I got a Huffy off the curb(trash). It was pretty easy to convert. The extra chain rings came off by drilling the rivits that held them on this left me with just the middle chain ring. When reassembling the crank I removed the extra spacers, moving the chain line in. The rear wheel is the original cheap steel. I did not redish it because I am just using as a beater bike/loaner. I used a bottom bracket lock ring as a spacer to move the BMX freewheel out to meet the cranks chain line. It barely lined up, but it works.
