I think a hand crank would be a great thing for my kids to practice on. Especially the 6 year old who really wants to sew but I'm still a little scared to let use the big machines.

After i vaccinated myself, my mom made me use the FW - actually it was easier

Looking at my WFR in the crinkle finish with a motor, it doesn't look like there is any place to attach a hand crank. These do still have a spoked wheel, but I'm not sure how you'd retrofit a hand crank to it. The motor attaches to the back of the machine with screws. There is nothing like a "motor boss" as on the ends of most Singer machines.

The only one I've seen is here: White FR hand crank pic.

I read somewhere (can't remember where) that White's were sold in the US, so not as many were made with hand cranks, mostly treadles and motorized versions.

I have several that will not hand crank. I have a Cinderella, 319, 306 that the motor boss does not line up with the wheel so that it will turn properly. I have some old machines with no motor boss and some with a motor that attaches on the back of the machine. These will not HC. There are newer machines that will HC and newer machines that won't because they don't have a motor boss. Some machines that will not HC will treadle. Go figure.

So, Pumpkin Patch, did you get the White Rotary with the crinkle finish? (I've got one in my garage...)
