We had a guy scrape a hardened bed on an old Mori SL65, he did a fantastic job actually, but took him a week to do 25 inches, and he was a master fitter. That machine still runs today, 15 years later. Either way, this is not a job for a beginner, and the V ways make it even tougher to do. Even if you did find someone to grind in your area, you still have to deal with gibs and saddle fitting.
