Singer 411G, Singer 401G and a Singer 401A Slant-O-Matic Singer machines
 

I will have to do about one picture per little window here so this doesn't crash - please be patient.

I have a fascination with the Slant-O-Matic Singers. I've been very blessed with several different ones. I am hoping to load some pictures to show just how different they can be.
My Singer 401G was one I found in the trash. He isn't very pretty - mechanically he is a wonderful machine. The Singer 411G is much prettier but she has a couple broken spool pins. Notice that the fasten on different than the 401s. The Singer 401A is what most of you know and love and it, too has a broken spool pin.

Ok now you have met these machines. Are you ready to look at the details?
It will take me a little time - please be patient.

Singer 401G is pretty much like the 411G but the printing is pretty much all worn off the 411G [ATTACH=CONFIG]388879[/ATTACH]

The noses are similar but oh so different. Singer 401G

Singer 411G - this can be threaded to make a chain stitch! Note the threading diagram is different from the 401A

And the Singer 401A nose [ATTACH=CONFIG]388882[/ATTACH]

The tops of the G machines are different than the A machines, too - the bobbin is wound at the top of the G machines and on the front of the A machines.

I will show some detail about the treadling for those who are interested. The 401G is set up to treadle. The 411G is able to treadle but is not set up to treadle at this time. The 401A might need some major modification to treadle.

OOPS I forgot to put up a picture of it with the treadle belt.

The belt goes through the front of the machine and down to the wheel through a knock out in the bottom of the machine. The back goes through a channel in the back of the machine.

The fronts of the machines are similar - you can see the place to knock out in the front of the 411G

The back of the G machines have a channel for the treadle belt.

The bobbin race from the Singer 411G has a little hook so that it can make a chain stitch

take a closer look at the threading on the front of the 411G machine[ATTACH=CONFIG]388891[/ATTACH]

Do you see a hook inside the nose door? extra thread guides outside?

maybe later I will post some more pictures

thanks for this! Sorry to play the ignorant card.... what is the difference between the G and the A of the same model?

Oh I'm so sorry - that should have gone on the first window... The Gs were made in Germany and the As were made in America as far as I know.

Great machines!

With feature differences too.
401G - treadle ready - 401A not.
Are there others Miriam besides color?

The maps on the doors are different. Lots of cosmetic differences.
Check out the stitch length regulator differences.

and the 401G

The German machines are badged on the lever plate.
The bobbin winds at the top.
there are treadle belt channels in the back and square knock outs with space for them to go in the front - the hand wheel is deeper.
Extra thread guides
Different shape to the top & doors - a bit different shape to the front nose door
lots of little differences.

The 401G was a trash day rescue a few years ago - I had to learn the hard way not to use liquid wrench, anything you spray in... WD40, 3in1 oil - it was dirty, rusty in places and locked up tight - I never really dreamed it would sew or was so special. I worked on that one for two years before I got everything working right. It still could use some more clean up. The motor is cracked. Speaking of motor and electric. The G models take the same foot control & cord as the Singer Featherweight - one plug two cords. The 401A takes two cords with two plugs.

zzz picture failure so I had to delete it

That was the 411G I think what pic I took of the 401 is above somewhere.
Inside the 411G disk cover door - note - the spool pins are broken and someone tried to fix them - the printing on it is very hard to read - the 401G is much easier to read.
picture failure so I deleted it...

another duplicate so I deleted it

zzzzz this was duplicate so I deleted it

sorry - some times I think I over do on pictures and things go haywire

A link - how I treadled mine - I would for sure test out t spinning wheel belt before I ground off anything to make it treadle.

MY old ones look like these two in the picture together. they have sewed many a mile of seams.

Thank you so much for posting all of this information, and for all of the pictures. I have read about the German machines, but never seen one. Now, I have a much better idea of them. I, too, am a vintage machine aficionado. And sad to say, a collector of them, too. If only I lived in a castle--I would have enough room for all the ones I would like to have!

Just pretend it is a castle...

I broke my spool pin and purchased an inexpensive water color paint brush, plastic. I cut it in two piece and it works well as spool pins.
