Dürkopp 18 Patcher Restoration - long journey...

[Constabulary]

The Dürkopp 18 is a quite unique patcher machine because it has a very narrow tip and can sew in very tight spaces other patchers probably would not be able to reach. It also has not an oscillating / elastic hook like all other patchers. Instead it has a "boat shuttle" in a fixed position and a "thread hook" which grips the upper thread pulls it back and thread slides around the shuttle and is forming the knot with the bottom thread (basically). This Video shows is quite good (not my video):

Almost 1 year ago I found a quite rare Dürkopp 18 patcher head on Ebay. This actually was the first I have seen with a front crank - all others I have just had the side wheel. That was the main reason I bought it. So far - so good. Bought the machine - paid it - seller shipped it and that where my journey starts...

The seller seemed to be not very clever - though I gave him clear instruction how to pack up the machine he did not listen and even worst - he shipped the machine up side down (I told him to put arrows on the box). He put the shipping label on the wrong side (bottom side) of the box so the machine traveled flipped up side down and its obvious what would happen - the delicate top parts broke and the needle bar bent. Needles to say that parts for this machine are no longer available

This is what I have bought:

And this is how the machine arrived:

 

I disassembled the machine to see what parts actually broke / bent and that's how it went under the work bench and started collection all forts of dust and dirt again for almost 1 year.

So the only way to get the parts I need is a 2nd machine and after almost 1 year I finally have found one within 1 hr driving range. Unfortunately - this one is totally rusted and seized. but the good thing is it came with a stand. Some pictures:

 

So I started restoring the stand first:

Drawer was quite good it just needed a new bottom - obviously. Washed it out with soda solution took it apart put in a new bottom and assembled it again. On the Dürkopp logo is still is the original gold paint I just put clear coat on it.

 

After I took apart the stand I de-rusted the screws washed off all the dirt and gunk in a bath of soda solution I painted the stand with Hammerite and put some clear coat on it - turned out quite nice...

Next is the machine head... but that way take a few more days.... to be continued

The stand looks great! Good start.

so far these are the damaged parts I discovered... Maybe there are a few more - I will find out when I start cleaning and reassembling everything.

I admire your patience, and it is paying off.   You've done a lovely job on the stand.

Having had a machine posted to me badly packed (I also gave explicit instruction on packing the machine, all of them completely ignored), and having to gather up the broken bits of a 130 year old machine, my heart goes out to how you must have felt opening that box.

Some folk need a good drubbing.

I swallowed the anger a while back already but when I look at the pictures I´m still a bit pissed. But its just a machine...

The Class 18 was in production at least until 1943 so this one (or both) is / are not "that old". The model list of Dürkopp and Adler machines (see PDF attachment) show that there was a change in the needle system of the Class 18 in 1943 - they switched from Sys. 88 to Sys. 332 LONG - like the Adler 30-7 uses. I would guess my 1st machine (the one I restore) is from the mid to late 1930´s. I heard a story that the production of the Class 18 (and other machines of course) stopped because the plant has been destroyed during an allied air raid. But afaik that was in Sept. 1944 - maybe parts of the plant got hit during earlier air raids already because Durkopp also produced weapons and other armaments during WWII.

1st one with the hand crank is the earlier one cause it has a lower serial number. Just noticed even the machine castings have small differences.

BTW - I think the Dürkopps must have been proud of his machine - the two crank knobs are made from porcelain and not plain wood.

What a fantastic hook mechanism! That will be a beautiful machine, the green one in the museum video is gorgeous.

Good Work! Constab....

 

Its funny, some people's idea of good packaging.  I had one person tell me they were going to pack the sewing machine well only for it to turn up in a box a quarter full with sawdust...? And yes, it was broken as a consequence.  its seems some people are not willing to listen.  Still, it looks like you are progressing well.

 

I have had good results putting on Hammerite with a small sponge roller.  It was much better that using the 10 Euro special brush I bought for it.

 

Keep up the good work.

That was a bummer! i know exactly how you feel Folker? did you buy it from Australia.... that treadle looks great! and its not SILVER!!. now at least you have found the parts to get it going. some people do not realize that you cannot leave a machine loose in a box! anyway here is a very good solution that was sent to me last week. i had been looking for a skiver for a while and finally got one and this is how it was sent...

an old fruit crate! so i would give 10 out of 10 to this guy, all arrived safe and well. so if anybody is going to send a skiver this might be a cheap and good solution. nice work again on that stand Folker, hope to see that old iron going soon.
