A few years ago i bought this tent-like-material when i was making a new seat for my motorcycle. The other day i wanted to make a strong, waterproof, lightweight backpack that can be folded up and put in your pocket and figured that the material i had would be perfect. There's lots of instructions online on how to make the string backpacks. It seemed pretty simple.
I tried to sew it by hand but it wasn't near strong enough. So i went to the Salvation Army and bought a sewing machine for $30. I plugged it in at the store, pushed the pedal and it seemed to work, the needle went up and down... When i got home i tried using it but it didn't work. The thread kept getting jammed. Charlie also looked confused by it.
It took me a while to figure out how it worked. I read about the machine and saw that online they sell new for $150.
I figured out that the mechanism that spins the spool below the needle was slipping. The round thing at the bottom is what holds the thread.
The needle moved but the thread wasn't catching. So i had to open up the back panels and tighten the two small hex nuts that attach to the spool axle. It was a lot more complicated inside than i thought.
This is where i aligned everything and then tightened the gear to the drive shaft. Both of those black hex bolts were loose.
Once it started working the thing was great. It has settings A - P. For the bags decided on L, a kind of square shaped pattern.
I always said that a sewing machine worked just like a scroll saw.
Here's all the parts for the backpack.
This is the corner with the grommet and the reinforcing.
Finished backpack.
