![]() 231 forum posts 53 photos | Quick question: I have an early 80s Super 7 with gearbox and power cross-feed. I am looking to replace my worn bed and wondered what differentiates the various beds. Specifically, what makes a bed a power cross-feed bed? |

If nothing else locate a shop with a surface grinde that will accomodate the bed. I believe that there is a difference in the bed castings, certainly between the pre and post power crossfeed Super 7's. don't know if the ML7R bed is the same as the Power Crossfeed Super 7. |
