Would you necessarily feel vibration with an out of balance prop?

I ask this as I shortened my prop and have not sensed any vibration at any speed. Is this OK/lucky or could there be something sinister happening undetected?

either luck or you took your time and lined it up right, nice one

put your hand on the base of the gearstick to feel if there's any vibration

The best way to tell is to run a "clock" on the tube and see how much out of round it is. It is is more than 0.2mm I would recommend getting it balanced. You can do this in a lathe or on the car.

You may be lucky (very lucky)..... when I was building propshafts about 1 in 30 would not need any weight...........

PS. If you answer you havent got a "clock" to check then how did you get it straight before welding?
