Am sure it will Tim, you'll be designing your own engines next! I quite enjoy doing these simple little engines, it's satisfying to see them go from concept to a set of drawings and a working engine that actually resembles the drawing!
However, another part of me just thinks, don't re-invent the wheel and just use somebody elses design because time spent on the computer could be time in the workshop!
Bit of a trade off I suppose!
