post an image of the area of the hook, where the thread is shown and discussed in the video above. Is it a Simanco hook? just curious.tyvm

quote--(I was hoping someone could help me with adjusting the presser foot knee lift. Whenever I do it, the rod on the machine seems to want to twist, and then all of a sudden it "lets go", and makes a spring type noise. From the videos I've watched, the action is suppose to be smooth. Also, could someone explain how to adjust the spring that is on the rod itself with the set screw? Not sure where to set it exactly.)

The end of the lifting rod under the machine needs a smooth rounded surface, like a small wheel, or in my case a small heim joint that I repurposed.

s-l1000.jpgI just slid the end over the lifting rod, with a thin piece of foam rubber wrapped around the rod to prevent it from falling off. You could thread the rod if it was the right size, mine was not. The round surface will provide a better smoother action where it touches the metal pad  when you use the knee lift.

 

Great idea, thanks!

Thanks to DSloop's idea, and seeing pics of the Consew 226B lift arm which has a similar bearing on the end, my dad and I decided to make our own. I included some pics of the machining process for those interested. Seems to work well.

What is this for?

I believe it is a presser foot knee lift roller, but I could have misread the description.

Looks like it. Never seen anything like that, some installed pics would be nice

It depends on the foot lift mechanism, some are push types, some are pull types and and some have a kind of bell crank lever installed on the underside of the flt bed where the roller pushes against (like my 307G2 Singer)

So sometimes knee lifters come with a roller installed or a roller is installed on end of the lifter rod on the machine  - they look like this.
