I started a new project recently. I found an part off an old sewing machine at a local thrift store, added some pieces aluminum, mix in a little imagination, and we will see if it does anything fun.
If it works it will be single acting oscillating, "steam" type engine. If it doesn't work, then it will be a nice addition to my paper weight collection.
The last project barely worked at all it was meant to be a wooden motor powered by a vacuum cleaner. My son had fun with it.
