Singer 45K25 Dos'nt Like Linen Thread?

[courtney]

I recently got a singer 45k25 and it sews fine with the 92 thread that I have but when I put the 3 cord barbours linen and the 25 needle it has problems.

I have oil in the pot and have messed with all the tensions, I have it on a 29 patcher stand with no motor so I can really feel it stick right when the hook catches the loop and tries to pull it up.

It works o.k. On thin leather but on belt leather it keeps breaking and missing stitches etc.

Any ideas?

Thanks,

Did you wrap the thread around the 2nd tension(on the side) 1 & 1/2 times?

The #25 needle is best used with 4 cord, not 3 cord linen. Go down a size.

Shorten the stroke of the check spring and reduce its spring tension a bit.

Remove the throat plate and watch the loop as it forms and the hook approaches it. This can reveal a lot about timing problems and needle height.

I wrapped it 1 1/2 times around the front face plate roller tension but not the top one. I looked at it cycle and it seems to stick right when the hook catches the loop and the needle pulls it up. I can feel it when I turn the fly wheel be hand, it's not that much on thin stuff but on the thicker it is real sticky right then and starts clanking when I 'm sewing

Try retarding the hook slightly, so it picks off the loop closer to the eye of the needle, as it ascends.

How would I do that?

[CowboyBob]

Is your foot lifting wth the needle & leather as the needle is pulling out of the leather? Or do you hear a squeaking noise?If so tighten the foot pressure more to hold the leather down.

No, the foot pressure seems fine,

I guess by retarding the hook that would mean moving the needle bar?

It seems like since it works fine with the thin thread, it wouldnt be a timing problem? Not that I would know. I did just bring it home from a sewing machine mechanic but it would not be easy to get it back to them.

It almost seems like the hole is not big enough to pull the thread through, but that cant be with a 25 needle and 3 cord thread.

it is right when the hook catches the loop it just gets kind of stuck, but it only does it with the thread, there is no resistance or burrs without thread.

[CowboyBob]

It wil get tight when the hook grabs the thread,do you know you need to hold on to it(the needle thread) for the first 3 stitches.Then it will hold it's self atfer that,as you sew heavier & thicker you might need more tension.If you have any try some nylon like # 207 or 277 & see what happens.

[courtney]

Yes, I have been holding the stitches. I dont have any nylon but I bet it would work better. I'm wondering if the hook on the shuttle is pointy enough? I dont know if that would change anything since it is picking it up?

Also the needle is not tottally centered in the throat plate.

I messed with the needle bar timing it seems like it works better when the hole is alittle below the hook.

Which way is the thread supposed to come off the bobbin?
