This project aims to design and build a scrollsaw based on a sewing machine.
For months I had an old sewing machine standing in the corner of my workshop, not really knowing what to do with it. It had been thrown out by the previous owner because it didn't really work anymore. The most important components, however, still functioned. I hoped I would be able to fix it.
But, whilst taking a closer look at it the other day, I figured out two issues about it: - I couldn't find the sources of its many problems. - I actually don't need a sewing machine. A scrollsaw, on the other hand, was something I could find use in.
All materials used in this project are extracted from the sewing machine or is scrap wood.
I don't suppose you do have the exact same sewing machine, so I'll be a bit more general with the instructions: no measurements or dimensions. Not that there ever were any..
Let's start out with disassembling the machine. I'll remove all components, I wouldn't need. It is important not to destroy any of the components, since they might come in handy later on. So put away you saws and hammers, and get on about this with screwdrivers and time.
I was surprised about the inside. This thing is like a clockwork! And build to survive an atomic attack. Everything is shiny stainless steel or molded aluminium - rarely plastic. Thanks to the rather modular design of the machine, it will be rather easy to disassemble the parts not needed, which is like 90% and quite allot.
The mechanism for the needle will stay, as well as the drive shaft and the motor. The presser foot and its lifting mechanism will later be used for the other end of the cutting blade.
