This gearbox's tight spread would either have a limited top speed or a low gear too fast to accomplish indefinite pushing. If your design objectives are different, that's fine; I was just curious what your intent here was.
Well to be honest this gearbox was simply a design exercise. I have heard the rule of thumb about gearing low enough to push for 2 minutes without tripping a breaker. But isn't that usually against the rules? I'm not sure why you would want to gear that low.
