Hells yeah you could roll skiptooth. Its the only way to roll. Not sure if you can find a big ol' stock skiptooth ccm chainring like you want for this one (which i highly recommend.... It's great having a high geared street bike) but you were talking about having one made anyway. If you do this you don't want to take every other tooth off a modern rear cog but instead replace the rear cog with one from ichibike which pops right on most modern rear coaster brake wheels. Make sure that you file down the edges of the ichibike cod and file the every tooth on all 4 edges a bit to a point to avoid wear on the skiptooth chain. Someone else can likely provide more insight on how to do this. Loving what you got going so far. If were u i would wait or look for a legit set of antique bars and new leather wrapped grips which show up from time to time in the parts for sale section. Have fun with it and most importantly get out and ride this one when finished!
