A friend wants to get into hobby cnc and wants a small machine. Sherline is too small. Really looking for either an off-the-shelf mill already converted or a complete kit where you just buy the HF or Grizzly or whatever plus the complete conversion kit and bolt them together. He does not have a machine shop to make stuff, so it has to be just bolt-together or come ready to go. Who makes kits to do this? Thanks. cnc1000
