Constabulary, I did not find an e-mail from you.

Is this where you sent it?

@AmyP I think maybe you're conflating a very old message from Constabulary to a different user.

But, let's tag him in and see if he can help you out - @Constabulary, are you able to help Amy Pond?

Have Constabulary send you copy of the manual.  Bobbin winder looks complete.

Glenn, here is a picture of my bobbin winder. I think it is stored on the back so it doesn't get in the way. I did find where it goes, directly under the hand crank. I don't think I'm missing anything. But idk for sure.-Amy

You get a copy of the service manual from Constabulary?

@AmyP, there's some kind of  manual here, if it helps:

@ wintertree - although the thread is a little older.

 

As constab said - the Adler 30-7(0) uses the long 332 LG needle (48,5mm long)

Although he gave you the wrong specs.

A 332L needle is the short 332 needle for leather (L) as used in the 30-1 and 30-15

The needle you need for leather for your 30-7(0) is called 332 LL LG - very important - the LG stands for Lang (long) the LL for Leder Links (leather left sided slot)

For fabric the needle is called 332 LG (without the LL)

Make sure when you buy it in a shop to take along a vernier caliper and make sure that the length is 48,5mm

Then install the needle in the needle bar, open the cover plate and watch how the hook interacts with the scarf of the needle/thread when you turn the hand wheel.

If you have the right length needle and the hook and scarf do not interact as needed - you must take the machine of it´s table/stand and from the underside you will see a coupling at the 90 degree bend of the drive shaft.  Inside that coupling is an excentric bushing. You need a 16mm box end wrench and a screw driver to loosen the bushing and then turn it to the point where the hook will meet the middle of the needle scarf when the needle is going up while cranking the hand wheel. This sometimes takes more than one try(and a coffee and smoke of your choice to keep calm).                      Since the 30 series Adler do not make top speed, it is okay to have the hook meet the scarf in the middle - on very high speed machines you would want the hook slightly above middle - that is what I was told, although I have never sewn on a high speed "thread runner".

Also there is a second screw above the one that mounts the needle to the bar - the needle positioning screw.

With this screw you can position the needle scarf closer to or farther away from the hook - although side travel here is very limited - but sometimes a "smidge" is all it takes.

 

Also the 30-7(0) is very "finnecky" where it comes to the adjustment of  foot pressure AND the little take back spring for the top thread.

If those two adjustments are not in perfect harmony - the stitches do not look good.

I own a 30-7 and sometimes it is a real PITA to get them both just right, especially if you work on different thickness leather in one project.

My Singer 29-33 is more forgiving in that respect - it does not require as much adjustment to produce a proper stitch.

The one advantage of the 30-7(0) though is the large bobbin - which can hold about twice the amount of thread as the Singer 29-33 bobbin with 20mm diameter.

Although this is comparing apples to oranges - the Singer 29-70/71/72/73 series have the larger bobbin as well.

 

Hope that helps you out

Greetings 

Hans
