew a nice pattern at about 16 per inch.

I have the US version of that machine: the 31-15. Yours is British, made in Scotland. It is essentially the same machine as mine. The 31(- or k) 15 uses Class 15 bobbins and is a tailoring machine. The foot lifts to about 1/4 to 5/16 inch. But, with higher foot lift there is a risk of activating the tension release pin prematurely. That would cause a total loss of top tension. You are best not sewing more than 1/4 inch on that machine. The feed is drop feed only, via interchangeable feed dogs. For leather you'll want to purchase an aggressive feed dog and matching throat plate. If the leather drags under the foot you may need either a Teflon or roller foot. With smooth feed it should get 5 stitches per inch. If the standard foot grabs the leather you'll get shorter stitches. The maximum safe thread size is #69 bonded nylon, with a #18 needle. You may possibly be able to get it to sew with #92 bonded thread using a #19 or #20 needle. However, the beehive tension spring on this machine is rather feeble (meant for thin cotton thread) and may need to be replaced with a walking foot tension spring for nylon thread. Your 8 ounce soft leather seams should be well within its capacity. Three layers would be pushing it, especially since it has bottom feed only. If you try sewing dense leather you'll likely cause the needle bar to move up from the impacts. That will throw out the timing. Despite its appearance, this is a light duty sewing machine. FWIIW, I only use my 31-15 for cloth garments and jacket linings and sometimes for thin pigskin wallet interiors. I use walking foot machines (and patchers) for everything else.

Union Lockstitch needle plate #615
Wizcrafts replied to DavidMillsSaddlery's topic in Leather Sewing Machines
ULS made various shapes of slide-on throat plates. I used to have custom throat plates made when I had those machines. Yours is obviously a raised and tapered plate, possibly for footwear. The holes for the edge guide are a bonus because the shorty plate doesn't have slots to mount a swing-away edge guide. You should request a copy of the user's threading and parts manual from Campbell-Randall. Parts are still available, but are not cheap. -
Only used and very old industrial sewing machines sell for the $400 price point. New, they sell for $1000 and up. Tandy stores should have a portable walking foot machine made by Sailrite, that is able to sew 1/4 inch of leather with #92 (15 pound test) bonded nylon thread. Consew makes a great low cost walking foot machine as the Consew P1206RB-1. It is a quality machine that will do what you want with up to #138 bonded nylon thread (22 pound test), into 3/8 inch of medium temper leather. Janome doesn't make industrial leather sewing machines. The model 3000 is a plastic body domestic (household) cloth garment sewing machine.

Considering the age of that long-obsolete model and what has been done to modify it, I'd say it is what it is. I doubt you will be able to restore it to its original configuration. Of course, I've been wrong before.

These are probably NOT the type of sewing machine you need to sew very thin or soft leather and other fabrics. It really boils down to the firmness of the leather or other materials. The whole problem is that compound feed walking foot machines have a small inside foot that pushes down hard directly over a large, often oblong hole or slot in the feed dog. That dog moves inside a large rectangular cutout that can be a trap for thin, soft material. You would be better served by either a straight stitch machine or a dual feed, fixed needle machine. The only possible drawback is that dual (top/bottom) feed machines have teeth on the top and bottom. They will mark the leather on both sides. Moving along, straight stitch drop feed machines usually have static position needles with a single fixed position presser foot. The needle goes through a small hole in the throat plate. They are just like domestic sewing machines, but much more robust and mounted on 20 x 48 inch tables with big motors underneath. You can get a roller foot conversion kit for most Singer straight stitch and their clones. I had a 96k40 that had a roller foot conversion and used it to sew leather vests that were too soft for my walking foot machines. I now have a Singer 31-15 that handles flat work. The roller rides on the left edge of the needle giving great visibility. It revolves over leather instead of dragging it. When you aren't sewing leather, a standard flat foot can be installed. They comes in all kinds of styles, like narrow zipper, piping, edge guides, wide toes, left toe, right toe, dohseedoh. Not gonna happen on a light duty straight stitch machine. Maybe #92, but more likely #69 bonded nylon and 1/4 to 5/16 inch. Walking foot machines can handle #138 thread. A few can tension #207 if specifically set up for it. Most do sew 3/8 inch, but that is usually the upper limit. Some newer models can sew 7/16" with #207. But, they will be rough on 2 or 3 ounces and probably eat it.

Juki LU-563 vs Consew 146rb-1 vs Consew 226
Wizcrafts replied to DylanW's topic in Leather Sewing Machines
Depending on their conditions, I'd look at the Juki LU-563 or Consew 146rb-1 before the Consew 226. The 226 has a smaller bobbin. The significant differences between the first two is that the Juki has triple feed, straight stitch and a drop in extra large bobbin, whereas the Consew 146 has top and bottom feed only, a slightly smaller M bobbin and wide zig-zag. The Juki uses Singer 111w155 style feet which are available in a myriad of configurations. There would be fewer presser foot options for the Consew 146 compared to the Juki. Also, the Juki 563 may take heavier thread than the Consew. -
Does anybody have some spare System 332 LLG #24 needles?
Wizcrafts replied to Wizcrafts's topic in Leather Sewing Machines
If you do buy some 100 packs in different sizes, let us know. I can use more leather 332LLG in leather points in various sizes. There are quite a few owners of Adler 30-7 and 30-70 machines. I'm sure we can help offset your cost. -
The 241-12 is definitely not for use in leather sewing of any form fashion of kind, without huge modifications. It is a high speed, drop feed only, production sewing machine that only takes thin thread. They are not meant to be run slow.

Trading, buying, selling: need advice on my next machine
Wizcrafts replied to ensitmike's topic in Leather Sewing Machines
As I said, the 2700 is a light leather sewing machine. The CB341 (cloned from Juki 341) is much beefier for similar money. It uses a larger M style bobbin and can tension up to #207 thread, which the 2700 cannot handle. If you can't afford one of the new qualified cylinder arm machines, go used! We have a marketplace section of the forum where people can sell used sewing machines, among other items. Oftentimes, these machines are in very good condition and are being sold because the owners bought newer, more expensive machines to replace them, or have just gone out of business. That's how I acquired my Techsew 2700. -
Campbell Randall awl/needle/thread sizing
Wizcrafts replied to gordond's topic in Leather Sewing Machines
Call Campbell Randal Company for their advice on needle and awl vs thread combinations. They will ask what thickness and density you are sewing and what thread you will be using. I have owned 2 Union Lockstitch machines and always used a full size larger awl than needle. I used to match the thread to the needle by pulling various needle sizes along the top thread until it got tight. If the thread was tightly bonded and lubed I would use a tight fitting needle. If the thread was loosely bonded, or linen with any kind of wax, I chose a larger needle so the thread wouldn't stick inside the barb at pick-off time. The awl has to poke a big enough hole for the lockstitch knots to pull up. Experiment! -
The Singer 29k2 was probably built sometime during the late 1890s through very early 1900s. Look up the serial number on ismacs, as linked to by Jimi. The original body color is black.

Trading, buying, selling: need advice on my next machine
Wizcrafts replied to ensitmike's topic in Leather Sewing Machines
If you intend to open a shop that does leather repairs, you will regret losing the patcher. If you just build things at home, not so much. It is, after all, about 100 years old. I have a Techsew 2700 and it is a good walking foot machine. It uses standard Singer G size bobbins and takes a plethora of Singer 111w155 feet. The machine can handle bonded thread sizes 46 through 138. Note that the machine pulley isn't very large and it tends to spin really fast. I had to install a 2:1 speed reducer on mine after installing a servo motor that has a 2" pulley.
