The cheap way to slow down an industrial sewing machine that nobody talks about!

The smartest strategy for slowing down an industrial sewing machine for sewing leather or heavy assemblies! In the video I show you a Consew 206RB and a Consew 146RB, but this idea applies to almost any sewing machine. Get a small pulley on your motor, and replace your hand wheel with a big pulley! For those confused about why you wouldn't just limit the motor's top speed, or adjust the limit of travel on the speed control of the motor: This limits the machine's top speed, but you will lose your fine control of the speed. Imagine two powerful cars that are fixed in first gear: Car #1 has a brick under the gas pedal. You can move the gas pedal a quarter inch, and the car will quickly go 20mph. When you want to go 10mph, you can't find a position for the pedal that represents 10mph, instead, you chop at the pedal on and off to average 10mph. Car #2 doesn't have a brick under the gas pedal. The gear ratio has changed, so the car's top speed in first gear is 20mph with the gas pedal fully depressed. You can use the full travel of the gas pedal, and it's easy to tell where 10mph is and hold that speed. You're approaching a school zone full of kids, there's a police officer at the side of the road, and the speed limit is 10mph. Which car would you rather be driving? ---------------------------- High quality cast iron Martin sheaves (pulleys) - There is wide variance in price based on outside diameter; be sure to check similar sizes: http://amzn.to/2hkDhNU Consew CSM1000 Servo Motor: http://amzn.to/2xS98QS Consew CSM1001 Servo Motor (Same as above with needle positioner): http://amzn.to/2wIgMrO Cheap calipers for measuring shaft: http://amzn.to/2jNafuQ Inexpensive drill bits available in odd sizes: http://amzn.to/2xoIjlu More pulley options: https://www.mcmaster.com/#v-belt-pull... eBay Consew CSM1000 50mm pulley: http://www.ebay.com/itm/Consew-SM550-...
