Nobody “needs” one at home. But I figure if Ryan had a CMM he’d also have a lot of other really cool stuff to play with 😎
We have a CMM with a 6’x10’ granite bed thats suspended on air at work. It’s in its own clean room. I actually considered hauling my workbench top in there before I mounted it permanently yo see just how flat I actually got it using winding sticks and handplanes. I never did but I’d have probably found out that I wasn’t nearly as precise as I imagined I was😉
