I'm building a CNJ 4-8-0 and the valve gear is a real sticking point . I cant find any measured drawings of the valve gear I've tried 3 times by best guessing from photos but have had no luck. do you know if there is a formula to figure out the sizes by wheel diameter or piston stroke or something like that. I hope you could help.[/attachment]
