For anyone that doesn't want to drop $$ on the snap-on pliers, just do it by hand. I do this everyday on different things, and a roll of .032" wire and wire cutters, duck bill pliers and some time is all you really need.
If you want to get tight looking wraps it isn't about how hard you pull, it is just the angle you do it at. hands wider apart = tighter looking wraps, hands closer together = looser looking wraps.
I'd rather do it by hand usually anyway.
