Adler 30-7

[Tigweldor]

Bought this machine last week in Wuppertal for 55€.

The sewing head had not seen oil for a long time - it was seized and had a broken part.

So I bought a Singer 29K-51 for 20€ (with table) - although it had a broken off casting lip, where the take up lever for the presser foot mounts.

BUT : the entire sewing head from the 29K-51 fits 1:1 onto the Adler 30-7 --- actually, had it not been for the broken casting and the missing lever - I could/would have converted the Adler 30-7 into an Adler 30-70 with the 29K-51 head.

The main reason I bought the machine was because it has the larger bobbins - besides that it can´t do more than the 29K-33 that I have mounted on a motorized stand.

 

If you mount the thread spool horizontal - you can use the bobbins with a cone foot - they will not fit the stock spool holder and will also hit the arm if you force them to fit - then they do not turn freely.

 

The only thing I have yet to fix is that the foot take up lever drops down too far and thus blocks the rotation of the sewing head - but in the last pic, I took up all free play by hand - I just have to weld something to the lever end so it does not slide into the slot of the head casting and all will be good.

what part broke on the Adler?  I have parts for Adlers.

Like I said - I took the part from the Singer 29K-51 - it fit like a glove - a 100% match.

Attached is a pic - the ring had broken right off the "drive bar" with the bushing/bearing on it - I did TIG weld it back into place, but on the top inside of ring there was parts missing, so the revolving part with the two handles on it would hang up once in a while.   Quite annoying that matter.

Here in Germany, you can get 29Ks for small coin - I paid 20€ for all the spare parts needed in form of a 29K-51 - plus I got a working Singer table with treadle that runs like day 1 with it.          Okay - admitted - I did have to drive nigh on 200 klicks round way to boot - but on all Sundays of the year there are no trucks allowed on the Autobahn (only those transporting perishable goods) - so a guy can mosey along pretty smooth with that much less traffic.

So now I will mount the Adler 30-7 onto my custom motorized stand and mount the 29K-33 onto the Singer treadle table from the 29K-51 - needs a plate on top to enlargen the table though, because the "footprint" of the 29K-33 is a lot larger than that of the 29K-51.

But thanks for the offer

ring is broke in your picture

[Tigweldor]

Yup - it sure is.

This is a picture of the defective but crudely repaired part.

If I were to live 20 klicks south of Timbuktu where no spare parts are available, I might have tried to weld up the missing piece inside the ring and then try to grind it smooth.

BUT : time is also money - so why bother, when I was in the position to buy a complete "parts machine" for 20€ - with a singer treadle table to boot for that small price ?

Not only that - I wanted to point out that the Singer 29K51 head fits 1:1 as replacement for the Adler30-7 head - the only difference being that the foot pressure spring on the Adler is external on the back of the machine (spring bar) where as the 29K51 has a coil spring right inside the head to accomplish same thing.

I thought to have pointed out all of this in the answers before - but then again, English is not my mother tongue so it may not have come across clearly.

The part in the pic has meanwhile landed in my scrap metal bucket, as I have no further use for it - with not a single tear lost over that act.

You can use 2-pieces of angle iron,I use old bed frame cut the length of the legs to extend the mounting surface on the short top.

Hi Bob,

Thanks for the tip - I  will definitely use it / do it that way.

Got lots of 40 x 40 x 5 (= around 1,5 x 1,5 x 3/16 in inches)  angle iron in the shop.

It looks like you already unseized your machine?

I recently bought a Seiko from Japan that was seized up. It hadn't been used since the year it was made, 1986!  Locked up tight, just like you used superglue instead of oil.

I used a few drops of PB Blaster (Penetrating oil) on each joint, bearing and oil hole and then sat it up on blocks above a gas freestanding heater in my shop.  I left it there a few hours, until it  was pretty warm (not hot, just warm enough you'd want to not keep your hand on it for more than a couple seconds). I took it down and everything moved  a little. After a couple extra drops, it spun freely.  

I don't know if you'd really need the heat, but I found it helped allot with the polymerized oil.  

 

Looks like a great buy for $20 Euro.  I always liked pre Durkopp Adler machines.   Really great build quality.

No - I bought the "naked" Adler for 55€ in Wuppertal - + 200 klicks of driving. The seller, knowing that there was a broken part and not having told about it in the ad, had either hid in the house or had fled - his mother was there with the machine in the driveway - needless - I would have bought it even with the broken part.

I found out about the fault at home - so I needed a fix for that.

Exactly cause of that, I bought the 29K-51 with pretty close to 200 klicks of driving the next weekend in Meschede for 20€ - but this time the sewing machine came with a treadle table - but with a broken casting lip on the foot take up lever.

This was a chance buy - but it worked out - parts from both machines were a 100% match - could have been completely different.

I could have then sat there with two useless duds on my hands and little to show for cash and time and effort.

But if you don´t take a chance once in a while - life will be dull.

So all in all I spent 75€ plus 400 klicks in my car (Kangoo = around 10l/100km at 1,7€/liter = around 70€ gasoline) - i don´t regret one single hour or one single Cent.

This is not counting my time, as I wanted a patcher that could handle the bigger bobbins.

Every old sewing machine i get - I FLOOD with oil.

On these old patchers I take the sewing head off right away - that means removing 1 pin at the swingarm and 4 screws at the head.

Then I take the head apart.

You force an old machine to turn while stuck/frozen - that usually means that something is going to break - that will cost you more coin - completely unnecessary - like a young spud on his first date with no patience. (grin)

I´m nigh on 63 years old by now - I have learned what patience is - used to be the exact opposite when I was young - take my word for it - I did force a lot of "things" that "broke" while doing so - and regret a many of them.  That is the main thing bad about hard core biker life style - but even after having turned into a realist, I do not like to be taken for a "softy".
