after stripping two hubs, i decided to lace up a front disc hub and bolt a cog on. drilled out a ss cog myself and the chainline worked fine. havent had a single problem with the hub in 4 years. originally the holes werent perfectly drilled, but because the splines on the cog were slightly smaller in diameter than the hub flange, it was easy to sand around with a dremel quite evenly to avoid eccentricity
