Members Historicalbeltworks Posted August 29, 2023 Members Report Posted August 29, 2023 I need to change the hand wheel to a larger one, I’m starting to get a blister from cranking it for the right needle position :), it’s just too small. Can someone point me in the right direction to get a new larger wheel or one with a handle? Thanks. Quote

Is there a brake in your servo motor that is making it difficult to handwheel? If so, disable the brake. You can test by removing the belt to see if it is easier to turn. Quote

Members Wepster Posted August 30, 2023 Members Report Posted August 30, 2023 In lieu of replacing wheel, could you drill, bolt on a small bracket and add a knob, like a steering wheel knob? (I grew up calling them necker knobs). Quote

Members dikman Posted August 30, 2023 Members Report Posted August 30, 2023 The chances of finding a large replacement handwheel would be very slim, it's not something that was commonly offered as an option. Some people (me!) have replaced the handwheel on a sewing machine with a large pulley, the main reason being to slow the machine down but it would also help with hand-wheeling.

Members shoepatcher Posted August 31, 2023 Members Report Posted August 31, 2023 Why replace the wheel? You want to slow the machine down? A servo motor will do that. I have a 669 with a servo motor and a 45mm pulley on the motor. You could add a speed reducer to slow it down more. However, with the speed reducer, you cannot add a synchronizer to the balance wheel because it screw up the sensors in the needle positioner part of the synchronizer. My runs as slow as I want it to. I also got a 669 from weaver. it is an Eco model. I added air foot lift to it. glenn Quote

You can start by removing your existing balance wheel and measuring the diameter of the shaft. Note if it uses a key to position the wheel. Then measure the diameter of the wheel and search online, or contact Adler or Weaver to see if they sell a larger balance wheel as an upgrade. If the shaft diameter is more or less standard, you might find a larger wheel for a Consew or Juki.
