Adler 20-2, Anyone Here Using It?

[Constabulary]

Looks like your needle bar is set to low. Is the needle all the way up in the needle bar?

Not sure If one has mentioned it already but the loop will be formed in the upwards movement of the needle bar. At the point where the needle bar goes up again there will be a loop that the hook has to catch. The needle bar has to make this small upwards movement. This is the critical point, if the loop will not be formed properly the machine skips stitches. This point is where the hook should catch the loop / meet the needle scarf at approx. 2.5mm above the needle eye - remember the upwards movement of the needle bar is important!!!

@Constabulary: I am fully aware that is the way its supposed to be, but this picture wasnt taken at that point in the needle cycle either. This is just before the needle begins its upwards motion again and the needle bar is as high as I can physicly set it on this machine. Most of the time its's working as it's supposed to do but then again, there are some missed stitches so I will have to fine tune it in some way that doesnt involve moving the needle bar further up.

okay - one more thing I "could" image is that the thread take up lever pulls the thread at the wrong moment.You know what I mean? When it pulls the thread up at the moment the loop should be formed there will be no loop or a too small loop. But thats just an Idea, not sure if it possible...

[VanRhodes]

The thread take up lever is controlled by a cam that is pinned to the drive shaft, same goes for the shuttle and its drive shaft so I doubt that I would be able to affect the timing on any of those components. I will have to study the parts diagram again and see though. Had I been able to affect the position of the shuttle like you would on a normal sewing machine it would have been a rather easy fix, but all of this is locked in position with pins. Will have to test other options.

VanRhodes,

Have you solved this issue? My longbed Adler 20 has the same issue. After a good cleaning it went better. But sometimes the hook doesn't 'fall' back past the needle and sits still exactly in front of the needle resulting in a missed stitch. 

Not working on the machine right now, but just curious how/if you handled it.

To be honest with you Sandyt, I solved it by reshaping the hook. I shortened it a couple of millimeters with a dremel and it's now working perfectly. I figured I could give it a shot since I got an extra hook with the machine. 

[sandyt]

Haha, why not indeed. Too bad I don't have a spare hook. If I can't fix (re-time) my machine, I will try the same probably. 

It's strange though. All the shafts are pinned. The timing can't be off. Maybe the previous owners placed the wrong hook in it? I don't know. Hope I have time soon, so I can play with the Adler

Thanks.

Sandy.

[VanRhodes]

That might be the case for my machine since its using SIMANCO parts for the shuttle, hook and driver. This would explain why it might be a little bit off in timing. None the less, shortening and reshaping the hook worked like a charm so give it a shot.

Here are the guides I found.  Not sure if you have these already.  I am going to restore my 20-2 in a month or so, but its made with Singer 7 parts.

I've got two of these machines, complete.  In case anyone cares.
