D-9 needle

 

I was given a needle from a package labeled
GROZ-BECKERT
? 10? Nm90/14
DB X 1

16 X 257
71 X 1
16 X 231

that I had high hopes of it working - it did, BUT I had to drop the needle down a tiny bit to get a good stitch.
It's an old machine, who knows what it has been through. I have needles off 'the bay' that claim to fit, but I will be happy with anything that makes it work.
It still needs a lot of cleaning and TLC yet. I am looking forward to a quilt put together on it.

Hi Riley;
The W&W needle has a shank diameter of 1.75 mm & a length to the eye of 38.9 mm, whether the round shank or the one with flat. A DBx1 needle has a round shank of 1.64mm with a length to the eye of 33.9 mm. Thus the DBx1 needle is 5 mm shorter than the original W&W needle & the shank 0.11 mm smaller in diameter. This converts to a bit over 3/16" on the length & a bit over .004" on the shank diameter.

I habitually use the DBx1 needle in my #8, #9 & I also have a late Singer 9W7 which uses the flat-sided bobbins that will accept one also.? On none of my D-9s will the needle pass the alignment screw near the bottom of the needlebar. Apparently, this screw is just a tad shorter on this particular 9W7.?

One does as you said have to pull the needle down in the clamp & also align the eye. After doing this I can tell no difference in the stitch quality with the DBx1 needle in comparison to a regular W&W needle. Another option on the machines which will accept the full-size shank is a 128x1 needle. this needle has the 1.75mm round shank, but the same 33.9 mm length to the eye of the DBx1.?

The 128x1 is readily available at a reasonable cost but not quite as economical as the DBx1. As the difference in shank diameters only shifts the needle blades C/L by 0.002" (Half the thickness of a sheet of 20 lb printer paper) I have stayed with the DBx1 rather than going to the slightly higher priced 128x1.?

Some people use a UY 118 GBS or GAS needle in these machines as it is almost as long as the W&W needle at 36.6 mm to the eye. The shank diameter is however only 1.52 mm so the needle shaft is shifted away from the hook by over twice the amount of the DBx1. I have fears that particularly when using a small size needle with lightweight thread it might result in some skipped stitches, so have stayed with the DBx1.

Thank you sir!
