Peanut,
You hold the tail up as straight as you can get it without bending it backwards onto the spine. It works immediately as long as there is stiff tension. No tension and it's immediately useless. The cow should be prevented from moving side to side.
I had to do my yearling steers myself. I would get them in the crappy non-hydrolic chute with the butt bar behind them. I rigged a pulley system to raise and hold the tail while I got the calcrate band (for older bulls) on them. They stayed completely still although I always worried that the tail would slip loose and I would have my head rearranged violently.
