Singer 45K25 Dos'nt Like Linen Thread?

[courtney]

Well, I got some nylon 277 and it seems to be working!!!! Thanks for the help Wiz and Bob! I spent way too long suffering trying to make the linen go through, But I got more familiar with my obsolete machine.

I know parts are super scarce for these but I wonder how important the right parts really are?

Obviously they have to fit, but wouldnt any heavy check spring and tension discs/springs be o.k.? The sewing mechanic that had my machine was talking about grams of the spring and stuff.

What are the parts of a sewing machine that usually need to be replaced at some time?

This machine is not obsolete my friend! The GA5-1 is nothing but a 45k21 (the 45k25 fitted with a standard foot) so they are still one of the most widely used machines on the planet for harness leather.

The problem could be that the shuttle hook is not close enough to the scarf of the needle. A stiff thread like bonded nylon tends to be more forgiving in this case.

This could be due to wear in the hook or wear between the shuttle driver and body of the machine. In the latter case I have only been able to repair it with a piece of shim but others may have a better solution.

Thanks Anne Bonny's locker, I'm really excited to have this machine! I am just freaked out because it seems like parts are so hard to come by.

It seems like the take up spring would wear or break after awhile? Could I use a techsew spring?

What other parts would you guess would wear or break?

Do the ga5-1 parts fit? I looked at their website and the throat and feed dogs look the same I think, but they said sold out and I think that model is fasted out or upgraded or something.

The shuttle hook looks a little flat from the front, it does come to a point if your looking from the back.

Should it look like a needle sharp tip from the front? My 31-20 looks that way.

The eye of the needle is way below the point of the hook when you look at when they meet, but I tried adjusting it back and forth and this is where it seems best.

The linen just felt rough and bumpy in the machine, it took so much effort to treadle it through 10 oz. you could almost hear it, and then it would break.

here are some pictures of my hook, is this what its supposed to look like?

Also, is this my retaining ring in the machine or am I missing it?

Seems to be working since I put the nylon in.

I would be pulling that bottom end apart and cleaning it out with a toothbrush and kero.

The hook surface looks a bit rough in the pic so may need a touch up with 4000 grit wet and dry.

Modern threads are much more forgiving than Linen and sometimes minor issues are magnified when using a natural thread so look at the condition of the needle plate hole.

Thanks Anne Bonny's locker, is that my retaining ring in the pic? I hope so otherwise I'm missing it.

So, the hook looks o.k. To you at the tip?

What do you think about the ga5 parts fitting?

Are there certain parts that you think tend to wear out? I cant see me breaking a needle plate but it came with one so I don't know,

Thanks,

Courtney

Courtney,

A small number of parts do fit. I believe the needle plate, feed dogs, shuttle and tension assembly are identical and as they are the only parts that ever really wear then you are ok. At some stage I will be looking at the GA5 parts so I can make anything not quite right. I have original needle plates and feed dogs in stock.

To make the needle plate work,the back hole in the plate needs to be drilled,the shuttles don't interchange either,the bobbins are the same,the feed parts interchange.The feed dog will work as long as you have the correct one as it may have been changed over the years(they must of had over 50 different combos for these 45K's)

Bob,

I thought the Chinese DD1 shuttle was the same? I have used them in a 45k with no problem.
