Adler 30-70 advice

[24602]

Newly acquired minty 30-70 is sticky in the foot rotation. Much of the rotation is fairly ok but definitely seems it should turn much easier and smoother.  Normally I dive right in and disassemble things but feel a bit intimidated by this one. So my question is how to get the rotating parts out for cleaning?

I have a mechanics instruction for the Class Adler 30 but file is too big to attach here. Send me you email address by PM and and I can forward it to you.

Basically you have to remove the tapered pin which attaches the needle bar to the slide piece on the lever arm tip (hammer it out back to front - in best case 1 gentle but feisty hammer strike should do it), loosen the stop thumb screw on the front side of the head (if present if not go ahead) then remove the 4 screws which hold the head to the main casting. Now the head is free. Pull out the needle bar from the bottom side. Then remove 2 small screws you see on the round cap piece the needle bar goes through. When done you should be able to pull out the revolving inner part from the bottom or push out from the top.

Before you go tearing it apart you should try putting some good penetrating fluid around the outer part of the washer w/2 screws in it @ the needlebar should free it up.

I agree Bob.   Put the oil to her and let it sit.  The penetrating oil will loosen up any old oil, grease, dirt. etc.

What is ‘good’ penetrating fluid?  I’ve been putting oil down there and it seems to get a little better but goes back to sticky after a bit of spinning the wings.

Another thing I’m not sure how to fix without decreasing character and value is the rust on the lower step of the table. Assuming there is no Adler green paint I thought to just cut a thin rubber mat to cover it. What would y’all do?

PB blaster or WD40 should dissolve the old oil & free it up.

The rust on the stand should be wire wheeled or sandblasted.  You also should try Evapo Rust. Great stuff.   If it was me and I rebuild these machines, I would disassemble the stand, de-rust it,  get an automotive paint mixed to duplicate the color, paint it and re-assemble it.  Looks great and increases the value of the whole machine.  It needs a drawer and i have the plans to make one as well as a couple on the Adler stands

I have,

thanks Glenn,  you cannot see it because it blends into the cabinet behind but it does have the drawer. I found it in a box of stuff  the seller gave to me. 

Thanks for the paint idea.

The foot rotation does not want to loosen up.  I’ve been giving it the wd-40 and turning it around but it isn’t changing. Actually it gets worse at times. It doesn’t help I’m not sure what it should be like but I’m sure it shouldn’t be as tight as it is and shouldn’t get tighter at times. Any advice.

Some other cool stuff I found in the boxes of stuff that came with the machine. 

There were a couple of other non Adler (maybe not even sewing related) items as well.  Maybe will show some photos in another thread to see if anyone knows what they are for.
