Slowing A Consew 206Rb-3

[georgeandgracie]

Now that I have this Consew, I can tell that I would be happier if it ran slower. It's not bad, but still a bit lively. I can't just turn the wheel by hand for finicky stitching - it's too stiff.

What are the options?

Options

A. Learn how to feather the foot pedal

B. Put something under the foot pedal so it would not travel into high speed. example piece of dense foam

C. Put on the smallest pulley available on the motor shaft, you would also have to buy a shorter belt

D. This is the best option available and it will change the speed of the machine drastically. Invest in a servo motor, cost around $100.00, it will mount in the same holes as the original motor. You could adjust the speed to a crawl. I hope other members will respond as to what servo motors they have found to be best.

Add a cobra speed reducer and servo motor

and BE VERY happy with the end results...imho

If you press on the pedal a little, it releases the motor brake so you can hand wheel it easier.

If you are sewing heavy leather, even with a servo motor, you may need either gear or pulley speed reduction to help punch through the leather at slow speeds.

Here's a couple pics for those that like diy projects. This is a speed reducer I built from stuff laying around the shop. I needed it for a Singer 300W chainstitch machine to sew through up to 6 layers of 4oz suede for welding jackets. I've used variations of reducers over the years for specific tasks. At some point, I'll remove it and use it on another machine as needed. If anyone's interested, I'll post a more detailed description on building a speed reducer.

I also equipped this machine with needle coolers and silicone thread lubricators for both the needle threads and looper threads. This allows for sewing longer seams without thread breakage from heat, but that's for a different thread.(<pun)

That's awesome! I love the staple in the V belt from the motor to the reducer, use what ya got handy!

I buy that belting in big spools. It's nice because if I need an odd belt size, I just make it. What you can't see is that on the inside of the belt is a grove that the connector sits in so it doesn't go "click-click" with every rotation. I use the same connectors for the 5/16" round leather belts I still use as well. I do have polyethelyne round belting, but I actually prefer the leather.

Shoes off, easy on the pedal and use your right hand on the fly wheel to as breaks.

Here is a home made reducer one of our member made (pic one). If I have a machine with three phase motor who needs to be slowed down I use a frequency controller, it gives you full controller of the motors speed and many other parameters too. You can run it at one stitch a minute if you like. And it converts the motor in too a single phase so you can use it on the regular household current. Here is one.

I broke down and bought a servo motor. With its knob set at or near the slowest position, I am MUCH happier.
