I most recently made standoffs for a friend from a round wood broomstick. Very hard wood, maybe ash, it was a 50cc gasser and the sticks were 7/8 inch diameter. I cut them with the cross slide on my bandsaw and then set them up in the "V" grip of my drill press vice to drill through the center. We really tightened them up and there was NO compression of the wood! Cheap and very effective, plus we made them the length we needed. I rounded the cut off end of the broom handle and the shorter length was not even noticed.
