Handcrank sewing machine

Threaded View
I have to sew a large number of straps/handles onto canvas, straps being
canvas themselves and sometimes light leather. Sewing construction will
be typical "X" inside a box. Box ax. 1 1/4" on a side.

Having a little trouble controlling my machine, sewing slowly enough but
with power. I'm thinking of converting an old Singer Spartan to hand
crank, three stitches for 1 revolution of the crank.

I don't have the option of trying this out on an existing machine.
Anyone have any experience with handcranking as far a gaining some power
and slowing things down for more control vs, a regular machine like
Pfaff 130 or Singer 201?  Is this hand crank a step in the right direction?

Any help appreciated, thanks.

Re: Handcrank sewing machine
I've got a Singer 99 I converted to a handcrank.  It certainly gives
you more control vrs a motored machine.  It does not seem to give me
any more power, though, than any of my other vintage machines....I
also found my hand gets tired after a while (I mainly use it to piece
quilt blocks or sew seams) and would likely happen moreso if I were
sewing heavy/thick stuff.

My experience with my handcrank machine is that it would not be better,
although a treadle would.

You might want to see if you can find an old Sailrite sewing machine for
cheap.  It would do the job nicely and is made for heavy-duty home use.

I seem to recall there being something called a ?power wheel?
which was an oversized spoked hand wheel.

This ?power wheel? replaced the standard hand crank wheel on the
sewing machine and was a larger diameter,  like say from 5"
standard to a 7-9" oversized hand wheel/pully and it slowed the
machine down but could allow one to give a little more
power/torque ?

I thought i remembered seeing them on ebay and my failing memory
recalls that someone was manufacturing (lathing) them for some
vintage  singers and pfaffs and such

I did try to search based on my memory and the closest similar
thing i could find was this example but this is only for sailrite
but it is a similar idea ...

Industrial treadles have larger balance wheels, not handwheels.  They
are more powerful.  Look at a Singer 31-15 treadle to see the
difference.  Some people report getting a lot of power from their Singer
15 treadles, and their Singer 201 treadles (hard to find) but the
industrial 31-15 beats them both.

I've used both my Singer 66 and a 28 for this sort of operation, both
hand cranked.  It works very well.  Remember to use a leather needle for
the leather and a large JEANS needle for the canvas straps.
Topstitching/upholstery thread might also be a good move...

Many thanks to you and others who also gave excellent advice. I'm
looking into having a large, heavy handwheel made for my Spartan,
because standard handcranks have a 3:1 speed gear-up and I want to go as
slow as possible,1:1. I'd just be giving up the bobbin winding function,
but that's no problem.

Do report back, Bill. I'm curious as to how it goes.

That might just work.

I didn't bother with a bigger handwheel, it wasn't necessary.  If the
needle wouldn't go through a particularly thick bit, I juste wrapped the
handle in a bit of spare cloth and tapped it gently with the hammer
until it did.  Did the job and did no harm to my Spinning Jenny Singer
66K back in 1974...

See!  There really ARE engineer genes in me!  ;)
