The Mesh is extremely important on casted gears; There is no shortcut at that.
However, Tamiya does not make metal parts in the house. Therefore the gearbox has two different pressure angles on the gears, Old standard and new. Witch makes the gear to go down faster than it would with the same pressure angles. Now Japan is a monoculture, so the boss does not know that, and a new gearbox or axles will not be on the horizon for some time. But the work so I stick with them.

Yea its very odd all the axles ive built so far have been spot on besides that one pinion that has free play but ill get it sorted!

Today I started designing the solution for the weakest part in the gearbox, Hope it will work as good as I hope.
