Hi I have had my Build of Tops Heavy CNC up and running now for about 2 years. It is a dream to use and I have done some super work with it. I was very tempted to upgrade the machine to the Heavy Metal version, however I have a need to incorparate a 4th / rotary axis. I have searched the forum topics but can not find any information as to this addition. is there any one that has made this modification or is concidering the joint design of sutch a modification?

I look foward to hpofully a lively discussion on how this should be done, or maybe the design of a stand alone rotary cnc router.

thanks in advance

Kelvin
