I have a Singer 15-90 treadle. I have been using it for sewing some double or triple folded cotton fabric. I am making fabric bins. Sometimes I use the hand wheel to go through rough spots of folded fabric. I am worried that I may catch my fingers in the spokes. I have a spinner but it does not fit the hand wheel.

I was wondering if there is a way to use something similar to a spinner or HC and still keep my SM as a treadle? This way I would not feel concern about catching my fingers.

Thanks.

Hey Kathy, if you don't have a solid balance wheel (which is sounds like since you are concerned about finger-grabs), then you don't have a 15-90.  It sounds like you have a 15-88.

Yes, you can put a hand crank on it.  One of the modern reproduction ones will work well enough or you can get an original one at half the price of Ebay sellers from Helen Howes here:  http://www.helenhowes-sewingmachines.co.uk/cranks.html

You can keep it disengaged most of the time so you aren't driving the gears on the hand crank as well as sewing while you are treadling, then clip the catch for the spokes in place when ready to hand crank.

Hi David,
I took the motor off my 15-90 to convert it to a treadle.
I don’t understand what you mean by “solid balance wheel”?
Thanks,

Here's what the two versions are.  If you had the motor and the wheel on then left then you probably have a 15-88-89 someone upgraded with a motor later.

In most cases you need a spoked hand wheel to fit a hand crank, it's larger than the small solid cast wheels. There are a few exceptions for the very late cast iron and aluminum machines (like the green and beige models), but the hand wheel is still especially shaped to fit a hand crank, most beige 201s and 185s machines didn't have it.

Hi David,

I do have a spoked wheel, like the one you show on the left picture on my Singer 15-90. I have put a reproduction HC on my Singer 66 that was originally a treadle. This treadle is the one I am using for the 15-90.
I will try the reproduction HC on the Singer 15-90 to try it out and see if it is feasible.
thanks,

Even using a hand crank machine I sometimes switch to pulling on the wheel directly when the going gets tough.

Note that when you press on the crank you'll only apply a third or a quarter as much force to the wheel, as compared to pulling on the wheel directly.  You also don't have as fine control.  That's because of the gear ratio of the crank, which sews 3 or 4 stitches per crank revolution, instead of 1 stitch per wheel revolution.  Plus, you will be applying that force in the opposite direction:  when the crank is closest to you you'll be pushing up, rather than pulling down, as on the wheel.

Just something to think about.
