One day, I aspire to experiment with constructing a miniature gas turbine (jet engine). A task like this represents some of the most challenging machining work achievable. Their similarities to machine spindles, another intricate machining project, lie in the necessity for precise and robust bearings due to them constantly rotating. However, they present even more challenges as they rotate at incredibly high speeds and are subjected to excessive heat.
There are shortcuts available, however. Rather than build a turbine from scratch, one can adapt a turbocharger from a car or truck to the application. The high heat/high rpm rotating assembly is then already taken care of. Still not an easy project, but much more doable. If nothing else, these monsters are impressive to watch. Here are a couple videos for your entertainment:
Is it just me, or do these things look like they're ready to explode at any moment?
You don't have to be Jay Leno to have a jet propelled motorcycle!
