I haven't used or bought a .750 diameter roller wheel lifter solid roller lifter in a lot of years; most are .820"+ now
I have several older Starrett dial indicators and some cheaper imports, the imports don't read or follow the lifters as well as the Starrett's due
When you think of the contact patch on a .750 wheel versus a .820 wheel on the lobes the difference can't be very much
My point is the hang time going over the nose at max lift and then descending on the downhill side can't be very bunch
