Do you know how hard is it to drill and tap a shaft of that servo
motor, coaxially, to install a stem to mount the encoder disk?

Is the shaft hardened?


Motor shafts are generally fairly soft in my experience though I suggest
check and see if it can be easily molested with a file.

I would probably spin in a lathe using a roller support opposite the chucked
end and spot, drill then ream.
