Adler 69 Reverse Stitch

[vericone]

When I was adjusting things on my adler 69, I've got problems with reverse stitch. After finding solutions on youtube I've made some adjustments, but I've lost the stitch length.... Two days I was struggling with a reverse mechanism, and I've found something strange - the plate, covering a slot in which the reverse stitch lever was moving, was smaller than the slot in the cast itself... reverse lever was stopping on the plate, while there was a place to travel a bit more. I've cut the plate more, to fit the slot in the cast. Now the machine works fine on reverse with full stitch length.

It's quite possible that the plate have been replaced in the past, but maybe this hint can help someone.

On the photo there is a mark showing where the slot was ending before cutting it to the bigger size.

Mine is 372 and I see the difference. Now mine goes with a stitch length of about 4mm (on about 3mm thick leather)

[piheart]

373 is 5mm.

I have question, my reverse stitch - when max forward stitch is 5/6mm, reverse stitch only 4mm. when forward stitch is 4mm, reverse stitch is still 4mm which is good that two threads matches. forward stitch 3mm, reverse stitch is 3mm too. how it lost 1mm at reverse max stitch? anyone knows how to fix?

I checked the leather that I used when I testing this machine from ex-owner, is also 1mm shorter, so I don't think is because I unscrew the nut little bit on top.

Thank you guys!

https://youtu.be/0hLbNx3dGkY - this is a good video about reverse stitch calibration.

Thank you vericone! I have done that yesterday, still gets 4mm at reverse max.

Good way to set proper reverse stitch is to understand how the mechanism works (it was in my case ) When You open the arm cover You will see that when the stitch length screw is set to max stitch length, the upper side of "funny shape thing" rests on the screw. When You set the machine to reverse, the other side of "funny shape thing" rests or at least gets near the screw. Now You see that the screw is the point where the "thing" achieve its borders - from one side max forward, from the other max reverse. Now the most important - when setting the reverse stitch length You adjust the position of the stitch length screw. It is not about how deep it goes to the iron cast, what matters is that it can be higher or lower. I'm not by the machine now, but I think that if the hole (for stitch length screw) is higher, You get less forward and more reverse, hole goes lower - more forward, less reverse.

Hope it helps.

Hello, I bought Adler 69 sewing machine, used, a while ago, and noticed that backstitch was millimeter shorter than forward.

I did the reverse stitch calibration like in the video above, and now it is equal to both directions.

BUT. With the covering plate mentioned in the first post I got stitch lenght about 4mm, but when I took the plate off, stitch lenght is 5mm. Both directions.

So, does anybody know any good reason why I should leave the plate on?

Picture below shows the offset when backstitching. There is enough room for forward stitching in the plate.

Thank you for all the info posted above.

Boy, am I glad that I chose Pfaff 335 over Adler 69!

And I was thinking of going back and trading them to have a larger handwheel that Adler has over Pfaff. Won't do that now.

I am happy for you, as I'm happy for me: there's no problem with sewing at all with my 69. It's workíng nicely, only strange thing is that why is stitch lenght limited by cover plate, not the mechanism itself...

Vericone: you have had any problems after making the slot bigger?

Personally I chose Adler over Pfaff because it's so much easier to pronounce.

Well, really I got a good deal with this machine, with servo motor with needle positioner installed.
