Sure can Fionn,
Yes you are just turning the pvc pipe by hand. It will make you sleep very well at night from exhaustion. No swivel at the top.
Think of it more as a hammer. The bit you have on the bottom should have some type of small "probes" that will drive an inch or so into the ground each time you pick up the pipe and slam it back into the hole. Then simply twist the entire pipe while still maintaining downward force and twist the soil loose that your probes just drove into. Don't think of it as a drill or you will just wear yourself out due to the fact that it takes a great deal more force to "cut" into the very compacted earth than you might think. Leaning on the pipe with all your weight into it and twisting wears you out and doesn't get very far.
So to simplify all that info. The best way I have found to bore is.
Pick up the entire pipe about a foot or two.
Slam it with a lot of force into the borehole.
Twist the entire pipe to loosen the dirt.
Repeat.
