Singer 51 W 25 Stitch length?

[Irishleather]

Ya, that spring didn'y work. lol  I look for a picture on a parts list. Hopefully.

I don't think it's all there, judging from the list of parts and pictures.  There is a round piece between the plates that looks like it is for part of the spring to move on.  I need to just try some things, even something semi-modern.

I'm comfortable with changing needle bars and readjusting the timimg. Why not just raise the bar for a longer needle? I have a lot of different needles for somewhat old sergers and just old unwanted stock from a boot maker in Eastern WA.  I will choose the needle (sort of) for the reasons you did and maybe only need to raise the bar. 

The 128 needles for this machine have a smaller shaft diameter (1.75mm IIRC) but maybe someone already changed the needle bar before and you can use 2mm shaft needles. Just try it.

The needles from your Singer 17 may work. The Singer 17 is using 16x231 (and similar) needles which have a 1.62mm shaft thats why they may fit. But due to the different shaft diameter the needle is a little bit further away from the hook tip so that could cause problems with catching the thread loop.

My intention was the use of 2mm shaft needles. Thats why I changed the needle bar. If you buy a new needle bar then keep in mind that I have drilled the casting and installed a longer top bushing to guide the shorter needle bar I have used. I have not found a longer needle bar. Not saying there is none but I have found none.

Regarding tension disks - you can use tension discs from a Singer 107w or 111w they have the cutout for the stop pin too. You need two of them part number is #244048. The 3rd disc you need is the tension release washer with the small tab across the center hole. Part number is 204271 (lower left corner in your picture).

Saturday morning on my side of the pond... raining again... so I did some more research

I found a complete tension unit that most likely fit your machine cause it is for the Singer 12w which is W&W based as well:

And therefore this check spring should work for you as well:

I also figured the parts number for the bobbin case tension spring:

How have I figured this - well there is a 51w100 post bed machine and it is the old style 51w and it has a parts list... Bobbin case is the same as on my 51w so I would guess the other parts are the same as well so I googled the numbers and found the parts on Ebay.

All to my best knowledge - cross check if you want.

Thank you so much!! I appreciate your time on this. Going to look now that the rain have driven me inside.

You are welcome. Its interesting fro me too to figure where to get bits for upcoming projects. Always good to have cross references especially for these very old machines. Fortunately Singer continued using certain parts so the chances are good to find even some of the "odd parts".

Keep us posted with the restoration progress of your machine.

I was looking at Wheeler & Wilson nose parts and I think those lower tensions with the take-up spring might work. The passive tension up high doesn't worry me. It's the lower tension because it is missing parts.  I have a bin full of old new stock springs and recovered tension parts. I'm grateful you found the case/cap tension spring. I will order those. Then Frankenstein the lower tension until a Wilson Wheeler or other complete tension with take-up spring (with or without the actual spring) shows up. There were a few on eBay, but already sold. I have a friend that collects then, so I'll be able to really see if that is an option. I'm excited it will take longer stitches when I get the parts.
