Hello last resort of the free internet.

I had to sew some stoff for my basement and realized it is a real (marksmen?-)ship. It is more complicated then cutting wood for some furniture.

Anyhow, I want to enlarge my machine’s sewing step. That is, I want it to be able to sew more than five milimeters with one step. Maybe I should add a motor with more then 90 W (current Motor), but can this archived with gearing?

I do not care for sewing steps beyond <2 mm. Though my clutch allows any step-width fluidly. I am capable of deconstruct the machine and weld anything to it what is required. And make it in weight.

But my issue is figuring out what change would enlarge the step-width.

Even if your suggestion would change my settings, let me know your idea please.

Some pictures of the Internals:

(when issuing my hand down, the gearing enlarges into the direction of the arrow. But there is a ?Bobbing? on the left side. Imo this should be dependend on a rotation so I can enlarge the leverage nonetheless)

I would appreciate any tip!

I try to be in the middle of my own opinion and beeing inclusive. Sorry for stepping ppl on the toes!

    I understand you know how to change the step length that can be changed now, yes?

    Yea

    You say <2mm to 5mm. My very similar machine can go to almost 10mm but it cannot keep the thread very tight.

    I would die for 10 mm. I would be in to adjust the machine while sewing for any step lenght larger then 5 but 10 mm would be perfect.

    This is the limiting thing, the machine, every part, is designed for sewing a length of 2-8mm or whatever. A longer stitch step would need a complete change and probably a stronger motor.

    I can change gearings, leverages and axles if I understand what to communicate. I am not bound to the current chassis and motor. I can construct a chassis afterwards rezpecting current alignments within nm.

    By moving the knob or lever that changes the stitch step length, you will see what is going on.

    I circled the change in blue. Leveraging the handle could be the case but axles wind on their own. It is a mind fuc* which can only be put in perspective by Engineers, imo.

      I am not an engineer, either 🤔 I see your front picture, my machine is similar. I would not be able to change anything myself. As @[email protected] mentioned, these really are highly engineered. If you change one thing, you must change everything.
