What rig are you using to balance your prop? I couldn't give you a torque value for out of balance but I can tell you what I did when I balanced the prop I carved. I had to make my own static balancer because I couldn't find/borrow one that fit my hub. I threw a pipe in a lathe and turned it down to fit into the hub (.008" less diameter than inner hub diameter). I also turned down the outside edges of the pipe to accept a couple of ball bearings I had laying around, to be placed on the outer edges of the tube sandwiching but not touching the prop. I then placed the bearings on some parallels and let the prop rotate to the heavy side, and sanded the heavy side until I could orient the prop in any 5 degree orientation (give or take) without the prop having any preference to rotate, in other words it wouldn't rotate no matter the orientation. Just a standard static balance procedure. I couldn't tell a difference between that prop or my culver prop vibration-wise. I might add that my culver prop is quite smooth, and this is wood, you will have a different procedure for adding or removing material for balancing a composite or metal prop.
