No lockring? Why aren't you fellows using a english bottom bracket lockring for road freewheel to fixed hub conversions? The freewheel hubs that I have converted had enough threading to accept a fixed cog and a BB lockring.
Granted it isn't reverse threaded but it does act to lock the cog threads to the hub via compression much like double nutting. I think in most cases (not including frequent skidding), a BB lockring can be used without the additional provision of blue locktite.
