I was looking through a Sportsman's guide catalog the other day, and they were selling motorcycle helmets, full face versions with visors for $60. Now, I know almost nothing about it, but I got to thinking, has anyone tried to convert a motorcycle helmet to a Halo MC helmet? I've seen the Boba Fett batting helmet conversions, and I've seen one that GoldCylon is making [a halo helmet from a batting helmet] but what about building up a cycle helemt instead? Cheap helmets can be found at flea markets, trade day weekends, and pawn shops. Thoughts? Obstacles? Issues?
