Re: Extending a Hex Shaft?

So as a follow up to my original suggestion, first buy a Banebots P60 and then DIY the output shaft.
You should reconsider. In industry, planetary gearboxes are the go to gear boxes for high torque applications. The versaplanetary's load carrying capability is only limited by the aluminum hex shafts ultimate strength. It is stronger than its spur gear counterparts.

It has larger output bearings and a 28 tooth 0.5 module spline that has incredible load carrying capability.
