Could the needle be getting hot and making the thread stick to it instead of being caught by the bobbin hook?

That sounds about right.

Does it have a servo motor, or the clutch type? I have sold several 111w155's for $300.00 with the clutch motor, I put them in my table that has a servo motor and let the buyer try them out. They always want to know where to get the Consew motors, as they are easier to use at low speed.

Keep looking. I found a 111w154 head on Craigslist for $80.00, offered 40 and got it, seller also gave me a nice servo motor to go with it. I cleaned it lubed it up, checked the timing and put it in a table. Sews like a champ....

He just wanted something to keep the roos and koalas from chewing the bags off.

Have you checked the thread guides to see if any of them have excessive wear where the thread has run thru them? I have a 95-10 that shredded the thread, made all new guides from stainless steel rod and it cured that problem.

I thought he might be able to use one if he was close by.

I have two tables that 111w155 machines came from. i am in North Carolina.

Where are you located?

I can make the bottom shaft, If I still had access to a lathe I could make the upper also.

Does that include shipping?

How much for them?

Look on Craigslist and similar sites for free leather furniture, A leather sofa has many square yards of goods.

I need both the upper and lower shafts for a 111 w 155, as I caused my newest machine to fall from my truck and broke them. Duh. I have looked,to no avail. Any help is appreciated.

First servo motor (500 watt) I bought lasted a month. It just would not run, have no idea what happened. The next one was a Consew 750 watt unit, it is bigger and has worked flawlessly.

It is not cycling properly, the pump does not change pitch as it is under no load, the signal is not getting to the relay that controls the stroke. if the pump was under load it could be heard as in the hydronic press video. First thing to do is change the oil.

Does it have an inline filter? If so, remove the line going into the filter and pump the oil into a container. The gear pump will pick up and push most of the oil out of the system. Then refill the reservoir and test the system. If no filter, just remove the line that feeds the hydraulic cylinder and let it pump into a container. Same operation, different method. NOTE- the oil will come out with great force, be careful.

I am near Gastonia, but someone is coming to look at the machine Monday. This is not a large bobbin machine. What is wrong with your 154? What parts do you need?

I have one in North Carolina, $300.00 plus shipping. Tables can be found many places, of course you need a servo motor- $125.00 Consew models, from amazon. These heads weigh about 60 pounds, you can calculate shipping, I will crate it.

That does not need to be adjusted unless you go from a large diameter thread to a very small one. Usually. Top thread tension seems to regulate the bobbin thread tension good enough.

Mine looks like crap now. Too bad I don't have a machine shop.

post an image of the area of the hook, where the thread is shown and discussed in the video above. Is it a Simanco hook? just curious.tyvm quote--(I was hoping someone could help me with adjusting the presser foot knee lift. Whenever I do it, the rod on the machine seems to want to twist, and then all of a sudden it "lets go", and makes a spring type noise. From the videos I've watched, the action is suppose to be smooth. Also, could someone explain how to adjust the spring that is on the rod itself with the set screw? Not sure where to set it exactly.) The end of the lifting rod under the machine needs a smooth rounded surface, like a small wheel, or in my case a small heim joint that I repurposed. I just slid the end over the lifting rod, with a thin piece of foam rubber wrapped around the rod to prevent it from falling off. You could thread the rod if it was the right size, mine was not. The round surface will provide a better smoother action where it touches the metal pad when you use the knee lift.

Wat? Kinda lost here...…..

I tried to keep it evenly worked, so that the original shape was kept. Some 1600-2500 grit sand paper is needed to polish it also. The NEW generic hook was as pointed as a needle, tested by poking the web between thumb and first finger. A GOOD magnifying glass is really handy. A strong one, like from the eyepiece of a pair of binoculars. Is your hook a Simanco, or generic? Sharpening won't help too much if it's not Simanco., imho.

Today I was playing with the machine I am keeping and slowed down to turn a kinda sharp corner and it skipped a stitch , then another. Looked at the hook and it was NOT a Singer hook. Good time for an experiment with hooks, so I used a fine stone on the point of the other used hook which is a Singer, to make it nice and sharp pointed, as it was just slightly dull.( It would not make a pin prick feeling on the meaty part of my hand, that's the only gauge I have) Replaced it for the one in the machine which has no brand name on it, checked the timing, it had not changed so I turned it thru a few times by hand then let er rip. I tried to make it skip stitches but it would not. Go fast then slow and turn or just slow or stop. It did not skip any more. The part of the hook where the thread slips off as seen in the video above, on a Singer hook, is just a little bit longer than on the no name hooks. That small difference in the hook shape seems to me as what causes the skipped stiches.
