hi! i have been planning to build miniature engines ever since i saw some clips on youtube... because i build and restore old bikes and cars, i recently bought a small laith and a drill/mill and i have had some training when i was in highschool. so i'm confident i have enough basic skills to venture on this path! however, i don't want to bite of more than i can chew so i'm wondering if anyone has any suggestions on a good first build? i believe a one-cylinder steam or compressed air-type engine would be a good place to start before i take on V8's and whatnot any good plans out there? being from Europe, preferably in mm's rather than inches...
