Extending a Hex Shaft?

What diameter clearance do you have? you could get quite creative with bolting some hex hubs together with standoffs.

possibly take a tube with a close enough inner diameter and shoot two pins through it to retain the shafts?

The VersaPlanetary 1/2" hex output also has a 1/4-20 hole in the end, you could possibly tap the end of the other piece of hex shaft, take a short piece of threaded rod, twist the two together then take a 1/2" Hex shaft collar on the outside to overlap the two which would transfer the torque.

Just spitballin here

I did not realize that versa planetary gearboxes came with a hole on the end.
Just use the male end half inch hex standoffs from mcmaster I posted the link earlier.
