Singer 45K25 Dos'nt Like Linen Thread?

[Trox]

The shuttle you can use are made by Japanese Hirose, Italian Cereliani and in by the Chinese. As Darren said you can use the DD1 closed type or the open type DD1 OP2 (same type as you have). https://www.college-sewing.co.uk/Singer45KSewingMachineParts

I do not know if its necessary to change yours, its hard to tell by the picture.

One thing, what kind of oil are you using in your lube pot? Regular oil will make your thread stick to the metal and it will not make thread loops. I hope you have tried it without oil?, its maybe a stupid question. Nevertheless, I have tried regular leather oil and it did not work, my machine skipped stitches all the time because the thread sticked to the metal.

Try using liquid silicon lube, which is sold in quart bottles by most industrial sewing machine dealers.

Thanks Trox and Wiz,

Actually I did not try it without oil! I have white sewing oil in the pot.

I wonder?? but, it seems to be fine now that I put the nylon in so I'm not freaking out that much anymore, but I might give it a shot dry.

Oil is not thread lube. The best I have found is from Puritan, Ceroxylon wax. Lubes the thread great then dries &sets and seals the stitches.I first thought $65 a gallon was high but after useing it worth it to me. don't gum things up.

You cannot use Oil.

No wonder it will not sew if you use white sewing machine oil, the thread will stick to the metal and be unable to form a loop; the result is skipping stitches. You must use thread lube like PCOX told you above, thats not oil.

On polyester and bonded nylon you can use silicone thread lube too cool the needle.

These old machine was built when most used linen thread and it is the best thing you can feed them. Does it use the 328 needle system or a similar Singer system, I believe they use a shorter needle than the 441 machines do (794); they do not create that much heat. Thread lube might not be necessary with polyester, you can also use prelubed thread.

You must also remember that sewing machine thread is fresh ware, you cannot take any old thread and expect it to work well. It dries out and becomes full of dust particles when it is stored unprotected. You can spray old thread cones with Fibings liquid glycerin saddle soap, it will restore some of its moister.

Good luck

Which machines do you use Ceroxylon with?

[pcox]

Wiz I use it in the puritan high speed , singer 29 patcher, and when we make bio harness the Landis# 1 and cb4500. I think it really helps the thread pull up in the bio, takes less tension to set the stitch. I think it would be great in the 45x25. I like the purtian setup where the wax pot is after the tenison disk

Does Ceroxylon gum up the tensioners, guides, or needle's eye? Is it water soluble if it thickens in the pot?

[pcox]

I have not had any of those problems with it. It will dry on the thread down the thread path from the pot if it sets over night making the thread stiff. I just pull that thread out of the needle till I get fresh lube to the needle. I have not had it thicken in the pot yet so I haven't tried to thin it but I think it is water soluble as it washes off my hands easily with plain water. there # 1-860-693-0791 or

A couple of 45's I've played with have a small problem with the tension assembly.

Keep in mind that the 45k tension is completely different to most other machines in that the thread is wrapped around the tension wheel which spins to feed the thread and the tension spring retards the motion of the wheel. Pull the tension apart, polish all of the mating surfaces with ultra fine steel wool and then apply a light coat of oil before reassembling.
