Do These Parts Do What I Assume?

[Evo160K]

Cleanview,

Take what I'm saying with a grain of salt, because I don't sew much. If you're trying to relieve the downward pressure on the foot by following those particular printed instruction, I don't believe that's how to do it. Others will know. I believe there's a different adjustment for pressure on the foot. You'll be well informed once you get past this episode.

Put that walking foot adjustment in the center of the slot and leave it alone for now. Tighten your tensions back to where they were . The presser foot pressure is adjusted on the very top of the machine. It is the black knurled nut that is around the shaft sticking up on the top left hand end, counter clockwise will lower the pressure.

Look at the positive side of all this.....by the time you're done, you'll know this machine inside and out.

[cleanview]

oh, A glass is half full kind of guy.....I am going to know this machine better than my wife before its over, well there both easy to mis understand anyways.

I do know where the pressure to the foot is adjusted.....it was that it was referred to as the center of the foot, and when I looked at it the center of the foot it was the walking foot. and down that dark path I went......it was a very dark path

I have put it in the center ....heck I had that thing in every imaginable position ....then I remembered all those pics I took of it in this thread and think I have it back where it goes........just something aint write......keep getting loose threads.

Well i woke up early to go hand stitch, but instead I will get back to the drawing board

This mornings sewing after adjusting

Still not sucking the knot in far enough.

Thoughts

Longs thread, (forum) really appreciate it

That looks like a tight hole, at a glance.

Always always always start with the simplest 'fix'. Not 'sucking the knot' enough means...

1.) Hole too small for the thread size

2.) Too much bobbin tension

3.) Insufficient top thread tension

First check the obvious...

277 thread? Then we should have a 24 or 25 needle. Hole size, check. (For 277/207 combo I like the 24 needle, for 277/277, I use the 25).

With a tension issue, don't auto assume you need to start compressing springs and moving dials. Is there something in the path of the thread binding or dragging (creating tension NOT related to a setting). Is the thread coming off the spool smoothly (this seems obvious, but really). Pull the bobbin thread with a thumb and finger.. can you pull thread smoothly? Is the bobbin in the machine so that thread spools off the bobbin the right direction? This seems like no big issue, but it really can make a difference.

Your bottom stitches look fairly consistent. They're consistently too low, but consistent. Point is, if there was something binding the thread, usually there's a more erratic look to it. Probably not the issue here, but I'd still check that (takes seconds).

How to fix this issue, this time -- first GUESS, I'd try one size larger needle.

[cleanview]

very interesting. i was under the allusion that The smallest hole the better, but what you says makes perfect sense.

that pic is 207 thread in a 23 needle. I will put in a 24 without changing anything else and see what it does.

Can you explain by what you mean when you say the bottom stitches are low? I would think that means the knot but would like to be sure.

[JLSleather]

As a rule, I like to use the smallest hole I can get away with. And I generally would use the 23 with 207 just like you said. Still, not all threads are the same, etc. Since that's such a simple fix, I'd start right there. I mean, if you get too big a hole, and the issue isn't fixed, it's simple to put the other needle back.

And yes, 'low' meant the knots. If you've verified it's not the needle / thread size combination, and the thread pulls smoothly from the bobbin, THEN you can turn up the top tension a bit.

You already know to make sure that there's nothing keeping the feet from coming all the way down (lever up, chain binding, etc). Point was, don't assume the worst.. it sometimes is pretty simple. I've ran the bobbin right out of thread.. top tension ALL out of whack when that happens.

[cleanview]

Well no pics tonight, but do believe I have made some progress in setting it up and have to admit I am not sure if I will have the never to change it for the next thin holster I do. I guess I can just count and record and "in theory" put it right back when needed.

One last question......In all this I have learned a lot and have figured out a bunch through what you all have told me and observation, but for the life of me I can not see how the second tension disc (counting from the spoor of thread forwards) has any affect on the tension. The nut tightens the spring but it seems to have zero affect on the tension off of the disc. I dont think that the disk spins (it does not clasp the thread like the first one does). It looks like its there to tinker with when you just feel the need to tinker with something.

Well, some one will tell me or in some not to distant future it will become apparent.

Thanks once again

Think of the bottom roller as a kind of momentum brake. The stroke of a 441 machine is very long and quite violent at at the moment the take-up changes direction. Without some type of damping, the top thread could develop slack fro shock in the wrong places resulting in unpredictable thread binding hassles.

As the thickness of the thread increases, the affect that the bottom roller has increases. It can add to the overall top tension due to friction between adjoining windings.

The bottom roller disks also maintain a smooth flow to the check spring.
