Hello All,

I have tried everywhere and made a few expensive mistakes so now I must get help from people who know...

I need a needle to fit my Singer 46k "fur" cup feed overseamer.

Fortunately it came with a needle already installed. It is very precious as its my only one.

The shank diameter is 1,08 mm

Length to hole 30.0 mm

Total length is about 36.6 mm

I have looked at what other overseamers use and...

None of the Bonis 292 needles fit this length. The nearest is the conu 01:30MA with a length to the hole of 27.9 mm

Tried a needle of the same period as the sewing machine (100 yrs ago)

I have bought a 12x1 needle and that does fit either.

I have looked at light industrial sewing machines and have found the following:

Canu 04:45 or 88x1

Diameter is 1.62 mm (is this going to be a problem to fit?)

Length to hole is 29.6 mm (I think this is close enough)

Should I try this one? Do you think this is close enough or can you suggest another?

Thanks for making it to the end.

Alex

Here is a page of parts lists for most of the 46k variants. There are alot of different 46k machines, which subclass is yours?

Yours looks like a 46k15 from the picture. This page list a needle size of Needle = canu 08:65 - system 459 r - 1567 - SY 6520.

Hope this helps.

Hi Tinker Taylor

Thank you for taking the time to look at my problem and the links(last one I have not seen before). It looks remarkably like the 46k24 in your link. Maybe its a later replacement for it?

The recommended 459r needles are 3.5 mm longer to the hole att 33.5mm and have a slighlty larger shank diamter of 1.40 mm. Will this not be too much?

My sewing machine is a 46k45. It is a double thread machine.

I just looked at the partslist very carefully and don't know how I missed it before as I ahve looked at it a 100 times. The official needle system is:

215x5 in sizes 18,19&21.

I think the needle that came with the machine is correct because it has Simanco 18 written on it. I measured the needle diameter and its 0.8 mm. However, this does not match the singer conversion table which says size 18 should be 110 nm.

Anyway I do have a packet of 215x15 needles and the shank diameter is correct at 1.0 mm, the distance to the hole is 27.9mm. Interestingly this is the same distance as the Bonis 292 for the older machines (canu 01:30ma), aka ns292. This is also the same length as for 46x5 singer system, which is for some 46k fur machines and I bought hoping it would fit.

Does anyone know an alternative to 215x5 system?

A table of Singer 46k overseamers and their recommended needle size. The numbers I give of those that I have measured. There will be some error in these.

machine needle system length to hole shank diameter total length

K15 46x3

K30 46x5

K37 215x9 or 88x1

K38 215x13

K39 46x5 27.9 mm 0.96 mm 34mm

K45 215x5 30.0 mm 1.08 mm

K46 215x15 27.9 mm 0.98 mm 32.4

K48 215x17

K50, K51 16x21

K52 215x21

K54 46x5

Cheers

Someone may have adjusted the machine for a different needle, And perhaps you could do the same. I know nothing about your machine, however this is done in some old machines.

If you can find a needle with the right shank but is a little too long, you may be able to grind/file a bit off the end to get it to seat into your needle bar further and align the eye properly. Just go slow so as to not overheat the needle and ruin temper. If you can't touch it it is too hot, put it in water for a second or two.

Messing with sewing machines has not been very successful for me so it will be the last thing that I do. :(:)

I like the idea grinding the needle down. The problem is finding a long version of a needle with 1 mm diameter.

Is there a website where I can search needle systems on diameter?

Thanks

There has to be a simple means of loosening the needle bar and repositioning it for the needles you are able to obtain.

My current crop of sewing machines:

Cowboy CB4500, Singer 107w3, Singer 139w109, Singer 168G101, Singer 29k71, Singer 31-15, Singer 111w103, Singer 211G156, Adler 30-7 on power stand, Techsew 2700, Fortuna power skiver and a Pfaff 4 thread 2 needle serger.

I'll take a look at my big reference book of everything Singer tommorow and see what I can come up with.

Thank you very much, Everyone... I wait in hope... :)

However, I cannot even find another sewing machine that uses that particular system. Its extraordinary that they would produce another needle for just one machine.

It might be important to mention that the official parts list describes the machine as "for home manufacturing." However, to me, it does not seem like a domestic machine. It is infact the largest of my overseaming machines including the Strobel fine fur sewing machine (0.5-2.7 spi). It is further described as "for seaming hoisery with selvedge edge."

Apart from the hand rotated wheel it looks exactly like 46k24 mentioned above and this is for medium weight fur. But the recommended needle for that is 3.5 mm too long.

To give you some idea of what it can do and thus its robustness I have measured the spi. I can go from 14.5 spi (1.5 mm stitch length) This seems very robust for sewing underwear (Hoisery?)

to 7.5 spi( 4mm stitch length).

Thank you for your time and help. Enjoy what is left of the weekend.

Alex
