Danuzzo, congratulation on your hobby, that was my first engine also, your new hobby that take more of your time the more you get hooked, a money and tools, will be the money pit, but you can find a way to pay for them with small machine jobs that people need and looks like for some things they need getting a little harder and longer to get that is where the Home Shop will win, when I started years ago it was because I wanted something for a use I needed so hacked and sawed until it come to the part where I needed something machined, no home shop where I lived, went to professional, they would not even make the piece I needed, so I started looking for a lathe and found one, then I had something that I could not believed with out now, then started looking at what others were building that was simple and found the wobble engine, will attach pic of it, I did not even have a piece big enough to make the flywheel so I used an old cast handle off of a steam valve, my intentions were to make this one out of 1/2" stock then make another on larger by 1/2" increments until I got to 4" square and mount them all on a board with an air manifold, then I found the little steam engine Rudy Kouhoupt has an excellent book and simple projects, (by the way the one lathe I found has now turned into 12 lathes) never enough lathes ?, will attach pic of the first two that I made, have fun, there is a well spring of wisdom at this site.
