Uwe, what is the diameter of that hook shaft?

Regards, Eric

I have an original Singer hook out of a 111. If you verify the shaft diameter and the diameter of the cam that drives the latch opener, it's yours for the cost of shipping.

Regards, Eric

Eric, the shaft diameter of the hook in the Consew measures 9.5mm, the cam measures 12.5mm in diameter. I appreciate the offer of the genuine Singer hook - but hold on to yours for a little while longer. I just picked up a Singer 111W155 in St. Louis last weekend - my first ever genuine boat anchor with a bent main shaft, I think! On the plus side, it has an original Singer hook in it that I'll investigate. That Singer 111W155 boat anchor was fortunately accompanied by a gem of a Pfaff 545C H4N10. It all balances out, I guess.

Constabulary, using a Dürkopp 239/241 style hook in a Singer 111 class machine sounds like a very promising path for a "proper" fix and a nice upgrade - I'll have to look into that! Do you have a part number that goes with that Dürkopp hook (and shaft)? HDU249 seems to be the compatible Hirose part number.

I know there are alt least 3 different hooks for the 239.

One is for small bobbins and has a bar across the bobbin case like the 111w hooks have, one has a bobbin case cap like Pfaff or Adler and the 3rd is a large size hook with cap. I think the one you linked is the cap type hook but w/o the deflector tin and shaft. But I think it needs a different hook saddle. Here is a picture from an older 239 parts list.

Maybe this one could be an option but it´s just a guess (because of the extra deflector)

I ordered the cheap HDU-249 from Ebay yesterday just to have it on hand for a closer inspection and to explore.

Constabulary, I'm curious about your specific Singer 111G156 setup with the DA hook. Did you do the change-over yourself or did it come that way? Did you have to replace the hook saddle or other parts, or is the hook+shaft a direct drop-in replacement on that machine. Any pictures of that setup would be greatly appreciated!

I couldn't find your DA OEM hook on DA's sew24.com parts website. Perhaps I wasn't plugging in the right part numbers. Where do you buy your DA OEM parts?

I'm also striking out on a source for the modular shaft that goes with the hook head.

The Cerliani website is a treasure trove of hook related information!  

Hooks like that Hirose hook (HSH1215MM5) you found with the extra deflector are also made by Cerliani. They call it the heavy thread version of that hook.

Drop in replacement more or less. The 111G156 came with an OEM Made in Germany Singer hook with fixed shaft (the one in the picture) but I once restored a Duerk. 239 a while ago and that machine came with a bunch of extra parts incl. some hooks. The mechanic of the two machines looked very similar and my Singer hook seemed to be a bit worn though it still worked fine. I just gave it a try and it worked well. Only technical difference beside the replaceable shaft is that the Singer hook has a slit in the shaft for the set screw whereas the Duerkopp hook hasn´t (hook saddle and gears are the same with the same set screws).

Recently I have replaced a needle bar on a Durkopp machine with a 111 needle bar from College Sewing - worked well. So I know for sure that many Singer 111 and Duerkopp 239 / 241 / 245 (245 is needle feed)  parts are interchangeable. They are also using the same feet.

I saw a Singer 112W140 double needle machine this afternoon that also had a hook with the improved needle guard design. Looks like a good candidate to me, but I'm not sure it would really fit or work on a Consew 225 or Singer 111W155. If anybody has these in their stash, a quick few measurements would be appreciated before I gamble money actually buying one.

All of the sudden there's a bunch of hook candidates! The Singer 111W151 hook (part number 240240, available from Sharp Sewing on Ebay as of June 2016 for ) looks very promising, too!

Uwe, I have been battling this issue with my Singer 111w152 and Seiko STW-28 double needle walking foot. I couldn't confirm the exact cause until I watched your video. I created my own style thread guide to remedy the problem. I designed them in CAD and used a CNC router to cut them from .027 plastic. They are indexed in place with thin double sided tape. PM me your info and I will send you a few guards.

Thank you @mashoolle for sharing your solution to this problem and documenting it so well! Nice work on that custom part, it looks very professional. I did some prototype milling with Delrin plastic and it's a great material.

It's been a while since I started this topic and I now realize that I neglected to follow up with the fix I eventually came up with back then. The original little tab I had initially used was not satisfactory. After some more tinkering and online research I found arbor shims at a tool supply company (Production Tool Supply) that were just the right size and thickness. With two drops of super glue the arbor shim also worked quite nicely for keeping the thread from getting caught under the hook.

Here are a few pictures of my arbor shim fix/hack:
