SOURCE: machine jamming

Hi! It's possible that the thread is too heavy, but there are other possibilities also. What size needle are you using? Is it a leather/vinyl needle? Also, it could be a tension problem, so try adjusting that on a scrap of the vinyl.

I found this bit about marine threads (http://www.seattlefabrics.com/thread.html). There are different sizes/weights of marine threads and it could be that you need to find a different marine thread.

Hope this helps!

Thread shred. Pfaff 463. Using 120/19 new needle. And Sunguard Anti-wick UVR bonded polyester thread for marine canvas. Why is my thread shredding?


From my past sewing experience (not an industrial machine), the thread will shred if the needle/thread/fabric are incompatible. Could be the canvas is too coarse and is wearing on the thread like sandpaper. Remember, the thread/needle will penetrate over 10 times before that section of thread actually forms a stitch, so that's a lot of friction going on. In regular sewing, a top-stitch needle has a larger scarf which acts to protect the thread, however, not sure that is a choice for your machine.

Is pfaff hobbymatic a heavy duty machine?


The term "heavy duty" sewing machine is thrown about loosely lately. There are new machines (including Pfaff, Singer, etc) for sale advertised as "heavy duty," but I would be hesitant to stitch denim jean hems on them. The Pfaff 807, which appears to be an older mechanical, is probably more "heavy duty" than some newer machines on the market. However, "heavy duty" does not mean that you can sew big canvas sailcloth or heavy upholstery projects. A domestic machine (which the Pfaff 807 is) is really meant for general domestic sewing. If you want to sew "heavy duty" fabric, then look to an industrial machine. Remember that frequent sewing of heavy fabric takes a toll on a domestic machine, ie the motor, needlebar, other working parts, thus hastening the demise of your machine and the more frequent need for service & repair.

I am trying to sew a boat canvas top with sunbrella canvas. my top stitch is beautiful but the bottom stitch is loose and messy. Is this just a tension adjustment and if so what should I be adjusting?


Try adjusting the top tension dial to tighten up the loose stitching on the underside. Generally if you have loose threads underneath, its the top tension and visa versa.

However, if you are using a thread heavier than normal sewing thread through the needle and bobbin (which you probably need for this canvas) then the machine may struggle. I've sewed vinyl seat covers and gave up with my domestic machine and purchased a second hand industrial Singer machine 20U to cope with this heavier weight textile. Generally for anything heavier than upholstery fabric a domestic machine may not be strong enough.

Can the consew 339rb-1 be used only with 1 needle?


this is the specifications for the 339rb-3. they sould be close to yours, if you can put two seperate needles in and the machine hase one hook and bobbin case then I would say you can use one needle, if you have two hooks and bobbins, I would say no, you may want to thread with one and just hand turn for a few stiches to sew hoe it reacts, leave the bobbin door open so you can watch the hook.

Tension


I answered this a couple days ago but don't know if it went through. I can sew through 6 or more layers of denim with my 226, no problems at all. In my 30 years in the upholstery business I never had a problem sewing leather, vinyl, canvas or multi-layers of fabric. The 226 Consew, the 111W and 211w Singers I had presented zero problems with heavy fabrics - and I don't consider vinyl "heavy".

You need to first of all check threading. If the machine's threaded wrong you're break thread. Also you need to oil under the bobbin case and the bobbin hook and the rest of the parts as well.
Then, loosen thread tension on top by turning the knurled knob that's on the spring that's holding the tension discs. Also loosen bottom tension on the bobbin case by turning the small, left-most screw on the outside of the bobbin case counter-clockwise. Do both with the presser foot down. Pull the thread(s) out and feel the tension. You should be able to pull the threads out with some little effort. Tighten both a little at a time until you get some tension. Run a couple seams and check where the threads meet in the fabric. They should meet in the center. Also check stitch length. If you're using 92 thread (is should be left twist), you should run the machine at about 6 - 7 stitches/inch. I'm running my machine at 5 - 5 1/2 with #69 nylon bonded, and 6 - 6 1/2 with #11 mono.
One more thing; if tension's too loose at the bobbin or top, the machine will jam in the bobbin and thread will break.
Go to www.consew.com and download a pdf owner's manual for free. You need to click on the 224. That machine, the 225 and 226 are the same.

Question==>JUKI dnu 1541 or ddl 8300n


Might I be so bold as to disagree with Allmakes.
Why would a manufacturer build different models of industrial. They are designed for differnt jobs. The 8300 is a high speed garment machine, the 1541 is a compund feed upholstery machine. The motor is the same HP and does not affect the ability to sew heavy. The garment machine will sew garment weight leather just fine but you will have problems getting the fabric to feed properly particularly over seams. The other issure you may find with a garment machine is it's ability to handle heavier threads. I suggest that the 1541 would be a better choice for making bags and purses.
