Hello
 

I have a vintage 27-4 singer sewing machine. I have been trying to learn how to use it. I have tried to thread the bobbin BUT the bobbin keeps falling off. I notice that the spring part on the left side does not seem to have much tension in it. Can this be fixed??

Welcome to QB, drkaj. There should be a screw that can be tightened, but it might be stripped or the spring out of shape.

Do you have a manual? There are several free ones on the web.

We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at https://www.quiltingboard.com/attach...020-01-17-.pdf
Don't forget to scroll over to the far right to find and click on the "Upload" button. As shown at https://www.quiltingboard.com/8565676-post4.html

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

Or simply - Make sure pictures are smaller than 2MB
Click on red "Reply" button
Click on the paper clip icon
Click browse - choose picture/s. (only 5 allowed per post)
Once they show up as being loaded, Scroll over to the right side and click on "Upload"
After the pictures show up as being attached, you can close that window and go back to the screen to finish posting your post.

Some additional notes -
The photos generally need to be reduced to less than 2MB in size. I have heard of people sending an email to themselves as it will ask if you want to reduce the size.

I have an android phone and when I tried to reply on Quilting Board while in mobile view None of the options for adding pictures was available. However, there is an option down at the bottom left of the page that is for Full Site when I tapped on "Full Site" It then looked like the way it looks on my lap top. So it would have the Red Reply and the Go Advanced options.

Do Not Preview post.

A better description of the problem might help along with some pictures of whats happening. Do you mean that the shuttle (the boat shaped thing that the bobbin goes into) is falling off the carrier?

How about you? Are the experienced with these types of machine, or are you just learning?

Is it possible that you have the wrong shuttle, or do you know for a fact that it's worked in the past with that one?

Thank You. I do have the manual, I printed it .It is the bobbin winder itself and there is no screw to tighten. I removed it from my machine and any going tomsoak it in paint thinner to see if maybe it is gummed up inside. I read that tip somewhere.
the spring is inside the encasement and I don’t thin’ the end will come off t9 replace the spring.

(this may be a double response)

Ahha! You did say "winding". I need to pay more attention...

I think you've got it right, it's probably gummed up internally. Rubbing alcohol is another great crud cutter. Q-Tips work well for getting into the nooks and crannies.

Thank You!! I will try the alcohol!

Attachment 644832I am wondering if the end of this , circled in red, comes off so that the spring inside can be replaced?

So you must still be dropping the bobbin?

I've never even looked at disassembling the bobbin winder. But it went in, so it must come back out!

You're blazing new trails now (for me, anyway). I'll look at one of mine later today and see if anything jumps out.

Meanwhile, it might not hurt to verify that you have the right bobbin. Maybe the length is slightly off. I'll measure a couple of mine today and report back.

Thank You! The bobbins are the original ones that came with te machine. They fit good but just wont stay in when trying to wind the thread on. The tension on the piece circled is not strong enough to hold it in place. The spring inside of that piece is very weak. That is why I was wondering if the spring can be replaced. I cant get the end piece off , maybe because it is gummed up or maybe it does not come off. But I really agree with your statement ---"But it went in, so it must come back out!" I really hope I can get this fixed. I have looked online to find a replacement bobbin winder but cant seem to find any. I am nervous about buying off of ebay cause there are no guarantees.

Alcohol removes the paint. Kerosene is the best when dealing with painted parts. I buy lamp oil at Walmart. Get the unscented. It's on the isle with the candles. (Our grand and great grands used Kerosene in their lamps before electricity was common.)
