      Get it big and get it deep- the top of the footing needs to be below the frost line. Concrete is cheap, but if it heaves you will wish it had been better.   18" diameter and deep, 8" minimum footing thickness. Tamp the bottom and add an inch of gravel, then the rebar in 4 # (like that) criss cross 16" pieces wired together. Then drive the verticals ||| and wire them to the footing # rebar. Pour the footing and strike it level. After the footing cures a day, add the sonotube over the vertical and figure out the mount details (the threaded rods). Suspend them from a disk of ply, pour to full, then push the threaded rods into the wet mix. Align and have a drink, cure 3-4 days.

      Thanks!  I can't reach under my slab to pour that size.  I will be digging in an 18" circle hole in the slab.    I could dig a cone perhaps, with a flat top, then pour the pier.

      Put in a footing below the local frost line. 16x16x8 would not be too much. Form it and place gravel at the bottom. Strike off the top around the rebar of the column. Pour tge column as a second pour.
