Can a cookie cutter pegasus that was not orignally set up for neon be fitted for neon w/o extensive modification to the sign? Thanks CRAIG Z

To keep from breaking up the glass (porcelain) you would have to have a cutter that would grind through the glass and then the steel back. A diamond cutter comes to mind. Have absolutely no experience with this but try a glass and mirror shop. They cut holes in glass all the time. Steve
