i don't think you really need tugs to get good tension As long as your chainline is good, just pull the wheel as far back as you can with your hands (centering it in the stays), and tighten the wheel evenly with a spanner.
if your chainline isn't that good or you just more tension, get the wheel as far back in the stays as it will go, then bend the wheel to the right whilst simultaneously tightening up the right nut. Then, after the right side of the axle is tight, re-centre the wheel in the stays whilst tightening up the left side. Chain tension should be fine now.
