How to Slow Down a Sewing Machine Running too Fast - Singer Heavy Duty Speed Control

Hi Granny Wheels, I have a singer 834 and the foot pedal has a carbon disk rheostat, not a circuit board that you show. One terminal has a long flat plate type connector and the other a regular female connector. Can this setup be modified with yours?

@grannywheels did you know that you can dial down the potentiometer top left in the foot pedal to slow it down as well ?

My sewing machine has the same pedal, however I opened it and the machine won’t start near the high end/the start of the slider: it would only start running when the slider reaches near the lower end. I would say only the lower 25% length of the slider actually starts the machine, that gives very little room to control the speed.
Any idea why would this be like that? Can it be fixed? I see a potentiometer there inside the pedal, could turning it help on this?

In the video, you said that the power of the machine does not allow you to sew leather at very low speed. If you don't use the pedal but use the wheel by hand, can it go through the leather? (like you do for the corners). I ask this because I was wondering if it was possible with any sewing machine to freely hand sew stitch by stitch (and disabling the feeding tooth) so that I could do some sort of hand embroidery?

Thank you for your interesting and informative video. With your modification does the footpedal now merely act as an on/off switch and the speed is entirely governed by the slider?
Or does the slider set the maximum speed when the pedal is fully down but it can be made to run slower with lighter pressure. I.e the slider acts as a maximum speed limiter.

Hello. A question . If you have a sewing material, thick, say 8mm-10mm, can you sew it with this machine? And let him say, you want to mow in zigzag, or other patterns. Can you do that with this sewing machine? I ask out of curiosity. Thank you

What model is your singer? Is it a 4452? Also on the label on the back does it say it was made in Taiwan or Vietnam?

thank you for this fine trick👍🌟🌟🌟🌟🌟

You have an idea How to mount an external binder to this Singer Heavy Duty machine??

Where did you get the second foot pedal $

Most ingenious! Thanks for showing this modifications

I bought a Granny Wheel.
It's a great addition and seems to smooth out the action on the foot pedal.
