Hi John, I contacted Chester Tools some time ago about the missing forum and was told that they no longer support it. I did contribute some mods regarding the Chester 16v mill to the forum so if I can be of any help then feel free to use the private message facility. My mods concerned moving the up & down handle from the vertical to horizontal and making a fine quill adjuster and fitting a motor to the longitude axis, I also fitted a cooling fan to the motor. Hope that this helps, regards Pat
