Why go for idler gears, surely it would be simpler to just have 1 large gear turning 3 large gears attached to the wheels and do the 2:1 reduction else where, such as with the belts/ chain driving the modules or in the gearbox ( custom 3rd stage to get adequate reduction etc)

Also were the plates made by hand?, looks like some pretty precise metal work

What you ended up with looks very nice, what made you change your plan about making custom gears rather than purchasing COTs ones, you seemed set on making them earlier in the season.
