This is my take on the compressed air engine design by Philip Duclos, published in the book ‘Steam & Stirling Engines You Can Build Vol2 (1994).
The original plans are in Imperial – to me that’s OK for woodwork, but for precision my mind works in metric 🙂
First, I built the model in Inventor, tweaking the measurements to give ‘nice’ decimal numbers, and replacing screws and bolts with the nearest metric equivalent.
Did a simulated run to see if it looked like it would actually work and not bottom out somewhere.
Then make drawings for each part.
Everything was made from scrap bar or square stock.
And, of course, a nice render.
