And you ride this brakeless? You have more balls than I. I've build a SS in this fashion but not a fixie. Doesn't the freewheel just screw on? I would worry about either the weld breaking or the freewheel spinning off. You should look at the surly product that replaces the freewheel and offers a lockring. Put a brake on that thing so you will be also onelessScar as well.
