Hi Peter B.
I really like your design for the steady rest. It will go nicely with my Monster Hollowing rig. I saved a couple of pictures and hope to remake the smaller one I now have.
Your wheels look like the Lee Valley ones? I looked at them when they first came out but decided they were too large in diameter, so I am sticking with the set of old roller blade wheels that I bought from a good will store for $5.00.
I have the wheels on a smaller round 10" Steady that I made years ago for my first lathe.
