Because I have no other choice! She's the size of a 15 and I don't have room for a treadle. I'm also missing the special bracket that helps mount them on a table top. They aren't that common round here so i don't want to drill and tap for a bolt, and I'd need to buy the motor boss bit (which are available but expensive)
I am also just a teensy bit of a masochist

That helps a lot Macybaby, thank you

Oh, I get why to make it a handcrank, it is just that the 3:1 that you get from an actual handcrank makes it SO much easier to sew with.

So that machine has the spoked wheel, (which the regular handcrank would connect to to operate) but no motor boss.

There are a couple of options I see.

One is you could make it a portable electric. If it is a 15 base, then a case would fit. Making a bracket to mount the motor to the case not the machine would not be too difficult

The other option is that some makes of machines used bed or base mounted handcranks. one of those might be able to fit

the last is the wheel spinner. You may have to buy them online. they are not legal on cars in several states so not many parts stores do not carry them (at least around here that is)

Thanks Steve!

I'm not sure about the exact size, i'll have to measure the pins and the base. There was a bracket that was supposed to be part of the machine that helped it to bolt into a table but i might not need it I do have a spare motor hanging around, so i wonder how that could work! Getting the bases here is tricky, might have to buy a trashed machine and part it out

I have seen some of those for sale, i don't know how to calculate what measurements need to fit for it to work, any ideas?

They are legal here in Australia afaik, sold in tractor parts shops and also as mobility aids for driving cars

I'm starting to thinkt his might just work! Trying to source some 128x4 needles from the local industrial machine shop.

Very cool looking machine! What does that machine do? I walked into NAPA and asked for a steering wheel spinner or a suicide knob. They said those were illegal for a car. So I told them I wanted to put it on my sewing machine and they found one but told me to ask for a tractor steering wheel spinner knob. Tractor supply also has them. BUT I saw one I thought I would mention. Someone welded an auger handle onto the clutch knob of an old industrial - the guy was sewing alligator hides with a treadle but he wanted the option of hand cranking it to get more torque. The advantage is you could remove the clutch knob and put another one on it.

I had an old industrial that size and it just had a little motor added onto it on the back. It was kind of portable... There are any number of ways to add a motor. You could just build a wooden frame to set it in. In fact you might mount a motor to The frame. Is that some kind of pin tuck machine? It would take for ever to do much by HC with that...

It sews 5 rows of chain stitch, it will do shirring if you hold your tongue right, and that's what I'm hoping to do! It will also do pin tucks with a special foot but I don't have one.

I also think I've got the needle size wrong!

I saw someone doing that with featherweights, welding a window crank to the clutch knob. I've measured and it turns out my hand crank won't fit because the finger isn't long enough, the spoked wheel is pretty far back and protrudes in the middle which gets in the way, so my current plan is buying a base, and making a bracket that will hold a motor. The base of the machine will fit a standard singer base lengthwise but its narrower than my 99! Will have to put some scrap wood in the base to prop up the front of the machine

miriam

Wow. Sundresses? A good wood worker could get you set up pretty nicely with a base. A HC would be handy if you wanted to set up at some festivals or craft sales...
What I saw was not the same thin as the window wonder winder guy. It was the handle from an auger - think hefty. It was welded right across the clutch knob. The clutch knob and its handle. could be removed and it could go back to normal.

miriam

are those FW clutch knobs welded or do they just have a tapped hole to screw the window winder?
