Shaun, exactly what i was going to say. As leverage goes, there is no point in going longer than the rim diameter. I preferred to use 2 hands on the rim.
If your freewheel has a remover that bolts on rather than a loose spline, then the firm pressure will help release it.
For the clamp bolt it could be possible to tap it out a little larger.
