Singer 45K - Skipping Stitches

[Cobra Steve]

Hi monkfinck. Have you checked the needle bar height? If you need a new shuttle hook, or race assembly one of us sewing machine dealers can get it for you. Let me know. Steve

Chris,

I'll have to agree w/Anne Bonny,I just checked the hook ring from our Cowboy 2500 in a 45K25 & it looks like it might fit with alittle grinding were the pins mount.

Let me know if your still need one.

I reversed the retainer ring, tried adding thinner shims, raised and lowered the needle bar dozens of times, tried different sized needles.

When I hand crank the wheel everything appears fine - the hook finds the loop and completes the lock stitch. When I start sewing leather it stitches ok on a straight pass, but when I drop the needle and turn 90 degrees then commence stitching, after two or so stitches... a skipped stitch.

I think the 45K is tired. I know I am tired! My business depends on a reliable machine, so after doing my homework, I called Steve Tayrien and purchased a Cobra Class 4 package w/ the accessories. http://www.leathermachineco.com/catalog.php?item=57

As most of you already know, Steve is extremely helpful and passionate about his Cobra machines. Initially, I was tempted to go for an Adler 205, but numerous sources told me Adler is now making this machine in China and I could not personally justify paying double the money vs. the Cobra (Juki 441 clone). Juki parts are also reasonably priced in comparison to Adler.

The Cobra should be delivered late next week. Thanks to everyone who tried to help me resuscitate my 45K. I still love my other vintage machines, but I am curious to see how a brand new machine handles in my shop.

if anyone is still interested in replacing the shuttle ring in a singer 45K i just replaced the hook/shuttle ring in a 45k-25 part number 91430 with a shuttle ring out of a Typical TW3-441 part number: 52WF1-032, drop in replacement, no grinding or modification required only difference is the original singer shuttle ring is 3.30mm thick the typical one is 3.50mm thick.

I have no need for a replacement but this is a good hint! I always wondered if parts from new machines could fit the old Singer 45K and Adler Class 4 & 5. At least worth checking it out when someone is in need of replacement parts. I´m sure a lot more parts will fit but for sure depends on the machine.

Great bit of info to keep the old Singers working, and not turning into doorstops, or lampstands (worse upcycle seen on ebay, ever).

parts from the typical tw1-2b can be used on a 132k6, feed dog, needle plate, main tension assembly, needle bar, the same needle bar with clamp will also fit an adler 105-64 at a fraction of the adler price.
