How a sewing machine works

When I was in junior high my Mom would toss my jeans when they got tears in them. of course, that was just when they would be 'worn-in' just right. One day I asked her to sew a patch on my jeans and she replied, 'No...I don't want you to be seen in public with my patches on your jeans. But...you can sew them on yourself.' She confided to me, years later, that she said that thinking that I would just let the idea go. That explained the look on her face when I said, 'OK...will you teach me to sew?' Of course, now she was trapped :) she taught me the basics and I've been able to mend, patch and make things since.

How the bobbin works has always been a mystery to me. Not anymore. here's a cool gif of how a stitch is made:

Cool GIF. I remember in Navy boot camp we laughed at the couple guys that got orders for Parachute Riggers school. Little did we know at the time...

"I still wonder why they can’t make a machine that will take another spool of thread, thread it around so one can use that instead of having to wind bobbin after bobbin….."

Above was from the site.

Answer is that to place a spool of thread in the bobbin would create such a large size that the thread would heat up and break.
The thread goes back and forth through the eye of the needle around 70 times to form a typical 300 class stitch with the current sized bobbins.
Any increase in the bobbin size means hundreds and perhaps thousands of times a given spot on the thread would have to pass back and forth through the eye of the needle.

I just bought three more inductrial machines.
A walking foot single needle,
A 90 degree corner turning - full oil bath - double needle
A bar tacker.

Machines are in new condition (New cost $ 9,800) and I got about $4,000 worth of materials too.

This to go with my WWII Singer double needle plus stuff.

I was a master rigger. Nobody gets to come by and use them.
 
People break things.

People who climb trees to cut them into pieces are not finese talents who care about my machines that I've dreamed of having for so many years.


Brouhaaahhaaaaaaa.

=============

Two of the machines I can fix myself anytime. (Still not available for human beings)
The bar tacker is a different story. I won't even let myself use that one.
 
Today I put a new power cord and foot pedal cord on my Pfaff 332. As near as I can figure the machine was built in the early fifties. The cord looked like a factory setup since the ends of the wires were tinned [covered in solder] and the cords had strain relief wrapping on them. Not bad service for 50 years...whew....
 
Brouhaaahhaaaaaaa.

Master rigger refers to parachutes and related items like harnesses.

I'll be going into business making fireline gear over the next two years.

For me these machines are not an air compressor to be lent out.
