Singer 45k25 stitch length

Recommended Posts

The longest stitch I’m able to get is about 3/16” , the adjuster  moves smoothly and goes from tiny to this. I’m using 23 needle 207 thread. 
Should be able to do bigger?

That sounds about right, 3/16 - 2/8ths - 6mm. When the feed dog wears the stitch normally gets shorter as it does not pull the same. I think the flatbeds have a longer stitch?

All of the early black oscillating crank drive Singer work basically the same.  From the 31-15, 44 series to the 45k.

They have conical bushings (bearings) these can be adjusted for wear.  That is the first you do take up the slack.

Next check how much clearance you have fore and aft of the feed dog. If you have have clearance you can do the following.  Grind the slot further down on the stitch length selector about a 1/4", go slow since you don't want the feed dog to  interfere with throat plate at maximum length.  

Also of note you can lock stitches on these machines by simply going to zero and make a few stitches. (embroidery machines work that way)  Also note if you put a servo with needle position you can back tack with ease by setting servo  at the  point of thread release.

Also if you glue a pc. of 2mm Teflon to your foot it will reduce surface tension.

Have done this and it works !

This is one way I lock starting and ending stitches if I don't want to, or simply can't backtack or spin the work around. I call it double-tapping the stitches. With two knots buried in the same hole they aren't coming out any time soon.

Ok, thanks. I’ve heard of patchers doing 1/2” stitches I think, so I thought this might supposed to be able to do that too.

The ga5-5 which is a clone of the 45k25 shows 3 1/2 stitches per inch and the feed dog and throat plate are interchangeable so it might work on your machine, A search on Isaacs may help.

I think that Claes are the only patchers that can do longer stitches than 4 to the inch. Singer patchers are limited to 5/inch. I used an Adler 30-70 that was capable of 4 to the inch. My Adler 30-7 can't quite give that length but comes close.

I have never seen a patcher sew 2 to the inch. It would have to have longer legs than the long throw Adlers.

However, two of my patchers have a T bar on top that is used for darning. This lifts the foot off the work long enough to pull it for long stitches.

Like others have said make sure there's no play in any of the parts.Then we used to drill a hole just beyond the bottom of the slot & take a file or grinder & open it up so you have a longer slot & this will make the stitch length longer.

the cutout in the needle in which the feed dog moves can limit the stitch length too. There were 45K needle plates with shorter cutouts and smaller feed dogs. maybe you can post some pictures of your machine and how it is set up.

Thanks guys, it sounds like it’s probably ok then. I don’t really need it to do those long stitches, I just started wondering if there was something wrong with it, since I had read about bigger stitches on other machines.

Yeah, sorry for the small picture of the 45k21 courtney but you can see it says max stitch length 1/4 "
