Not sure what your mobile base looks like, but if you can rig up some
threaded rod on two adjacent corners, such that the rods come nearly up
to the height of the saw, threaded thru a t-nut near the wheels on the
base, it is much easier to adjust from a standing position. I notice
the older I get, the more tolerant of wobble I become if I have to get
down on the floor to fix it!
