Would Appreciate Your Advise On Restoring This Singer 45K25

[Evo160K]

Hi Darren,
Good questions. Why get hung up on that thread? We used that thread regularly years ago in our business to sew Kevlar sleeves onto high temperature Textoglass (fancy fiberglass) mittens for use around molten aluminum. We sold the business, so I'll most likely never sew with it again, but I'm just curious enough and stubborn enough to want to find out what's making it break. I tested the breaking strength with a scale to 12 pounds (5.44 kg); Would you think that would be strong enough to penetrate 8 oz. (3.17 mm) veg tan with a 23 round needle? It's been an issue for weeks and I can't figure it out.


Hi TinkerTailor,
You certainly have an uncanny way of seeing through to the heart of the matter. Btw, you're correct, we do have a lot of that thread left, but that's incidental. Like you suggested with that well chosen mouthful of words, I want to learn.


Hi Jimi,
That's a good thought. That area of the shuttle race could be the cause, I can't tell. It and the other parts don't feel rough. Do you see anything in the pictures irregular or suspect on the shuttle race, the inner race or the shuttle?



Gentlemen, would you please take another close look at the Third third video, the last one? Do you see the slight beginning of a break in the thread, just before the midway point in the video, and before the thread reaches the right end of the shuttle race? If that is the beginning of a break, would you think it happens before it reaches the shuttle race or as it passes the shuttle race the previous rotation or two?

I'm trying to install and upload using dropbox. Once I figure it out, I'll post a better video showing what's happening. Ok, let's look at this video:

Thank you all

The video you want to share. You have to put into the folder named "public".

It's quite long time since I spend time on Dropbox. But If this folder not already exists, you made a folder named public.

Earlier you would be able to share, to others, from any folders you made on Dropbox. But because of better security on the site Dropbox. Sharing files now, is only possible (?) from the your "public" folder.

I apologise my English, that is not as good as others.

hyttogpine,

Thanks for the information. I created a folder in dropbox called public, but I'm not sure if I did it correctly. Would you please try the link above again and let me know if the video works.

I noticed yesterday before I created the Public folder, when I clicked on the dropbox link above, it asked me to login. I closed the login box without logging in and it took me to the video which played. I believe Dropbox was trolling to hook new members, I may be wrong

This time the link works. I came to your video. So you make it right (when we talk about Dropbox).

Before I click on the video, I see a picture of the bobbin & shuttle. But on the "time counter" ? it tells 0.0 /0.1 (minute/sek.). When I click on the video, it starts to "buffer" and continues by buffering.

You are now close to the finish line.

The problems can be two things (actually three). Instead of uploading a video clip, you in a rush have upload a single photo. Or it could an issue of the video format ?

It seems like your video format is .MOV An Appel-format. I don't know these days, but earlier everything of Apple (but here and now: pictures & video) was hard to deal with. Unless you was a member of the club. If you're sure it's a video you uploaded. Try alternative to upload the orginale, before you did the compression. Or try to convert your (original) video to another format, for instance mp4, AVI, 3GP, WMV or swf.

But before you do anything, make yourself a cup of warm chocolate, watch the birds outside your windows. And wait fore feedback from someone other - without Apple equipment.

The third options : it could be my tablet. But then it would be first time it refuse to play a video.

EVO, don't despair. You have went into and learn new stuff, beside the leather world.

hyttogpine,

Thanks for your patience and encouragement. Perhaps I posted a single picture, I have no idea. Would you please try this link and tell me if it plays the video properly? Thank you.

The link and the video above is quite all right. I still can't play it on my tablet, but instead I download your .MOV video to the tablet, transfer it to a computer and watch the video easily in VLC player and by a little pushing in Windows Media player to. And it was the area I have a modest practice about?

Why your threads break I have opinions about, I'm a amateur.

Actually I'm a bit impressed of you. Well done and good luck.

I can´t see what is happening but when other threads are working I´d say the problem is this particular therad - maybe too old. I would simply not use it anylonger.

[Darren Brosowski]

Sorry about the pointed questions but it would not be the first time someone has tried to set up a commercial enterprise on the cheap!

I suspect that everything needs to be perfect for this thread. There is some wear evident in the shuttle race ring and the shuttle point.The race ring p/no 91430 and the shuttle are available new but they may not solve the problem.

How close is the shuttle getting to the needle and is there much slop in the shuttle? Try a thin carboard shim - cerial boxes are good - behind the ring to push it closer to the needle and see what happens.

Well..., aint got a clue Al.if it is not being pinched or frayed by a sharp edge... then folker is probably right, it could be that the thread is old?? did you try it in your adler 30 ??

[TinkerTailor]

It could be something stupid like one side of the spool sat with one side exposed to a window and every second foot of thread is brittle from UV exposure. Or the whole roll got dropped at some time and one end or corner has cracked fibers. It is glass.....Every time the thread gets to that corner it breaks. When you tested it you got the good part.
