Here is my solution. Not a good one if you need to move the lathe frequently but very good if you have to move it over an uneven surface. I rolled it across a gravel area when I had to move to a new shop. I use a cheap hydraulic lift to lift them. then the rollers are place in place. The hole in the middle is for the jack. I have half inch diameter lag bolts through the metal. I wondered if that would be strong enough but I've moved this lathe in a moving van 4 times now and even loaned them out to friends so apparently they do hold up. It does take a few minutes to install them but not very long. The biggest issue is storing them when not in use. Right now they sit in corner of my Dust collector room so they are out of the way. In my last shop I was constantly having to move them because no matter where I put them sooner or later they would be in the way.
