However I wonder if you could replace the handwheel with a spoked one, and then get a hand crank for it. I think you would have to wind bobbins ahead of time since the bobbin winder rides on the handwheel. Another option for the FW might be cutting a notch in the wheel for the crank. I've never done any of these things but I've seen them posted on the board. I think it might be Steve H who notches out wheels. I think I also saw a tutorial about it on treadle on.

One revolution per crank isn't the end of the earth if you aren't doing production sewing. You can use a sidewinder to wind bobbins or like mentioned, wind a bunch ahead of time.

I would take this... (and I do)

I haven't figure out how to HC Cinderella. She is light and small. Her motor boss doesn't line up and it is too short of a distance. Her hand wheel is smaller than usual so I can't borrow one off something else to fit on her.

This is an interesting hand crank mechanism. Makes you wonder if something could be mounted the base of a case instead of directly to the machine. |

you can just drill and mount a handle but the handcrank give 3:1 ratio of cranks to stitches. BIG difference is work load and the 3:1 provides additional torque.
For situations like Miriam and the munchkin sewing sessions 1:1 is good, but I prefer the ratioed handcranks for sure Steve |
:)I use the hand crank referenced for boat cover repairs in situ. I concede the 1:1 would get tiresome for what most machines are used for. 1:1 with a largest hand wheel or extension to max diameter permitted would give enough torque for minor use. My rotator cuff would suffer, however.:)
Edit: I see Miriam has answered the 1:1 concern more succinctly than I in post #12. |

My Sailrite Ultrafeed clone has the monster hand wheel, like pictured below, with a handle attached. I've wondered why a person couldn't tap and thread a handle on most any solid hand wheel. When time permits maybe my 301a...... I might try practicing on my sledge hammered T&S first.:D
http://www.sailrite.com/604U_1_display.jpg THAT machine turns easily enough - might make a good 1:1... :cool: |
