It was time for another model engine. This time I picked a Lehmann Hot air engine because it has such an interesting linkage motion.
Except for the bolts and screws, it was built entirely from scraps, even melted down some old motorcycle parts for the castings. It turned out great and is one of my best running hot air engines. From what I've read about them, the original engines were some of the best. It has been a most satisfying project. Construction time approximately 5 weeks.
